In this blog, we will explore what network topology is, its significance in understanding an organizational network and how you can use network topology maps to visualize the complete network of an organization. We’ll also discuss how Network Glue can help you easily visualize your or your client’s entire network and automate documentation in the network devices

What is network topology?

Network topology focuses on the arrangement of various components in a network, including the physical and logical description of how nodes and connections are made in a network. At its core, network topology aims to define the paths that data packets travel within a network. Understanding this layout is crucial as it helps network administrators optimize data flows and ensure efficient traffic management, leading to enhanced overall network performance.

Knowing the topology also helps identify potential bottlenecks and points of failure, thereby facilitating better planning for network expansion and troubleshooting. This understanding is fundamental for maintaining robust and responsive network infrastructure in any business or organizational environment.

Why is network topology important?

Network topology helps you understand the different components in your network and how they are connected. Moreover, it plays a critical role in the function and performance of a network.

In organizations with large networks, network topology is crucial because it:

• Enables a better understanding of networks: Knowing the network’s topology helps IT pros visualize and comprehend how different nodes (like switches, routers and servers) interact. This understanding is key to optimizing data paths and managing resources more effectively.
• Reduces maintenance and operational costs for networks: Effective topology management can streamline network maintenance and reduce costs. For instance, in a well-organized network, identifying redundancy and optimizing pathways can minimize downtime and the need for frequent, costly repairs or upgrades.
• Helps determine the media to be used to cable a network: The choice of cabling — coaxial, fiber-optic or twisted-pair — can depend on the network’s topology.
• Ensures smooth communication between various components: A well-planned topology facilitates smoother and more reliable communication between devices. It helps design pathways that reduce latency, manage bandwidth more efficiently and improve overall data transfer speeds across the network.
• Helps identify the problem areas in a network: With a clear layout of the network topology, IT teams can more quickly pinpoint issues such as bottlenecks, failed nodes or inefficient routing. This speeds up troubleshooting and restoration, enhancing network reliability and performance.

What does network topology include?

When you have a well-defined network topology, it makes it easier for network admins to identify issues, allocate resources, troubleshoot problems and more. We can broadly categorize network topology into two types — physical and logical.

Physical topology

The physical topology of a network concerns the physical connections between various nodes in a network. These are actual connections made with the help of wires and cables. This gives you a complete overview of how all the network components come together.

Logical topology

The logical topology of a network concerns things beyond the physical connections of a network. It gives you an overview of data transfers that happen within a network. It also includes how a network is set up, how the nodes connect with each other and how data travels between different points.

Types of network topology

Beyond physical and logical topologies, network topologies can be categorized into several different types. Choosing the right topology is critical since it can make or break your network. Different types of network topologies serve different purposes so that you can choose the right one based on your network size and objectives.

Point-to-point topology

This is the simplest type of network topology. Here, two nodes are connected directly to each other with the help of a common medium. Since there are only two nodes in this network, the entire bandwidth is reserved between the two nodes.

Advantages:

• This is the simplest and most low-cost option for creating a computer network.
• Since there are only two nodes, it is easy to maintain.
• This has the least delay in communication compared to other network types.
• The direct connection reduces the potential for unauthorized access compared to networks with multiple nodes.

Disadvantages:

• Since there is only one common link, the network stops working if the link is down.
• This can have a maximum of only two nodes in the network.
• Can be used only when the two devices are in close proximity.

Usage:

• Point-to-point topology, due to its straightforward and direct connection between two nodes, is particularly useful in specific settings where simplicity and direct communication are essential. Many home internet setups utilize point-to-point topology, where the home router is directly connected to the internet service provider’s modem.

Bus topology

In this type of topology, network devices are interconnected with the help of a single cable running from one end to the other. Due to this, it is also referred to as backbone topology or line topology. In bus topology, data travels along the route of the network cable and moves in one direction.

Advantages:

• This is ideal for small networks since it is cost-effective.
• It is easy to add more devices here simply by adding more cable.
• The network structure here is easy to understand.
• Works well within a small area where all devices are located close to one another.

Disadvantages:

• If the main cable goes down, the entire network goes down.
• This is ideal only for small networks since data transmission gets slower with the addition of every extra node.
• The data transmission is unidirectional and cannot be sent back in the opposite direction.
• Pinpointing problems can be challenging because the entire network may be affected by a fault in just one part of the cable.

Usage:

• Bus topology is ideal for setting up temporary or ad-hoc networks, such as those needed in conference settings or workshops. These networks typically require quick, temporary setups with minimal infrastructure, making the simplicity of bus topology a perfect fit.

Ring topology

In ring topology, the nodes are arranged in the shape of a ring. Each node has exactly two neighbors, and the devices are connected to form a circular loop. Here, the data travels in a circular direction and passes through all intermediate nodes. The data transmission is mostly unidirectional; however, it can travel in both directions by establishing two connections between the nodes.

Advantages:

• This topology can manage heavier loads than bus topology.
• Since data travel happens at only one station at a time, it eliminates the chances of packet collision.
• It is easy to identify misconfigurations or issues in this network.
• Its organized structure facilitates consistent data speeds around the ring, enhancing overall network performance.
• It is cost-effective for certain layouts, like when nodes are geographically positioned in a loop.

Disadvantages:

• The entire network will go offline if one node malfunctions.
• If there are multiple nodes in the network, a proportional transmission delay might take place.
• Reconfiguring, adding or removing nodes requires shutting down the entire network.
• Establishing it can be complex and requires careful planning.

Usage:

• Ring topology is valued for its orderly network flow and enhanced fault isolation, making it suitable for specific network configurations where data loop integrity and predictable topology are priorities. For example, they are often employed in high-speed network backbones, such as those used by internet service providers (ISPs) or large-scale enterprises, to facilitate data transmission across a resilient, closed loop.

Star topology

Star topology has a central node or hub that connects to all other nodes in the network. Each node in the network is indirectly connected to other nodes using the central hub. Besides connecting all nodes, the central hub also acts as a repeater to ensure there is no loss in data transmission.

Advantages:

• Failure of a single node will not impact other areas of the network.
• Nodes can be reconfigured, added or removed without shutting down the network.
• Since it is easy to troubleshoot, it makes life easy for network admins.
• Since each node connects individually to the hub, security measures can be applied centrally at the hub, enhancing the overall security posture of the network.

Disadvantages:

• This network is vulnerable to the failure of the central hub.
• It is expensive to set up and operate.
• Performance and transmission speed are highly dependent on the central hub’s configurations.
• The requirement for each node to have its own cable to the hub can lead to extensive cable use, which can be costly and difficult to manage, especially in larger networks.

Usage:

Star topology is widely used in various networking environments where centralized management and scalability are key. For instance, in corporate office networks, devices like computers and printers connect to a central router or switch. This setup simplifies network management and enhances security, making it ideal for maintaining large-scale business operations.

Tree topology

Tree topology resembles a tree-like structure with one root node and other secondary nodes connected like branches. This is made by connecting star networks with bus networks. Hence, it is also called star-bus network topology. Here, all the nodes are connected to each other hierarchically.

Advantages:

• It is easy to manage and is ideal for large networks.
• It enables scalability since it supports easy addition and removal of nodes.
• Troubleshooting is easy since you can analyze different branches for issues.
• Resources and data can be efficiently managed and routed from the root to various branches, optimizing network performance.

Disadvantages:

• The hierarchical layout requires careful planning and management, which can complicate installations and upgrades.
• While it isolates issues to branches, failures at higher hierarchy levels (like the root) can impact large segments of the network.
• It is expensive due to the sheer number of nodes and the amount of cabling involved.

Usage:

• Tree topology is ideal for large organizations with multiple operational branches. For example, it is often used on educational campuses where different buildings or departments (branches) connect back to a central data center (root). This setup allows the university’s IT department to manage network access and security centrally while providing reliable connectivity across various facilities.

Mesh topology

In mesh topology, every node directly connects to other nodes in a point-to-point connection and in a non-hierarchical manner. Since it has a web-like structure, the network is not dependent on a single node. Data transmission occurs through two different methods – routing and flooding. In the routing method, data travels through the shortest distance between two points. In the flooding method, data packets are sent to all nodes in the network without using any routing logic.

Advantages:

• Since it is fully connected, it is more reliable and stable than other networks.
• Faults can be pinpointed and addressed without impacting the broader network, thanks to the individual connections between nodes.
• Direct connections can be more securely managed, reducing the risk of interception and data leakage.

Disadvantages:

• The high number of connections increases the cost of cables and network interfaces, along with the complexity of setup.
• Due to the complexity of design, it requires considerable time and technical expertise.
• While it’s technically possible to add more nodes, each addition requires significant reconfiguration to maintain full mesh connectivity.

Usage:

The resilience of mesh networks ensures uninterrupted communication even in challenging environments. It is thus ideal for military bases or field operations where communication must remain intact despite potential node damages or failures.

Hybrid topology

When you create a network topology by integrating two or more topologies, you get a hybrid topology. These are commonly found in large organizations where departments with different network topologies are integrated under one hybrid structure.

Advantages:

• Hybrid topology allows for the customization of the network to meet specific departmental needs while still integrating into the overall organizational structure.
• As organizational needs grow and change, it is easier to scale and expand.
• By combining multiple topologies, hybrid networks isolate failures within one segment without impacting the entire network.

Disadvantages:

• Network administrators must understand multiple topologies and their interactions, which demands high skill levels and extensive training.
• It can be quite expensive to integrate different network types into a single network.
• The complexity of hybrid networks can make management and troubleshooting more challenging and time-consuming.

Usage:

• Hybrid networks, with their adaptable and resilient nature, are particularly suited to environments where different areas of operation have distinct networking requirements but must still be integrated into a coherent system. For instance, in healthcare facilities, patient management systems require high security (ring or mesh), whereas administrative functions need only a simpler one (bus or star).

Frequently asked questions about network topologies

Here, we answer some of the most asked questions about the nature of network topologies to help clarify their applications and benefits.

What is the simplest network topology?

Answer: Point-to-Point

The simplest form of network topology is the point-to-point topology. It involves a direct connection between two nodes, making it extremely straightforward to set up and manage. This simplicity comes from the fact that there are no intermediate devices or network segments; data flows directly from one point to another. The point-to-point topology is ideal for small-scale operations where only two devices need to communicate, such as a single PC connected to a printer.

What is the most common network topology?

Answer: Star

The star topology is the most prevalent network topology used today, particularly in business networks. This popularity is due to its robustness and the ease with which it can be managed and troubleshot. In a star topology, all peripheral nodes (computers, printers, etc.) are connected to a central node, typically a network switch or hub. This setup simplifies network management because each device only needs to communicate with the central hub, which then manages network traffic to other devices. Additionally, the failure of one peripheral node doesn’t affect the rest of the network, making it highly reliable for environments where network uptime is critical.

What is the most reliable network topology?

Answer: Mesh

For reliability, the mesh topology stands out as the most robust. In a mesh network, every node is connected to every other node, which provides multiple pathways for data to travel between any two points. This redundancy is crucial in scenarios where network reliability is paramount because the failure of any single connection typically doesn’t bring down the network; data packets can simply be rerouted through alternative paths. Mesh topologies are particularly useful in applications requiring high levels of data integrity and uptime, such as in financial institutions or military operations, where every second of downtime can have significant consequences.

How to make a network topology map

Creating a network topology map begins with developing a general layout of your network and listing all the key components, including computers, servers, connections, ports, hubs, routers, etc. Once you have created the layout, you can go ahead and draw the network. While this may work for a small network with a few devices, it is not applicable for large networks with a complex design.

What is SNMPv3?

Simple Network Management Protocol Version 3 (SNMPv3) is an advanced version of SNMP. Primarily used for network management, SNMPv3 ensures secure access to devices by providing enhanced security features. Unlike its predecessors, SNMPv3 supports strong authentication and encryption, making it a go-to choice for managing complex network environments securely.

SNMPv3 is crucial in contemporary network management for its ability to provide secure and reliable data about network devices. Its enhanced security features make it well-suited for modern, sensitive environments where data integrity and privacy are paramount.

Why is SNMPv3 important?

In an era where cyberthreats are becoming increasingly sophisticated, the security of network management protocols is non-negotiable. SNMPv3 addresses this concern by offering robust security measures, ensuring that the management of network devices and the transfer of critical information happen in a secure, encrypted manner. For IT professionals, this translates to peace of mind, knowing that their network’s integrity and performance are not compromised.

How does SNMPv3 work?

SNMPv3 operates on an advanced framework that significantly enhances the security and efficiency of network management. Here’s a technical breakdown of how SNMPv3 functions:

1. Architecture: SNMPv3 retains the basic structure of SNMP, which includes an SNMP manager and SNMP agents. The manager sends requests to agents residing on network devices, and these agents send back responses. However, SNMPv3 introduces a modular architecture comprising three primary components:

• Security subsystem: Responsible for authenticating and encrypting data packets.
• Access control subsystem: Determines whether an SNMP request from a user should be processed or denied.
• Message processing subsystem: Encodes and decodes packets and maps security models to SNMP versions.

2. User-based security model (USM): At the core of SNMPv3’s security enhancements is the USM. USM provides:

• Authentication: It ensures that a message is from a legitimate source. SNMPv3 supports stronger authentication protocols like HMAC-MD5-96 and HMAC-SHA-96. These protocols use a secret key and a hashing algorithm to generate a message digest, which is sent along with the message.
• Encryption: To maintain confidentiality, SNMPv3 uses encryption algorithms, such as DES, 3DES or AES, to encrypt the payload of the SNMP message. This prevents unauthorized entities from reading the content of the messages.

3. View-based access control model (VACM): VACM in SNMPv3 allows for finer control over access to managed objects. It defines who (the user) has access to what (the object) and how (the level of access like read-only or read-write).
4. SNMP messages: SNMPv3 operates using different types of messages (or protocol data units (PDUs)) for various operations:

• Get: Request to retrieve a value from an SNMP agent.
• Set: Request to change a value on an SNMP agent.
• GetNext: Request to retrieve the next value in a table or list.
• GetBulk: Request multiple values in a single request (useful for large amounts of data).
• Inform: Used between managers to communicate information.
• Response: Reply from an agent to a manager’s request.
• Trap: Asynchronous notification from an agent to the manager.

5. Communication flow: The SNMP manager initiates the communication by sending a request to an agent. The USM module in the agent authenticates and decrypts the message. Then, VACM checks if the requester has the necessary access rights. If all checks are passed, the agent processes the request and sends back a response, which is encrypted and authenticated for security.
6. Secure data handling: Throughout this process, SNMPv3 ensures that data is handled securely. Authentication prevents tampering and spoofing, and encryption safeguards data privacy during transmission.

In summary, SNMPv3 works by employing advanced security mechanisms for authentication, encryption and access control. These features make it an ideal protocol for securely managing and monitoring network devices in a wide range of environments.

How does SNMP improve security?

Simple Network Management Protocol (SNMP) plays a crucial role in enhancing network security, particularly in its third iteration, SNMPv3. Unlike its predecessors, SNMPv3 introduces robust security mechanisms addressing authentication, privacy and access control. At the heart of its security improvements is the user-based security model (USM), which allows for strong authentication protocols, such as HMAC-MD5-96 or HMAC-SHA-96.

These protocols verify the identity of users sending requests, ensuring that only authorized personnel can access network data. Additionally, SNMPv3 supports encryption algorithms like DES, 3DES or AES, which encrypt the data payload, thereby protecting sensitive information from interception and unauthorized viewing during transit. This is especially vital when managing devices over unsecured or public networks.

Furthermore, SNMPv3’s view-based access control model (VACM) allows for granular control over who can view or manipulate specific network information, further tightening network security by restricting access based on defined roles and responsibilities. These technical advancements make SNMPv3 a more secure and reliable choice for network management, ensuring the integrity and confidentiality of critical network operations.

Common challenges of SNMPv3 and how to overcome them

While SNMPv3 enhances security, its implementation can be complex. Setting up SNMPv3 involves configuring users, authentication methods and encryption settings. This complexity can lead to misconfigurations, posing potential security risks. Overcoming these challenges involves thorough planning, proper training of IT staff and leveraging tools like IT Glue’s Network Glue add-on, which simplifies the process of automatically discovering and documenting devices that have enabled SNMPv3.

How can SNMPv3 help your business?

SNMPv3 can significantly benefit businesses by providing a secure and efficient way to manage network devices. Its robust security features protect against unauthorized access and data tampering, ensuring the confidentiality and integrity of network data. This is especially crucial for businesses handling sensitive information. Additionally, SNMPv3’s ability to provide detailed and accurate network information aids in troubleshooting, optimizing network performance and making informed decisions about network management.

In this blog, we shall explore network mapping, its different aspects and how you can leverage it for the smooth functioning of your network.

What is network mapping?

Network mapping refers to the process of representing an entire network, along with its devices and interconnections, in a visual format. By discovering and visualizing all the assets in a network, you can create a network map or diagram that includes all vital components of a network.

This visualization will be useful during network maintenance when administrators must understand the entire network infrastructure to develop effective solutions.

What is the purpose of network mapping?

The primary purpose of network mapping is to gain visibility into a network. To have a network that functions seamlessly, you need to understand all its components fully. With network mapping, you can quickly identify all the bottlenecks in your network so that you can address them and keep your network up and running without any issues.

Why is network mapping important?

When you have network mapping in your IT infrastructure, your technicians don’t have to guess where an issue is happening. By allowing technicians to observe the problems occurring in real-time, network mapping helps them identify and fix the problems before they escalate.

For instance, a server malfunction can cause an unexpected downtime in your network. Without proper network mapping, your technicians would have to review various network components or the entire application stack to identify the issue. However, with automated network mapping, you can quickly check how your servers, endpoints and other networking components work. This makes network maps a critical part of your IT infrastructure.

What is a network map?

A network map refers to a document that visually represents a network. A typical network map consists of all the devices in a network, along with their interconnections and information flow. The information you find on a network map, including the network’s physical architecture and other related data, cannot be accessed through any other means.

Modern networks are complex and dynamic. To keep your network maps up to date, you need to use robust solutions that can automatically create network maps and provide the latest information on a network.

What are the different types of network maps?

Network maps can be broadly classified into two types: physical and logical. Both have their purposes when it comes to network architecture. When constructing a network for your organization, you need to weigh the features and benefits of both these network topologies and choose the ideal one that best suits your purpose.

• Physical network map: In a physical network map, the visual image is constructed based on the arrangement of various network components. If your network has components like endpoints, servers, printers and routers, a physical map will help you visualize how you can connect these devices with the help of wires, cables or wireless networks. A physical map is very helpful in identifying network issues caused by the malfunctioning of these devices or their connections.
• Logical network map: A logical network map illustrates how information flows through a network. Rather than showing how you can connect various devices, this map shows how various devices in a network communicate with each other. By analyzing the information flow in a network, you can identify potential issues that may arise with data transmission in a network.

What should a network map include?

To build a robust network map, you need to focus on various components and understand their role in your network infrastructure. A network consists of multiple components, such as hardware devices, software programs, connectors and controllers. All these components have specific purposes and are integral to keeping a network active.

Here’s a list of items you should include in your network map to gain the most value:

• Network devices: A network comprises various devices, and these devices have specific roles to play. For instance, an endpoint provides users access to the network and allows them to connect and exchange information. Similarly, we have other devices for managing resources, transmitting data, connecting data points, storing data, etc. A proper understanding of these devices will help you build efficient networks that ensure seamless communication and security.
• Network connections: Network connections bring together various devices in a network and allow them to exchange resources. These connections can be wireless or connected with the help of cables. Either way, a network map should provide clear information on how various devices are connected and exchange information.
• Network topology: Network topology focuses on the logical arrangement of multiple components in a network. Different network topologies can be used for different purposes based on the type of communication you require between nodes.
• Routing protocols: Network routing protocols provide information on how routers communicate with each other. It specifies a router’s best path to carry the data packets efficiently. A network map will help you identify the best routes for your data and the optimal way for information to reach the destination.
• Domain controllers: You can use domain controllers to authenticate users trying to access your network. These are servers that centrally manage all your user accounts and provide verification for network access.
• Traffic flow: Traffic flow influences the quality of your network. If the traffic is too high, data packets often get stuck at various nodes, affecting seamless transmission. Your network map should help you manage network traffic effectively by spreading out the traffic evenly.

How does network mapping work?

A network mapping solution uses active probing technology to update the network mapping information. In this process, probe packets will be sent to different nodes in the network to collect information like IP addresses, device configurations and other technical data. The data collected from these probes can be used to draw an object on the network map. A robust mapping tool will help you do this automatically and provide updated information about your network.

Most network mapping solutions use a mapping protocol to discover devices and automate the mapping process. Simple Network Management Protocol (SNMP) is one of the most widely used protocols to map a network. Here, the network components are treated as variables, and the probes will constantly send information on their setup and status.

Complex networks deal with vast amounts of data that can be accessed simply by leveraging the probing mechanism in the mapping solution. Modern mapping solutions collect advanced information from the networks to provide details like CPU temperature, power status, memory level and active ports. These details often come in handy when technicians must work on specific devices to fix complex issues.

What are the uses of network mapping?

Considering the complexity of today’s IT environments, network mapping plays a huge role in the seamless performance of a network. Here’s a list of reasons why network mapping is widespread in modern IT networks.

• Complete network visibility: Network mapping helps you visualize the entire network easily. As a result, you can easily spot minor defects in your network before they become full-blown issues. Also, automated network mapping helps you identify the changes made to the network instantly.
• Monitoring and management: Maintaining your network performance requires continuous monitoring and management. It is impossible to monitor your network performance without getting complete visibility.
• Quick diagnosis of network issues: Even if your networks run into significant problems, you can easily diagnose the issue with the help of a network mapping tool. Without a network map, it will take forever to identify a specific issue in the network and even more time to resolve it.
• Security and control: With better visibility into your network, you can easily identify who can access it and for what purpose. As a result, you can exert better control over your network security and prevent unauthorized access.
• Better planning and forecasting: In today’s world, many organizations are constantly scaling up, and networks are getting bigger as a result. If you are expanding your network, you need better visibility into its current structure. Network mapping also helps you precisely formulate the best expansion strategy.
• Compliance support: Many data privacy laws have specific provisions for implementing controls at the network level. To adhere to these regulations, you need proper network mapping performed with the help of a robust tool. This helps you proactively monitor your networks and mitigate any risks as and when they arise.

In this blog, we’ll explore the significance of relationship mapping in today’s complex IT environments and how you can use it for effective information management.

What is relationship mapping?

Relationship mapping refers to how individual components are related to each other in an IT infrastructure. Here, you need to understand the logical relationships between various assets and their documentation. For instance, when you relate components like hardware devices and their configuration documents, you can instantly access the documents while working on understanding the hardware devices. Similarly, you can have easy access to all the information you need and use them whenever you want through relationship mapping.

What is the role of relationship mapping?

To start creating relationship mapping, you need to have building blocks. This includes your company’s technology assets such as desktops, servers, other infrastructure hardware and software applications.

You also need to build relationships with the rest of your IT, including software applications installed on devices, passwords to access the devices, and knowledge and how-to guides for troubleshooting the devices. This is what relationship mapping does. By linking your assets with the rest of your IT, you can have access to critical information at your fingertips.

In large organizations with complex IT environments, information often gets buried and can be extremely difficult to locate. Even when you have sophisticated documentation with multiple layers, relationship mapping makes everything easier to understand since you aren’t bouncing between different tools to find that one piece of information you need.

Why is relationship mapping important?

The most important aspect of relationship mapping is to provide you with a full picture of your clients’ IT environments. You can enter all assets in your relationship mapping tool and create logical, two-way relationships between them. Following that, you can check the dependencies and relationships for a single IT component. With this, you can easily understand what’s at stake whenever a new problem is identified within the network.

This logical structure ensures better information management and drives performance as a result. In other words, relationship mapping provides you with actionable insights into your IT assets and helps you connect the dots in the asset management process.

What are the benefits of relationship mapping?

The biggest benefit of relationship mapping is that it provides instant access to critical information even if you have a complex IT infrastructure. This drives performance and helps you make informed decisions. You can identify issues instantly and troubleshoot them or incorporate temporary fixes until a permanent solution is found.

Here is a list of reasons why relationship mapping is extremely important in IT environments.

Reduces research time

Let’s face it. Sifting through multiple Excel sheets or Word documents to gather information about a single endpoint isn’t just tedious but practically impossible in today’s age of complex networks. When you have a map of logical relationships between various pieces of information, you won’t have to search for everything manually. From ticket resolutions to project management, technicians save a significant amount of time every day with relationship mapping.

Accelerates troubleshooting

IT professionals receive tickets every day about workstations not functioning well. Also, MSP technicians receive complaints from their clients about issues in multiple workstations. When working on these fixes, you may need access to various information, including vendor info, hardware details, passwords, SOPs, etc. Imagine trying to search for this information through huge volumes of unstructured documentation. Sounds daunting, doesn’t it?

With relationship mapping, you can instantly isolate information pertaining to a specific device and get preliminary information like connected devices, software installed, firewalls, etc. This accelerates troubleshooting and helps resolve complicated issues instantly.

Promotes self-service culture

Having a documentation tool with relationship mapping features is a great way to empower your technicians. When technicians understand the relationships between various elements in the network, they can work on their own without waiting for information from multiple sources.

This helps you avoid issues arising from simple forgetfulness or misplaced information. With all the relevant information about the IT infrastructure right at their fingertips, technicians can be more independent and proceed to resolve issues on their own more confidently.

Comprehensive understanding of your IT environment

In many complex IT infrastructures, relevant information can get buried deep inside the environment without the possibility of instant access. As a result, network administrators have to painstakingly go through various documents and Excel sheets just to get an understanding of their network.

You can overcome this with a powerful documentation tool that has relationship mapping capabilities. By getting instant access to related items in your IT environment, you can get a complete understanding of how your devices are connected and how they interact with each other.

Speeds up onboarding

When onboarding a new technician to your team, you need to provide them with a full understanding of the devices you manage. However, providing a manual overview of the entire infrastructure can be overwhelming. Relationship mapping can come in handy during the onboarding process. By providing a glimpse of all the components in the network with the help of a relationship map, you can speed up your onboarding process and get your technicians accustomed to their work in no time.

What are relationship mapping tools?

Relationship mapping tools are software solutions that help you map relationships between assets, giving you a full picture of your clients’ IT environments. In a relationship mapping tool, you can enter all your assets and create two-way relationships between them. This provides you with information on the dependencies and relationships for all IT components.

When you get the relationship information between your assets through a relationship mapping solution, you can easily understand what’s at stake if you encounter a problem within your IT infrastructure. Robust tools like IT Glue also provide you with a logical structure to manage your information better. This drives performance and helps you identify permanent solutions whenever a new issue is encountered.

What Is a Network Diagram?

A network diagram provides a visual representation of how a computer or telecommunications network works. It visually depicts the various components that make up a network, including routers, devices, hubs, and firewalls, and how they interact with each other. Considering the different interdependencies in any given network, these diagrams use graphics to visually represent these dependencies and interdependencies.

What is a network diagram used for?

A network diagram eliminates guesswork when it comes to troubleshooting network configurations. It provides a visual illustration of how different network components are related to each other. Technicians can use this information to save valuable resources, such as money and time, when working on a network. The visual display of various components working seamlessly can help identify specific areas where errors or problems occur.

What are the benefits of network diagrams?

There are several benefits to having network diagrams for your IT network.

• Organizations cannot afford lengthy downtime for maintenance in today’s competitive scenario. With a reliable network diagram, you can quickly sort out network issues and get back online.
• Network diagrams can also help increase efficiency as it eliminates the time wasted by technicians on identifying the source of an issue.
• Since all components are identified in a network, you can use this information to plan, organize and control the workflow in your network. When executing major tasks, you can use this illustration to get them done efficiently.

What Should a Network Diagram Include?

A general network diagram can provide a high-level perspective of your network as well as a more specific description. A comprehensive diagram will include more information while a general diagram will have a cleaner layout with only the most important framework.

What are the components of a network diagram?

Creating a network diagram starts with listing out the components you are likely to use. The key here is to not leave out any network components. Some of the key components include the following:

• Workstations & PCs
• Servers
• Mainframes
• Mobile devices
• Routers
• Printers
• Scanners
• Firewalls
• Switches
• Hubs
• Modems

What Are the Different Types of Network Diagrams?

From simple hand-drawn pictures to sophisticated software illustrations, network diagrams can vary a lot from one to another. A typical network diagram contains various lines and nodes that are represented by different icons.

If you wish to have an accurate network diagram, you need to understand the underlying topologies of the network. Topologies refer to how different network components are arranged. Based on this, we can categorize network diagrams.

Logical vs. Physical Network Diagrams

Irrespective of how sophisticated they are, network diagrams can either be logical or physical. This categorization concerns how various devices are arranged in a network.

Logical Network Diagrams

These are the most commonly used diagrams by network administrators since these diagrams provide information about the flow of data in a network. This depicts how devices communicate with one another and how information flows through a network. Components like subnets, network objects and devices, routing protocols and domains, voice gateways, traffic flow, and network segments are typically displayed here.

Physical Network Diagrams

As the name implies, this shows the physical arrangement of a network. In a sense, it is similar to that of a floor plan. All physical aspects including cables, ports, racks, servers and any other hardware or devices are displayed in these diagrams. This view helps administrators get a bird’s eye view of all that is happening in a network.

Network Topology Diagrams

The arrangement of physical or logical elements in a network is known as topology. There are different derivations of topology in a network. Some of these derivations are better applied for logical diagrams while others are better for physical diagrams.

Let’s check out some of the common topologies used in network diagrams and the type of mapping best suited for them.

Bus Topology Diagrams

This is also known as the linear topology diagram and is the simplest one on the list. Here, all devices are connected with the help of a single cable, also known as a bus. Although this is easy to set up and inexpensive, the entire network is vulnerable to a shutdown without any prior warning. Hence, it is ideal for small networks with a limited number of devices.

Ring Topology Diagrams

In this network topology diagram, devices are connected in a circular model in the shape of a ring. During data transmission, the packets travel through the ring to reach their destination. While bi-directional ring topologies are possible, most ring networks are unidirectional – meaning data packets can travel in only one direction. This is still vulnerable to total network shutdown even if one workstation is impacted.

Star Topology Diagrams

This contains a central hub that connects to all components in a network. Data passes through the hub when transmitted from one device to another. Due to its central management, it is easy to add new devices to the network. Also, it provides better reliability as the shutdown of a single device will not affect the whole network. However, it is still vulnerable to shutdown if the central hub is affected.

Mesh Topology Diagrams

In this type of topology, all devices in the network are interconnected with one another. This ensures seamless distribution of data packets even if one of the devices or connections goes down. This topology is typically used in wireless networks.

Point-to-Point (P2P) Topology Diagrams

This topology connects any two devices in a network with a common link. The devices can be any component in a network. For instance, a workstation can be connected to a router with the help of a cable in this topology.

Tree Topology Diagrams

This hybrid topology resembles the structure of a tree in the way in which the devices are connected. It is one of the simplest models in the sense that it has only one route between any two nodes in the network. It is flexible and easy to scale. Hence, it is widely used in various large networks.
