What is the use of network topology? Table of Content What is Network Topology? Computer Network. Scott Justin I am a freelance writer. My areas of interests are very wide, but mostly I write for educational websites, essay writing websites, journals and blogs. My aim is to share innovative ideas with potential audience and provide useful tips for readers.
I used to concentrate on all sorts of academic writing especially with regard to reviews of essay writing service. Your name can also be listed here. Got a tip?

Determining the right topology for your needs, then, is a matter of striking the right balance between installation and operating costs and the level of performance you require from the network.
The last element to consider is scalability. Star topologies are so common because they allow you to add, remove, and alter nodes with minimal disruption to the rest of the network. Ring networks, on the other hand, have to be taken entirely offline for any changes to be made to any of the nodes. They allow you to see how the information will move across the network, which, in turn, allows you to predict potential choke points. Visual representation makes it easier to create a streamlined and efficient network design, while also acting as a good reference point if you find yourself needing to troubleshoot errors.
There are a few network topology mapping products on the market. First, consider using a network configuration management tool. This kind of tool can help you configure your network correctly and automate repetitive tasks to take the pressure off the network administrator. As your organization or network grows, the network topology may become more layered or more complex, and it can become harder to deploy configurations across the entire network with certainty. However, with configuration management tools, the complicated network topology is no issue: tools can usually auto-detect each node on the network, allowing you to deploy standard configurations that may be required for compliance reasons, or flag any configurations outside what is expected.
Network configuration management tools can also highlight vulnerabilities, so you can correct these issues and keep your network more secure. Finally, these kinds of tools should also display the lifecycle of the devices on your network, alerting you to devices coming to their end-of-service or end-of-life points, so you can replace them before problems begin to arise. You should use network management software to track overall performance.
A performance manager can keep track of network issues, outages, and performance issues. A performance management tool will also have the functionality to set network performance baselines and establish a clear picture of how your network typically behaves when healthy.
Then, by setting alerts when your network performs unexpectedly or outside of these baselines, you can quickly track, pinpoint, and troubleshoot issues. With complex network topologies, it may be hard to figure out exactly which part of the network is having issues. Some performance managers will create a visual display of your network topology, so you can see the entire network in a one-map overview. This can show you how your network is laid out, bring your attention to changes in the topology, and flag where problems are arising.
To get started understanding your network topology, you can try a tool like Network Topology Mapper free for 14 days. This tool automatically discovers and generates detailed topology maps of your network and can create multiple map types without having to rescan your network every time.
No matter the size of your network, it can not only automatically discover all the devices and create a diagram of your network topology for you, but also populate the map with industry-specific icons for easy visual differentiation. In addition to the auto-discovery feature, the software offers an intuitive network wizard so you can drag and drop nodes and node groups which you can also customize.
You can configure NTM to periodically rescan your network to keep your diagrams up to date. It integrates easily with other programs, and it offers a robust reporting system so you can track metrics, from device inventory to network performance, all while helping keep you PCI compliant. The N-central network topology mapping solution enables you to perform in-depth assessments of the networks you manage. You can perform on-demand and scheduled scans, as well as get access to detailed data represented in a clear, visual way.
The best advice I can give regarding network topology is that you should be deeply familiar with the needs and usage requirements of your network. For this reason, I would avoid jumping to immediate conclusions about any of the network topologies based solely on the descriptions here. Why Is Network Topology Important? Physical — The physical network topology refers to the actual connections wires, cables, etc.
Setup, maintenance, and provisioning tasks require insight into the physical network. Logical — The logical network topology is a higher-level idea of how the network is set up, including which nodes connect to each other and in which ways, as well as how data is transmitted through the network.

A bus topology with two endpoints is called a linear bus topology. Bus topology is the easiest and cheapest type of topology to install. With a one-to-one ratio of devices to drop lines, this topology requires less cable than other topologies, reducing the installation time and expenses.
Adding new devices to the network is also straightforward. Just connect the new device to the central cable with a new drop line. While having a single cable makes bus topologies incredibly cost-effective, it also introduces several potential problems, including increased collisions, increased congestion, and low security.
As a result, bus topologies are best for networks with low traffic volumes. If the common cable fails, then your entire network will crash. Additionally, as a half-duplex, data can only be transmitted in one direction along the cable at any given time, making congestion a common problem. As more network nodes begin to rely on the main cable, data transmission rates will slow.
Ideal for high-value, small to mid-sized networks, mesh topology consists of interconnected nodes, making it a fast and secure choice. In a full mesh network topology, each node is connected to all the other nodes via direct link, creating point-to-point connections. In a partial mesh topology, most nodes are interconnected, but some nodes only connect with a few others via point-to-point links. Data transmitted within a mesh topology is sent through routing or flooding.
As you might expect, it takes several cables to connect each node to all the other nodes, which means installing mesh topology can get expensive quickly, takes a considerable amount of time to set up, and requires a lot of configuration. Consequently, this topology is difficult to administer and costly to maintain.
