What is Topology of Network

The shape or layout of the topology network is called. How different nodes of the network are connected to each other and how they establish communication with each other, the topology determines that network, topology is physical or logical.

The method connecting computers and data flow in it is called topology. Topology is the geometric arrangement of computers in a network.

Types of topology

Ring topology

There is no host, main, or controlling computer in this computer. All the computers are engaged in a circular shape, each computer is connected to its subordinate computer, owner in it. it is also called circular.

Bus topology

Bus topology uses the same wire (Cable) and all computers are connected to the same wire in the same sequence. A special type of plant is called a terminator. The signals.

Star topology

In this network, there is a host computer that is directly connected to various local computers. Local computers are not connected, they are connected by the host computer. The entire network is controlled by the host computer itself.

Mesh topology

Mesh topology is also called mesh network or mesh. Mesh is the network topology in which plants are connected between network nodes by many additional interconnections. That is, each node in the mesh topology is connected to all the other nodes of the network.

Tree topology

Tree topology the characteristics of both star and bus topologies are present in the tree topology. It has a host computer like star topology and like bus topology, all computers are connected by a single cable. This network looks like a tree.

Hybrid topology

The hybrid topology is any combination of two or more topologies, hybrid topologies typically provide exceptional flexibility, as they can accommodate several setups.

A logical topology for a network refers to the relationship between nodes and logical connections. Defining how data should transfer.

A logical connection differs from a physical path when information can take an invisible (hop) at intermediate points. In optical networks (optical add-drop) multiplexers create a logical optical path because the ADM hop is not visible to the endpoint nodes. Networks based on virtual circuits or tunnels have a physical topology based on the real connection medium fiber, for example- and the logical topology based on the circuits and tunnels.

The logical topology refers to the topology as the user sees it. (Internet protocol) IP and the Ethernet networks are two common examples. They have fully meshed at the connections level since any user connects with any other user. This is true unless some means of blocking unwanted connections, like a firewall is of the network protocols used (IP and Ethernet) not of the network topology itself.

       Why is network topology important?

Network topology plays a major role in network functions. The topology has a direct effect on the network functionality choosing the right topology can help increase and maintain network topology increases energy efficiency and data transfer rates.

Network topology makes it easier for the network admits to locate faults, troubleshoot issues, and allocate network resources, diagrams are an impotent reference point in helping to diagnose network issues, as they can represent physical and logical layouts.

The examples of network topology tools and software

There are many network topology tools available, including those that can be categorized as configuration and management tools, networks performance software, and network mapping software.

Network configuration software helps configure networks, while also automating repetitive tasks. These tools are often used to configure complicated network topologies and can auto-detect networks nodes and highlight apparent vulnerabilities.

 The Network topology performance are monitoring and troubleshooting tools that keep track of and alert users to network-related performance issues and outages, some of these tools may keep track of performance using a visual display of the network topology, After setting baseline performance setting, users can track, locate and troubleshoot issues.

Network topology mapping software aids in creating network topology diagrams. Examples of mapping tools and features are the following

  • Data dog lives network mapping.
  • Edraw
  • Manage Engine op manager network mapping
  • Microsoft Visio
  • Spice works networks mapping 
  • Solar winds network topology mapped
  • Lucid chart
  • Nattering logical

  The configuration is selected network topology design software network configuration management tools, and network management software solution aid not only in building network topology but also in automatic configurations, continuously monitoring performance and troubleshooting network issues.
