Network topology refers to the arrangement of the elements of a communication network, including links, nodes, and connections. It can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks. Network topology can be depicted physically or logically, and it is an application of graph theory wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. There are two categories of network topology: physical and logical.
-
Physical topology: This refers to the actual connections, such as wires and cables, of how the various components of a network are connected to each other. Examples of physical topology include point-to-point, mesh, star, bus, ring, tree, and hybrid topologies.
-
Logical topology: This illustrates how data flows within a network. It is independent of the physical connection of the devices and describes the arrangement of networks and the relative location of traffic flows.
Network topology plays a significant role in how a network functions, and it has a direct effect on network functionality. Choosing the right topology can help increase performance, as a properly chosen and maintained network topology increases energy efficiency and data transfer rates. Administrators can use network topology diagrams to determine the best placements for each node and the optimal path for traffic flow. With a well-defined and planned-out network topology, an organization can more easily locate faults and fix issues, improving its data transfer efficiency.
