(also logical network topology)
Logical topology definition
Logical topology refers to the abstract representation of how data flows and is transmitted within a network, independent of its physical layout. It is the structure that dictates how data packets travel between network nodes and is determined by the protocols and data handling techniques used, such as Token Ring, Ethernet, or wireless protocols. Unlike physical topology, which focuses on the physical connections between network devices, logical topology focuses on the path that data takes as it traverses the network.
Logical topology examples
- Bus: In this logical topology, all nodes are connected to a single backbone or transmission line. Data packets are broadcast to all nodes, but only the intended recipient processes the information.
- Ring: In a ring topology, each node is connected to two other nodes, forming a closed loop. Data packets travel in a unidirectional manner from one node to the next until they reach their intended destination.
Understanding logical topology
- Analyze the protocols and data handling techniques used in your network to determine its logical topology.
- Consider the impact of logical topology on network performance, reliability, and security.
- Regularly review and update your network’s logical topology to ensure optimal performance and minimize vulnerabilities.
