Logical topology

Physical Topology and Logic Topology are independent. For example: All types of Ethernet communications between the Ethernet are logical bus type topologies, which is the case regardless of the physical layout of the cable.

Physical topology is derived from the actual physical address of the network device, so it is more suitable for network device layer management, through physical topology, once faults in the network or will be faulty The physical topology map can tell the network manager which network device has a problem in time and detail, and a simple example. When a switch in the network is faulty, through physical topology, the network management system can tell the manager. The port of which switch in the network is in the network, and the network devices are connected through this port, which is convenient for network management personnel. For logical topologies, he is more paying more attention to the operating conditions of the application system, which reflects the case of practical applications
