DETERMINING THE NETWORK TOPOLOGY OF A COMMUNICATION NETWORK

摘要

A network management agent, device or module determine the network topology of a communication network based on at least one neighbor network or end device identity and corresponding network link communication delay collected from, determined by, and stored in a Management Information Base of, at least one first network device of the communication network. Neighbor identities and communication delays are determined according to the IEEE 1588 standard.

主权项

1. A method for determining the network topology of a communication network including at least one first network device connected through at least one network link to at least one neighboring network device, the at least one first network device and the at least one neighboring network device being synchronized according to the IEEE 1588 standard, the method comprising:
determining, by each of the at least one first network device, an identity of the at least one neighboring network device and a communication delay of the at least one network link, respectively; and collecting, by a network manager, the respective determined identity and communication delay, and determining a network topology of the communication network including a length of the at least one network link therefrom.
