Algorithms of topology discovery for remote networks in different management domains

The common technology of the network discovery can only fulfil the local management work and can not fulfil the remote topology discovery of networks.A class of rules of the network topology analysis was advanced.Based on it,an algorithm of remote network discovery covering different management domains was presented.This algorithm can resolve the problem of no longer connected graph in the discovery for different management domains and fulfil the demand of accuracy and integrity in the topology discovery.The test effect in CERNET in east China was given and analysed.
