摘要
A multicast MPLS networks node in network communication field and a method and a system for fault localization are provided. The method includes a step that a leaf node judges the connectivity of a multicast path; a root node generates a fault localization message to perform fault localization for a fault branch after learning the branch where the fault is located in accordance with the judgment result of the leaf node. An embodiment of the present invention further provides a fault localization system for Multicast MPLS networks, which includes a connectivity checking module, a root node learning module, a node reply module and a fault localization module. The technical solution in the embodiment of the present invention restrains unnecessary message, reduces redundant information, and improves network efficiency by carrying the information of the fault branch in the fault localization message to perform fault localization only for the fault branch.
