METHOD, EQUIPMENT AND SYSTEM FOR UPDATING ROUTING TABLE AFTER NODE FAILURE IN PEER-TO-PEER NETWORK

摘要

A method for updating routing table information after a node fails in a P2P network is disclosed herein. The method includes: the range of the nodes whose route is directed to the failed node is determined according to the distance between the failed node and the neighboring node of the failed node; the failure information of the failed node is sent to the LDN of the failed node within the node range; and the LDN updates the routing table according to the failure information. A network device and a P2P communication network are also disclosed herein. The embodiments of the present invention enhance the capability of the whole P2P network in perceiving node chum and improve the route search efficiency and system stability of the whole P2P network.
