METHOD, APPARATUS AND SYSTEM FOR ANSWERING REQUESTS ON PEER-TO-PEER OVERLAY NETWORK

摘要

A method, an apparatus, and a system for answering requests in a Peer-to-Peer (P2P) overlay network are disclosed. The method includes the following steps: the destination peer receives a request that carries an address of an intermediate peer, processes the request and generates an answer, and sends the answer to the intermediate peer according to the address of the intermediate peer in the request; and the intermediate peer forwards the answer to a peer that sends the request. The technical solution under the present invention solves the problem of Network Address Translation (NAT) in semi-recursive routing mode on a P2P overlay network.
