摘要：
Mismatching between overlay and physical network in structured p2p system leads to overlap of links crossed on backbone network thus it brings link waste and congestion. A method used for detecting and resolving the link overlap problem is proposed in this paper. It introduces TTL as the measurement of distance, and adjusts the routing table of node according to redirect message achieved from TTL calculation and comparison. This method is protocol-independent and easy to be built on any structured P2P system. It avoids the inaccuracy problem that the time latency or IP information method contained. Through illustration, it is proved to indeed decrease the number of links crossed in routing procedure, thus resolves the waste of link bandwidth and useless flow over the backbone network brought by mismatching problem.
