Abstract:

A large amount of redundant network traffic in Overlay is generated because the problem of topology mismatching between the physical network and the Overlay network. In order to alleviate the effect of topology mismatching, this paper proposes an Overlay matching method based on the peer relative posi tion information. The core idea of this method is compare the similarity of the route from the peer to be joined to the server with a fixed IP address with other routes from the joined peers to the server,and deduce the peers adjacent to the peer to be joined. The policy of choosing neighbor peers is based on the physical network information, so the topology mismatching problem can be handled efficiently. The experiment shows the constructed Overlay matches the physical network well.

Key words: Overlay construction, topology mismatching, relative position, route matching
