[0093] Optimized P2P access strategy

[0094] If the P2P traffic can be limited to the edge of the network as much as possible, the bandwidth pressure of the backbone network can be effectively reduced. Therefore, the P2P access mode is transformed, and the following new download strategy is adopted:

[0095]When a node wants to download a certain resource, if other computers under the building switch own the resource, it only downloads from the computer under the switch of the building; otherwise, if other computers in the community network own the resource, it only downloads it from the The computer in the community network downloads; otherwise, if other computers in the access network own the resource, only download from the computer in the access network; otherwise, if other computers in the convergence network own the resource, Only download from the computers in the converged network; if none of the computers in the converged network has the resource, download it to ano...

Abstract

The optimization method for P2P application in MAN comprises: a. when requiring downloading some resource, calling this P2P node as the request P2P node; b. searching the P2P index server to find out the P2P node list included the target resource, and calling as resource P2P node; c. from resource P2P node list, finding out the one with shortest distance with the request P2P node; and d. downloading target resource from one or more resource P2P nodes. Compared with prior art, this invention limits P2P flow on network edge as far as possible, can avoid network congestion led by P2P business, and fit to spread widely.

Description

technical field [0001] The invention relates to a network transmission optimization technology, in particular to a method for reducing network backbone bandwidth occupation and preventing network conflicts in the P2P application of the metropolitan area network. technical background [0002] P2P is an important technology in network transmission at present, and it provides new technical support for realizing network resource sharing. P2P technology obtains higher transmission performance by using the network bandwidth as much as possible, so it is rapidly popularized in network applications. Compared with the traditional client / server model, P2P technology realizes the distributed storage and sharing capabilities under the peer-to-peer network. Each node computer is not only a client for downloading to other nodes, but also a storage server. Nodes share their storage content, so they can provide more massive and richer content, which has become one of the important attracti...
