P2P traffic control method and system

Abstract

The invention provides a P2P flow control method and system, and relates to the field of P2P network application and structure optimization of IP network results. A method for controlling P2P traffic is characterized in that it comprises: when there is no flow resource in the domain, selecting M intra-domain peers requesting the flow resource to obtain the flow resource from N out-of-domain peers possessing the flow resource, At the same time, other peers requesting the stream resources in the domain are temporarily suspended to obtain the stream resources from the peer outside the domain, M is the minimum number of peers satisfying the P2P application, and N is the number of fragments of the resource stream; and After the M intra-domain peers requesting the stream resources have been acquired, other peers in the domain requesting the stream resources acquire the stream resources from the acquired intra-domain peers. The invention can quickly expand the number of Peers in the domain, so as to localize P2P traffic more effectively.

Description

technical field [0001] The invention relates to the field of structural optimization combining P2P (peer-to-peer, point-to-point) network applications and IP networks, in particular to a P2P flow control method and system. Background technique [0002] The current P4P (proactive network provider participation for P2P) research in the industry mainly considers how P2P applications select Peer nodes based on network topology information and actual network load information, so as to localize P2P traffic as much as possible. These studies can be based on the fact that there are considerable peers in the domain and outside the domain. Through the interaction with the IP network system, the P2P application uses the logical topology information fed back by the IP network system to select as many peers in the domain as possible; or if the number of peers in the domain cannot meet the requirements of the P2P application download The minimum required Peer limit, select a Peer from out...

AI Technical Summary

Problems solved by technology

For example, under normal circumstances, when a hot P2P application first becomes popular, the number of peers in a certain domain must be limited, so a large number of resources still need to be obtained from outside the domain

In addition, the underlying IP network may be underutilized for organized downloads to more effectively reduce out-of-domain P2P traffic
