Embodiment Construction

[0026] The P2P flow optimization system of the present invention is to realize the P2P flow guidance in the Internet under the premise of ensuring the user experience of the P2P application, reduce the occupation of the backbone network by the P2P flow, and ensure the propagation effect of other traditional mainstream content, so that Internet business Carry out normally. The present invention will be further described below with reference to the drawings and embodiments.

[0027] 1. The overall network architecture

[0028] The network system for P2P traffic optimization provided in this embodiment needs to deploy a PPR (ie P2P Redirector, the Chinese name is P2P redirection device) for P2P traffic optimization, and the PPRs are all referred to as PPR servers in the following. At the same time, in order to further optimize P2P traffic, this embodiment may also choose to further deploy PPC (ie P2P Cache, the Chinese name is P2P caching device), and the PPC is referred to as a PPC ...

Abstract

The invention provides a P2P traffic-optimized network system which comprises a plurality of levels of autonomous domains, and also comprises a plurality of P2P traffic-optimized domains, wherein each autonomous domain comprises a plurality of P2P nodes, and each P2P traffic-optimized domain comprises an autonomous domain and a P2P redirection device deployed in the autonomous domain; the P2P node is used for sending a resource request to the P2P redirection device of the P2P traffic-optimized domain, and the P2P redirection device is used for receiving the resource request of the P2P node of the P2P traffic-optimized domain, finding target P2P nodes containing target resources within the traffic-optimized domain and returning a target P2P node list to the P2P node sending the resource request; and the P2P redirection device is also used for refusing the resource request of the P2P node of the P2P traffic optimized domain. In the invention, the traffic-optimized domains are built based on the autonomous domains, thereby avoiding the problem that an idealized model is not matched with an actual network environment in the prior art. The invention has the advantages of few devices needing to be deployed, simple deployment and low cost.

Description

Technical field [0001] The present invention belongs to the technical field of computer networks. Specifically, the present invention relates to a network system optimized for P2P traffic. Background technique [0002] P2P is a distributed network that breaks the traditional Client / Server (C / S) model, and the status of each node in the network is equal. Each node not only acts as a server, provides services for other nodes, but also enjoys the services provided by other nodes. However, P2P applications occupy a lot of bandwidth. Statistical analysis shows that P2P applications account for about 50% to 60% (daytime) to 90% (night) of broadband traffic, which makes some important applications (such as Web, E-Mail) service quality Severely affected, it also brings a lot of trouble to operators' network management and increases their operating costs. Therefore, effective management and optimization of P2P network traffic has become an urgent problem in network management. [0003] F...
