Description
Technical field
The present invention relates to the application of computer network, relate in particular to computer peer-to-peer network (Peer-to-Peer, write a Chinese character in simplified form P2P) application, the interleaving techniques application that belongs to computer network, Distributed Calculation and theory of games, be mainly used in passing through incentive mechanism, promote (the Internet Service Provider of ISP, write a Chinese character in simplified form ISP) and peer-to-peer network service provider (Peer-to-Peer Service Provider, write a Chinese character in simplified form PSP) between cooperation, thereby optimize the peer-to-peer network application traffic.
Background technology
Peer-to-peer network is a kind of distributing network techniques based on equity, and the node in network is client computer, is again server.The peer-to-peer network technology all has a wide range of applications in fields such as file download, Streaming Media, instant messages.But, peer-to-peer network is applied in when enriching network application constantly, also the network bandwidth of 50-90% on consumption network, very large to the impact of ISP, and peer-to-peer network is used growing huge flow becomes its bottleneck that further develops of restriction.
Fact proved that ISP uses simple plugging effect to peer-to-peer network not satisfactory, ISP has been by having alleviated to a certain extent in flow optimization system of network internal administration and caching system the pressure that the peer-to-peer network flow brings, but peer-to-peer network application service and development are exerted a certain influence.The main cause that peer-to-peer network produces huge flow is the logical network topology of application layer and the mismatch of router level network topology, has caused the resource of poor efficiency to use.The flow of optimizing peer-to-peer network becomes the unique channel that solves tight relationship between peer-to-peer network service provider and ISP.
The mode that peer-to-peer network service provider and ISP begin to attempt cooperating is come the use of Optimizing Network Resources, the service of network topology and state information namely is provided by ISP, and the peer-to-peer network service provider optimizes its topological sum data dispatch by accessing above-mentioned service.
Current peer-to-peer network flow optimization mainly comprises following several respects technical scheme and standard:
(1) the flow optimization scheme of Deutsche Telecom laboratory proposition.This scheme thinks that localized peer-to-peer network flow is the key of optimizing peer-to-peer network flow and performance.For localized peer-to-peer network flow, this scheme need to be collected the topology information of ISP's network, and then using to peer-to-peer network according to these information provides the node matching suggestion.When selecting neighbours or downloading data, this scheme sorts to both candidate nodes according to network topological information when the peer-to-peer network client, helps the peer-to-peer network client to select more excellent node.
(2) the flow optimization scheme of network laboratories of Yale proposition.This scheme be one flexibly, the application framework of lightweight.Its main thought is to open explicit communication interface between peer-to-peer network application and ISP, the peer-to-peer network client can call this interface and obtain the network information, or request bearer network allocation of network resources, thereby can more effectively utilize Internet resources, and promote the peer-to-peer network application performance.
(3) application layer traffic is optimized draft standard (Application-Layer Traffic Optimization writes a Chinese character in simplified form ALTO).The target of this standard is: the service that design and standard application layer traffic are optimized, these services can provide more information to carry out nonrandom node to application and select, information will average out between various parameters according to different application and demand, such as maximizing bandwidth resources, minimize cross-domain flow, minimumization node expense etc.And application and demand will be with actual Operation Network as a reference.
(4) some flow optimization schemes of domestic proposition.The peer-to-peer network flow optimization technological frame based on the bearer network perception of the Ministry of Industry and Information Technology's issue, peer-to-peer network flow optimization based on the bearer network perception realizes with the net mate service, and its net mate service major function entity comprises bearer network informant, net mate server, net mate service discovery server, net mate services client etc.This technological frame has become the China's communications industry standard.In addition, Chinese Academy of Sciences's acoustic investigation institute's high performance network laboratory proposes a kind of Managed Solution of peer-to-peer network flow optimization: mainly comprise peer-to-peer network Redirect Server, peer-to-peer network caching server and three entities of domain name resolution server.
Yet, there is certain risk based on the cooperation of peer-to-peer network and ISP, ISP and peer-to-peer network service provider although optimize flow, reduce peer-to-peer network user's service quality for number one.Such as: the Resources list that (1) ISP is leading, poor service node is served may to provide some local service qualities to the peer-to-peer network application, and shields the service node preferably that other ISPs provide.(2) the Resources list of dominating of peer-to-peer network service provider, may due to from different ISPs between cooperation interests different, provide the peer network node that is beneficial to it to the peer-to-peer network client node, and shield some service nodes preferably.(3) in addition, some due to ISP and peer-to-peer network between using are opaque, or some between ISP are opaque, cause the problem of some service quality.
Exist general uncooperative problem in peer-to-peer network, and the uncooperative overall utility that has a strong impact on peer-to-peer network between node, it has caused negative effect to network robustness, availability and life cycle etc.Design, the rational peer-to-peer network flow optimization mechanism of application are important directions of current peer-to-peer network research.Therefore, the effective incentive mechanism of design promotes the cooperation between node to have very important significance.
