Structured P2P based application service platform and implementing method thereof

Abstract

The present invention relates to an application service platform based on the structuring P2P and a corresponding realization method. An automatic group net module comprises a DHT group net, a RON group net and an API function. The DHT group net organizes the nodes in a network according to the manner of structuring P2P to provide neighborhood relation between the nodes for the realization of the API function. The RON group net organizes the nodes according to the geo information such as the autonomy areas where the nodes is and provides the node neighborhood relation for a distributed network measuring module and a route optimization module. The API function realization specifically finishes all functions provided by the API interface to the upper application. The distributed network measuring module obtains the route state information between every node in the automatic group net module, RON group net and the RON neighborhood nodes. The route optimization module provides an optimization route to the data passing through the RON neighborhood. The distributed network measuring module makes arrangements of basic information respectively to the automatic group net, the distributed network measurement and the route optimization module, and obtains all states in the running process of these modules. The API interface achieves the alternation of the upper application and the automatic group net module. The present invention has the advantages of simple structure, easy realization, high efficiency and strong expansibility.

Description

technical field [0001] The invention relates to a structured P2P application service platform and a realization method thereof, belonging to the field of computer network system platforms. Background technique [0002] After several years of rapid development, P2P technology has been widely used in today's Internet. The current applications mainly focus on two aspects. On the one hand, it provides file or metadata storage services, from the centralized music file P2P service Napster to the fully distributed Gnutella, Freenet, and some file sharing systems, such as CFS ( Cooperative FileSystem), PAST, OceanStore, among which Napster is a centralized structure, Gnutella and Freenet use a fully distributed unstructured P2P, while CFS, PAST and OceanStore adopt a structured P2P model that appeared later in P2P. Another aspect of P2P application is streaming media, which uses P2P technology to realize large-scale streaming media live broadcast and on-demand services on the Inter...
