Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0036] This application mainly proposes a network topology optimization mechanism on a peer-to-peer network platform, which is mainly established on a peer-to-peer network whose main function is resource sharing. Based on the introduction of capability clusters and interest clusters in peer-to-peer networks, a scheme to optimize network topology by using "wanderers" is designed.

[0037] In a typical peer-to-peer network, all nodes are divided according to their relationship to resources, which can be divided into resource providers and resource demanders. The former provides service ...

Abstract

The invention relates to a P2P network optimization method based on floating packages. The method includes: a resource publishing node sends a positive floating package including a specified resource identifier to adjacent nodes thereof with a first set sending rate and sends a negative floating package including the specified resource identifier to the adjacent nodes thereof with a second set sending rate, wherein the positive floating package and the negative floating package are information packages including resource publishing node information, and the negative floating package is an information package including resource demand node information; and any node in the network receives the positive floating packages and the negative floating packages in the network, matches the positive floating packages and the negative floating packages when receiving the positive floating packages and the negative floating packages including the same specified resource identifiers, establishes a network connection between the resource publishing node and the resource publishing node respectively corresponding to the positive floaitng packages and the negative floating packages, and forwards unmatched positive floating packages and negative floating packages to the adjacent nodes. Compared with the prior art, the method is advantaged by wide application range.

Description

technical field [0001] The invention relates to a network connection technology, in particular to a wanderer-based P2P network optimization method. Background technique [0002] Currently commonly used P2P network protocols include: Gnutella, BitTorrent, Kademlia and so on. [0003] Gnutella is a P2P networking protocol commonly used in the early days of the Internet, which defines the way computers communicate with each other in a completely decentralized network environment. Gnutella is decentralized. This means that the existence of the network does not depend on some central company. Gnutella's clients are connected to each other, and there is no central server. Its defects are: 1. The security of resources cannot be guaranteed; 2. It lacks some necessary central coordination. [0004] BitTorrent is a content distribution protocol. It uses an efficient software distribution system and peer-to-peer technology to share large-volume files, and enables each user to provi...
