Problems solved by technology

The above-mentioned peer-to-peer network software and method are implemented either through the P2P server of the telecommunications company in the form of ASP or through the enterprise's own P2P server in the IDC of the telecommunications company. The burden on the server cannot be completely separated from the server, and it cannot penetrate firewalls and NAT routers, and there are also trust and security issues

Embodiment Construction

[0015] The steps to establish a peer-to-peer network between entities (peers) are as follows: figure 1 Shown: (1) Entity A newly connected to the network sends a notification message to one of the entity B in the online entity list through the UDP port, indicating that entity A is online; (2) Entity B receiving the information Return a response to the entity A that sent the information, confirming the receipt of the information and asking entity A to authenticate entity B, and at the same time send a data packet to it, the content of which is the name of all online entities that entity B knows. During the authentication process, both entity A and entity B exchange secret information with a shared key; (3) after entity A authenticates entity B, it adds the received list to entity A's online entity list and requires entity B to authenticate Entity A; (4) After Entity B authenticates Entity A, Entity A is added to the entity's online entity list, and Entity A is authorized to acc...

Abstract

A peer-to-peer network is based on TCP / IP protocol to form logic network of layerless structure between abstract peer-to-peer entities in completely equal status, each entity can be a server providing service to other entities or customer end served by other entities, the concrete way of realizing and entity is specific software example operating on computer or special information terminal equipment. This method can realize centerless exchanger of no center server light burden peer-to-peer network status, any fire-proof bulkhead of NAT router, any entity log on to net can know if other coherent entities are online at once by certification and inform on-line entities about its no-line information.

Description

1. Technical field [0001] The invention relates to the field of network and communication technology, and in particular to a method for realizing a peer-to-peer network architecture. 2. Background technology [0002] The so-called peer-to-peer network (P2P, peer-to-peer) is a technology used to directly exchange data or services between different PC users without going through a server. It allows Internet users to directly use each other's resources or communicate directly. Each networked user can directly connect to other users' computers and exchange data without connecting to the server for browsing and downloading. Peer-to-peer network technology makes communication on the network faster and more direct because of the elimination of intermediate links. [0003] At present, the software that can realize peer-to-peer network technology includes Napstere and ICQ in foreign countries, and OICQ and Ezpeer in China. The specific operation mode of Ezpeer is as follows: First, ...
