Embodiment Construction

[0022] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of a network architecture of an application scenario of an embodiment of a method for establishing a P2P peer-to-peer connection in the present invention. exist figure 1 In the shown network architecture, access routers 1-4 (AccessRouter, referred to as AR) are connected to each other in the network, P2P client 1-4, P2P server and authentication, authorization and accounting (Authentication, Authorization, Accounting, referred to as AAA) servers are interconnected through AR1-AR4 in the network. These connections are logical connections.

[0024] In the above network architecture, P2P clients 1-4 are all terminals capable of providing P2P services, and can be located in computing devices such as PCs and notebooks or mobile terminals such as mobil...

Abstract

The invention relates to a peer-to-peer (P2P) establishment method. The establishment method includes the steps of receiving a P2P establishment request of a P2P client-side by a P2P server, sending an inquiry request to an authentication, authorization and accounting (AAA) server by the P2P server according to an internet protocol (IP) address of the P2P client-side, returning a geographical doorplate address inquired by the AAA server to the P2P server, updating an address mapping table which is stored by the P2P server by the P2P server and searching at least one IP address of a P2P opposite terminal relative to a torrent file, inquiring the geographical doorplate address corresponding to the IP address of the P2P opposite terminal in the address mapping table, selecting a coincident client-side of the P2P opposite terminal according to a nearby distance strategy, forming a P2P opposite terminal group and returning the P2P opposite terminal group to the P2P client-side so that the P2P client-side conveniently establishes P2P with the client-side of the P2P opposite terminal group. Due to the fact that the P2P is optimized according to physical location information, nearby connection between the P2P opposite terminals is achieved, and therefore stability of the P2P is improved, and utilization efficiency of network bandwidth is improved.

Description

technical field [0001] The present invention relates to the field of Internet communication, in particular to a peer-to-peer (PEERtoPEER, P2P for short) peer-to-peer connection establishment method and system. Background technique [0002] With the development of Internet technology, the application of P2P services in the Internet has been very extensive. When the client uses the P2P service, it will obtain the IP address list of other PEERs from the Track server through the seed file, and then try to establish multiple concurrent Transmission Control Protocol (TCP) connections with other PEERs according to the obtained IP address list. to upload and download data. [0003] Among the TCP connections established by the clients, there are clients belonging to the remote end of the network. The stability of the connections of these clients is greatly affected by changes in the network topology and traffic, and they also occupy more network resources. Contents of the inventio...
