Problems solved by technology

However, the currently available IP tables usually cannot guarantee correctness and comprehensiveness, and maintaining an IP table that changes over time is usually not an additional expense that a P2P project is willing or able to bear
Therefore, this method is difficult to apply in practice, and the IP table is not satisfactory in terms of subnet classification, and it is powerless to locate the local area network.

Embodiment 1

[0034] The peer selection system in the peer-to-peer network proposed by the present invention, its first preferred embodiment is as follows figure 1 shown, including:

[0035] A peer selection system in a peer-to-peer network, characterized in that it includes:

[0036] A routing table acquisition module, the routing table acquisition module acquires the routing table from the client to the preset server according to the routing request sent by the client to the preset server;

[0037] Routing table processing module, the routing table processing module classifies the IP address of each hop in the routing table according to the routing table of the client, and stores the client into the corresponding group according to the classification;

[0038] The peer selection module selects the closest group as the peer of the client for point-to-point transmission according to the required number of peers.

[0039] The peer selection system in the peer-to-peer network proposed by th...

Embodiment 2

[0041] The second preferred embodiment of the present invention is improved on the basis of the first preferred embodiment, that is, the routing table processing module includes:

[0042] Search submodule, the search submodule searches the routing table of the client, and judges whether the IP is routed by the national backbone network in the routing table; if there is, the routing IP of all hops after the first national backbone network routing IP is deleted , and classify according to the reserved routing IP; if not, add the provincial backbone network routing IP and the national backbone network routing IP in the routing table, and classify according to the routing IP;

[0043] Group sub-module, the group sub-module is provided with multiple groups, each group has different levels, and stores the client with the same routing IP; the client will be stored according to the routing IP of the client to the group.

[0044]The second preferred embodiment of the present invention...

Embodiment 3

[0046] The present invention proposes a peer-to-peer selection method in a peer-to-peer network, and the flow of its preferred embodiment is as follows figure 2 shown, including:

[0047] Step 1, the client sends a routing request to the preset server to obtain the routing table from the client to the preset server;

[0048] Step 2, classify according to the IP address of each hop in the routing table, and store the client in the corresponding group according to the classification;

[0049] Step 3. According to the required number of peers, find peers from the closest group as the peers of the client's point-to-point transmission.

[0050] The peer selection method in the peer-to-peer network proposed by the third preferred embodiment of the present invention can classify clients hierarchically according to the routing table. The method of the present invention can obtain the network structure where the client is located through the routing table, so that when the point-to-...

Abstract

The invention provides a system and a method for selecting opposite terminals in a point-to-point network, which aims to solve the problem that high-quality opposite terminals cannot be selected in the prior art. The system of the invention comprises a routing table acquisition module, a routing table processing module and an opposite terminal selection module. The method comprises the steps that: sending a routing request to a preset server by a client to acquire a routing table from the client to the preset server; classifying according to an IP address of each jump in the routing table and storing the client into a corresponding group according to the classification; and searching for opposite terminals in an approximate group as the opposite terminals for the point-to-point transmission of the client according to the required number of the opposite terminals. The system and the method can search for the opposite terminals in the approximate group as the opposite terminals for the point-to-point transmission of the client according to the required number of the opposite terminals by acquiring a series of group tables. The device and the method of the invention can improve the transmission property of the P2P network.

Description

technical field [0001] The invention relates to a peer-to-peer network technology, in particular to a system and method for peer selection in the peer-to-peer network. Background technique [0002] With the development of P2P (Peer to Peer, peer-to-peer) network transmission technology, many strategies for optimizing peer (point) selection and improving peer quality have emerged. [0003] In the field of P2P network transmission technology, "high-quality peer" can obtain better data transmission rate and stability. Among them, "a high-quality peer" can be approximately equivalent to efficient network transmission between the peer and the client requesting the peer, so it can be seen that a high-quality peer has great relativity. [0004] Due to the physical factors of network construction and the regional factors of the current network operation in China, the quality of peers in the practice of China's P2P network transmission technology has the following characteristics: ...
