A method for obtaining seed information and supernode and common nodes in P2P network

Abstract

The invention discloses a method for obtaining seed information, which is applied in streaming media playing of P2P network which includes a proxy server, a background server, a super node and a normal node. The method includes that: the normal node conducts a streaming media program on demand request or a seed information inquiring request toward the connected background server; the background server returns the super node or super node and normal node seed information corresponding to the streaming media program; the normal node stores the returned seed information and conducts connection requests toward various seeds; when the normal node requests for connection with super node seeds, the super node seeds return information of other seeds that are in connection at present with the normal node; the normal node adds the information of other nodes to the seed information stored locally and updates the seed information stored locally. The invention also discloses a corresponding super node and a normal node. Through the invention, the quantity of seeds obtained is increased and the network transmission resource is fully utilized.

Description

technical field [0001] The present invention relates to a P2P (Peer to Peer) network, in particular to a method for acquiring seed information and corresponding super nodes and common nodes in the P2P network. Background technique [0002] From the point of view of member node management, P2P network mainly has two types: client / server (C / S) mode and complete P2P mode. [0003] In the C / S mode, the server has global user information. When a user searches for other users, the server will select from the global scope. The structure is stable, the search efficiency among member nodes is high, and a relatively balanced effect can be achieved. However, a server The number of supported users is limited. When there are a large number of user groups, it is necessary to set up multiple servers in the network, and each server manages some user information. In this way, it is necessary to share user information between multiple servers, and because the online user client It is dynamic...

Problems solved by technology

[0012] The present invention provides a method for obtaining seed information and corresponding super nodes and ordinary nodes, in order to solve the existing in the prior art in the P2P network streaming media transmission process In the middle, due to the small amount of seed information obtained by nodes, the utilization rate of network resources is low
