Example Embodiment

[0077] Example:

[0078] The peer-to-peer network organization method for classified retrieval described in the present invention can be illustrated by specific examples. The experimental environment includes 1 index server and 10 ordinary PCs, and the cache capacity of each PC is 30MB. The hardware configuration of the PC is as follows:

[0079] machine name

[0080] PCs 1-10 are referred to as node 1, node 2...node 10, respectively. At a certain moment, the peer-to-peer network classified according to the supernodes of node 1 ... node 9 is shown in Fig. 5 . According to the hardware configuration of the system, the upper limit value of the "neighbor" nodes in the system is set to 4, the lower limit value is 2, the life cycle of each information is 3, and the communication cycle of each information is 30 seconds.

[0081] When node 10 joins, it first sends the supernode category A that it will join to the index server (tracker server), and the index server querie...

Abstract

The invention discloses a network organization method of systematic searching in a peer-to-peer network video sharing system; each node executes the following steps: (1) the super node list and the neighbor list are initialized; (2) the self-attached super node pattern is decided, and similar super node list is decided from a super node index server; (3) that whether the contact ratio of the index of the nodes of the super node list and the index of the node is smaller is judged; (4) the nodes of small index contact ratio in the super node list is added to the neighbor node list; (5) that whether the interval of the current information sending and the last information sending reaches the exchange cycle is judged; (6) update information and topological maintenance information between the super node and the neighboring node is exchanged; (7) that whether an exit request is received is judged. The method of the invention uses the super node to judge the attached pattern of the node, and adds the node of small index contact ratio in the category to the neighbor node. The method is characterized by quick index speed, stable network topology structure, self-adaptive adjustment based on the interests of the user.

Description

technical field [0001] The invention belongs to the field of computer application and relates to the cross field of the combination of peer-to-peer network and streaming media technology, in particular to a network organization method for classification and retrieval in a peer-to-peer network video sharing system. Background technique [0002] In the field of Internet streaming media, in response to the limited service capability of the traditional Client-Server model, peer-to-peer network technology has developed rapidly due to its strong scalability, low server dependence and low system cost. Popularization provides a good technical foundation. The streaming media application based on the peer-to-peer network enables the nodes to share the existing data with each other without having to focus on the video server to obtain the data, thus greatly reducing the burden of the video server and the network. [0003] The design of the existing streaming media system based on peer...
