AI Technical Summary

Problems solved by technology

When the client needs to search for a certain piece of data, it can only search from the beginning of the cache area each time until it finds the target data block, so the buffering process generally lasts for a long time
Moreover, the traditional linear cache data structure is not conducive to data sharing and transmission during frequent data exchanges between clients and between clients and servers.

Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings of the embodiments.

[0025] The invention supports discretized cache data block management by processing cache data, can be broken into parts, speeds up data search, and improves data management efficiency. In order to meet the needs of users to skip video on demand, users can enjoy the fun brought by network audio and video. At the same time, when data is shared between clients, the required data can be quickly found.

[0026] figure 1 It is an analysis diagram of the cache structure in the prior art. This data structure is used for data contiguous linear cache.

[0027] In order to improve data management efficien...

Abstract

The invention provides a method for processing p2p (peer-to-peer) cache data. Aiming at p2p cache data, data is divided into a plurality of cache data blocks on the aspect of logic, the cache data blocks are organized in the form of a chain table, and a recording table is used for maintaining the cache data blocks, so that the requirement of a client end for frequent sharing transmission of data in an interval type and jumping type requested broadcasting view manner, between client end nodes, and between a client end node and a server end is met.

Description

technical field [0001] The present invention relates to P2P data cache data, and more specifically, relates to a method for processing p2p cache data. Background technique [0002] In the client of the p2p system, a part of data needs to be cached in the memory. This part of the data is for the client to quickly call when needed, or to be provided to other clients for data sharing between p2p client nodes. When the local client performs intermittent and jumping viewing methods, it can also use the cached data to play without downloading again. And when a client needs certain data, it can be downloaded and used from other clients who have the data nearby, thereby reducing the bandwidth pressure on the server. [0003] The traditional p2p client data cache is a linear cache, such as figure 1 . This kind of linear cache continuously stores data has the disadvantage of low data management efficiency. When the client watches intermittently or skipping, the client needs to buf...
