Method for realizing P2P stream media system based on bandwidth guaranty technique

Abstract

The invention discloses a method for realizing a P2P streaming media system on the basis of bandwidth guarantee technology, which comprises the step that a data sending terminal sets priority for a request for downloading in time sequence, wherein, on the premise that the data supply capability of the data sending terminal is unknown, the method also comprises the steps that: the data sending terminal directly supplies data for data receiving terminals with high priority; the data sending terminal detects actual average sending speed V1 in 2-5 seconds; when V1 is detected to be less than a normal speed continuously for 2-4 times, the data sending terminal is determined to reach the maximum data supply capability; otherwise the steps are repeated until the data sending terminal reaches the maximum data supply capability. The method of the invention saves external detection resources, reduces mutual effects of sharing networks, is good for maximum utilization of the bandwidth, shortens the time for searching data sources, improves efficiency and provides strong guarantee for stable playing of peer streaming media.

Description

technical field [0001] The invention relates to a method for realizing streaming media, more specifically, relates to a method for implementing a streaming media system by improving P2P technology by means of optimizing server data provision. Background technique [0002] 1. P2P streaming media technology introduction [0003] The current P2P streaming media technology is paid attention to by people. Its main usage methods include software loading, server-side information registration, obtaining media resource information, and realizing interconnection, data transmission and further buffered playback. This technique has two advantages: [0004] a. It does not require the support of Internet routers and network infrastructure, so it is cost-effective and easy to deploy; [0005] b. Streaming media users not only download media streams, but also upload media streams to other users. Therefore, this method can expand the scale of user groups, and more resources will be brought...

Problems solved by technology

[0014] 3. The problem of p2p streaming media transmission

As we all know, the stability of network bandwidth cannot be guaranteed by anyone, so first of all, the accuracy of this approach is questionable, and secondly, there is also a problem with the ratio of uplink bandwidth to downlink bandwidth, and it starts to download (upload / download ) such a piece of data, the bandwidth consumption is relatively large

For the peer side of p2p technology, the original bandwidth is very limited, and then this kind of meaningless consumption, the efficiency at the beginning of the startup should be relatively poor
