Compensation method of P2P music on-demand system

Abstract

The invention belongs to the technical field of P2P network streaming media, in particular relating to a compensation method of a P2P music on-demand system. The music on-demand compensation mechanism provided in the invention comprises the following steps: compensation is started, and compensation is performed aiming at the condition that music data file playing can not be immediately started; compensation is performed during the playing, and the compensation is performed aiming at the condition that the music playing is started. By adopting the technical scheme in the invention, the playing starting time delay of the music can be reduced, the music playing continuity can be ensured, and the expansibility of the system can be improved, therefore, the waiting time of the user can be shortened, and the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of P2P (Peer-to-Peer, peer-to-peer) network streaming media, and more specifically, to a compensation method for a P2P music on-demand system. Background technique [0002] Music-on-demand applications are becoming more and more popular, but high-quality music requires high bandwidth resources. The traditional C / S mode cannot meet the application requirements, and the server can easily become a system bottleneck; IP multicast transmits audio in a distributed manner through intermediate nodes (peers). Streaming reduces server and network loads, but due to deployment reasons, it is difficult to implement widely on the Internet; CDN uses proxy caching nodes to push services and content to the "edge" of the network, but deployment is expensive and has the same C / S mode Similar bottlenecks; P2P streaming media provides services for other nodes by using the resources of ordinary nodes, and has good cost performanc...

AI Technical Summary

Problems solved by technology

Since the system adopts the P2P mode, it is possible to download the music data with a later playing time first, while the previous music data cannot be downloaded for a long time, thus increasing the start-up delay;

[0006] 2) It is not determined which data really need to be compensated

It may cause too much data or too little compensation. Too much compensation will increase the pressure on the server, making the music source server a system bottleneck and affecting the scalability of the system. Too little compensation will cause the continuous performance of playback to decline, often stagnate, and affect user experience
