面向跳播优化的P2P视频点播系统
Skipping optimization for P2P video on demand system
摘要
Abstract
A new video on demand system is designed. It is based on P2VoD algorithm, and it makes changes and optimization for the inadequacies of P2VoD. New system combines tree topology and mesh topology, realizes actions of peers such as joining, skipping, and leaving, especially makes a special optimization for skipping behavior of users and reduces the delay jitter of the system. After the simulation, results show that with the same network load, the initial delay of peers is 20%smaller than P2VoD, while the system is more stable than P2VoD and realizes the skipping function, and the average skipping delay is about 50% of the initial delay.关键词
