摘要
由于P2P网络的动态性、分散性和半可信性,其实时性研究和应用成为公认的难题。当前P2P多媒体应用系统和实时计算系统或多或少采用了实时保障措施,但均没有对P2P实时性进行系统研究。在总结现有P2P网络系统采用的实时技术的基础上,分析了P2P网络结构、搜索协议(算法)和任务调度对实时性的影响,提出P2P网络实时性研究存在的问题,总结出P2P实时性研究需要解决的关键技术。
However,due to the instability, decentralization and semi-trust of the peer-to-peer network,real-time research is a well-known difficult problem. Though many measures had been applied to deal with this problem, there was no systemative research of real-time performance. This paper summarized the real-time technology of P2P network in the past few years, then analyzed the relationship between real-time performance and P2P network architecture, searching protocol (algorithm) , task scheduling. In the end, put forward the remaining difficulties and key technologies of real-time performance.
