摘要/Abstract

摘要：提出了一种大规模流媒体分发系统设计思路.首先，分析网络和节点异构性对流媒体传输的可信和可靠需求，构建出大规模、复杂网络环境中可信流媒体分发系统拓扑结构；然后，研究动态系统环境下能保证流媒体服务质量和各种粗细粒度调度方法，设计出自适应网络节点异构性的数据调度策略和算法；接着，研究面向流媒体的网络测量方法，基于实时流媒体传输质量的评估，提出了自适应流媒体传输调节的方法；最后，分析了流媒体系统提供服务的机理，确定系统的状态信息和关键数据，分析各种故障和攻击情况下系统的可用性，提出了流媒体传输故障检测方法和系统恢复方法.

关键词： 流媒体系统, 自适应, 调度算法, 调节方法, 故障检测, 系统恢复

Abstract: To obtain a credible and reliable streaming media system,this paper firstly analyses various possible network topologies,as well as different size data scheduling methods and their impacts,and presents an adaptive scheduling algorithm for different heterogeneous networks.Next,this paper studies real-time streaming quality assessment methods,and designs adaptive streaming adjustment method based on its results.In addition to this,according to the system state information and key data obtained,this paper analyses the system availability under various faults or attack conditions,then designs appropriate fault detection and system recovery method.Finally,the system implementation method to construct a large scale real-time reliable streaming media system is presented in this paper.

Key words: credible and reliable streaming media system, adaptive scheduling algorithm, adaptive streaming adjustment method, fault detection and system recovery method
