摘要

提出一种适用于移动通信网的两级缓存流媒体系统结构2CMSA(two-level cache mobile streaming archi-tecture)

它突破了移动流媒体系统中终端缓存空间小、无线接入网带宽窄的局限;针对2CMSA结构设计了基于两级缓存的移动流媒体调度算法2CMSS(two-level cache based mobile streaming scheduling algorithm)

建立数学模型分析了其性能;仿真实验证明

与原有的移动流媒体系统相比

使用2CMSS调度算法能够有效地节省网络传输开销

降低用户启动时延。

Abstract

A novel caching system architecture for mobile streaming was proposed

which was named 2CMSA（two-level cache mobile streaming architecture）.In this system

limitations for mobile streaming system such as small memory size in mobile terminal and low bandwidth in wireless access network were avoided.According to the 2CMSA

a scheduling algorithm of 2CMSS（two-level cache based mobile streaming scheduling） was designed;mathematical models were also achieved to analyze the performance of this scheduling algorithm.Simulation experiment proves that

comparing to the original mobile streaming system

by using the new two-level cache architecture and cache based scheduling algorithm

the network transmission cost and the client startup delay of the mobile streaming services can be decreased effectively.
