用于VoD的协作代理服务器体系结构以实现高QoS并减少传输时间和成本
Cooperative Proxy Servers Architecture for VoD to Achieve High QoS with Reduced Transmission Time and Cost
摘要：
- 本文的目的是提出一种新的语音点播（VoD）架构和实现一个有效的负载分担算法，以实现服务质量（QoS）。该方案通过在本地代理服务器组[LPSG]的代理服务器之间以及在以环形方式互连的相邻LPSG之间共享视频来降低从集中式多媒体服务器（CMS）到代理服务器（PS）的传输成本。这导致非常低的请求拒绝率、传输时间和成本的减少、CMS上的负载的减少以及用户的高QoS。仿真结果表明，初始启动延迟可接受，减少了传输成本和时间，负载分担之间的代理服务器，LPSG之间和CMS和PS之间。
英文摘要：
- The aim of this paper is to propose a novel Voice On Demand (VoD) architecture and implementation of an efficient load sharing algorithm to achieve Quality of Service (QoS). This scheme reduces the transmission cost from the Centralized Multimedia Sever (CMS) to Proxy Servers (PS) by sharing the videos among the proxy servers of the Local Proxy Servers Group [LPSG] and among the neighboring LPSGs, which are interconnected in a ring fashion. This results in very low request rejection ratio, reduction in transmission time and cost, reduction of load on the CMS and high QoS for the users. Simulation results indicate acceptable initial startup latency, reduced transmission cost and time, load sharing among the proxy servers, among the LPSGs and between the CMS and the PS.
