多QoS机制的IP TV管理构架研究

Research on Management Architecture on IP TV Based on Multiple QoS Mechanism

为满足IP TV(基于IP网络的电视系统)对高接入带宽、高速率I/O(输入/输出)和QoS(服务质量)传输的要求,本构架综合带宽节约技术、业务量工程技术、接入控制技术、QoS传输技术等多种技术,能够根据用户业务应用的QoS需要统一调整这些机制.仿真实验显示,这些机制能在动态业务量环境中,给不同并发程度的用户业务应用提供较好的QoS保证.

In order to met the access bandwidth requirement,high I/O(input/output)speed requirement and QoS(quantity of service) transport requirement faced by IP TV(Internet protocol television),multiple QoS technologies such as bandwidth saving,traffic engineering,access control,QoS transport,are integrated in our architecture and adapted in a unanimous manner according to the QoS requirement of user application.Simulation result verifies that it can provide QoS to user service application in different parallel user number and dynamical traffic environment.
