【摘要】 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．更多还原

【Abstract】 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.更多还原
