互联网从研究网络到商业网络的转化以及多种对 Qo S有不同要求的应用的出现要求互联网提供 Qo S.本文首先论证了在路由器中实现 Qo S的必要性 ,然后以此为基础 ,给出了在路由器中实现 Qo S模块所需要考虑的问题和实现框架 ,并详细讨论了实现细节 .最后在具有自主知识产权的 BQ 2 0 0 0路由器上对该模块作了测试 ,给出了评测 The advent of the Internet from research networks to commercial networks and from a variety of applications that have different requirements for Qo S requires that the Internet provide Qo S. This paper first demonstrates the necessity of implementing Qo S in routers and then based it on In the router to achieve Qo S module need to consider the issues and implementation framework, and discussed in detail the implementation details.Finally in the BQ200 with independent intellectual property rights of the router has been tested on the module, given the evaluation
