| 摘 要： | 针对目前在实际的IP网络中部署QoS面临的技术和政策等各方面的困难,本文在DiffServ的服务框架下,提出了一种分层的QoS实现机制,即将全网的QoS控制分为域间的QoS控制和域内的QoS控制.域内的QoS以Internet上的自治系统为一个相对独立的QoS"域"(如某个ISP、政府或学校的网络)来实现QoS控制,以满足QoS的增量部署要求,以及保持QoS机制的可扩展性(适应网络规模的变化)和技术进化要求.本文着重考虑了在域内实现基于带宽代理的QoS体系结构,这种体系结构综合考虑了QoS路由、接纳控制、网络政策管理等因素,因此能实现良好的QoS保证并在网络域内部实现整体优化.

| Abstract: | To resolve the technology and policy difficulties of the deployment of QoS control among current IP networks, this paper presented a hierarchical QoS control mechanism according to the DiffServ framework, i.e. divided the whole network's QoS control into inter-domain QoS control and intra- domain QoS control. In this paper, the BB-based intra-domain QoS control was given a special attention. In the BB-based QoS control architecture, the QoS routing, admission control, and network policy management were taken into account for a whole, thus, the network optimization can be easily realized. |
