摘 要: | 文章讨论了基于区分服务(DiffServ)的IP网络中,路由器转发IP分组的三种模式(EF、AF、DE),讨论了边缘路由器对IP分组进行分类、测量、标记、整形和丢包的处理方法,分析了区分服务与服务水平协议(SLA)结合的重要性,给出了支持端到端实时业务传输QoS的基于区分服务的IP网络结构。

The QoS Technology of Transmitting Real-time Multimedia on IP Network Based on Differentiated Services |
| |
Abstract: | : The QoS technology of transmitting real-time media on IP network based on differentiated services is proposed in this paper.Three IP packet forwarding,include expedited forwarding (EF),assured forwarding (AF) and default behavior (DE),are discussed.The usage of classifier,meter,marker,shaper and dropper in the edge router are discussed.The importance of combining DiffServ and Service Level Agreement (SLA) is analyzed. |
