融合了多协议标记交换 (Multiprotocol L abel Switching,MPL S)和区分服务 (Differentiated Services,Diff Serv)技术 ,建立了 Diff Serv over MPL S模型 ,研究了在模型上承载区分服务 ,以实现端到端的服务质量(Quality of Service,Qo S)的技术 .详细描述了其中的重要概念、分组的转发处理过程及基于约束路由的标记分发协议 (Constraint- based Routing L abel Distribution Protocol,CR- L DP)的扩展细节 .
The Multi-protocol Label Switching (MPL S) and Differentiated Services (Diff Serv) technologies are integrated and the model of Diff Serv-to-MPL S is established. The model is designed to carry differentiated services to achieve end-to-end Quality of Service (QoS) technology described in detail its important concepts, packet forwarding process and Constraint-based Routing Label Distribution Protocol (CRLDP) Expand the details.
