研究了基于ATM的MPLS,重点研究和分析了具体实现MPLS流量工程的ATM流控措施、使用约束路由的标记分发协议、路由协议,为MPLS流量工程的具体实施提供了参考。同时研究了MPLS多协议标记交换技术融合IP路由技术、ATM的QoS(Quality of Service)及交换技术,使得流量工程模式可以部署在基于IP的网络,其中包括ATM网上承载IP业务的模式。
The MPLS based on ATM is researched, and the ATM flow control measures for implementing MPLS traffic engineering are researched and analyzed emphatically. The label distribution protocol and routing protocol using constrained routing are provided for reference for the concrete implementation of MPLS traffic engineering. At the same time, MPLS multi-protocol label switching technology is integrated with IP routing technology, ATM’s QoS (Quality of Service) and switching technology so that the traffic engineering mode can be deployed on IP-based networks, including the mode of carrying IP services on the ATM network.
