MPLS网络的QoS探索

Explored on QoS in Network Based on MPLS

笔者主要解决软交换网络中QoS的分组丢失问题,讨论了控制与数据相分离的软交换网络的体系架构,以及电信网络的发展趋势.分析了IP网络分组丢失的原因,进而提出以分组为对象和以网络为对象的解决方案,着重讨论多协议标签技术对服务质量的改进.由此得出,应用该技术解决服务质量,可以用较小的系统开销保证电信网络的可靠性和安全性.

Aiming at solving the problem of packet loss in QoS of soft switching network, the system structure of soft switching network with separated control and service is studied in this paper. The evolution trends of telecommunication network are discussed. The reason of packet loss and the solutions with packet as object and with network as object are analyzed. Furthermore, the assurance measure of MPLS for QoS is discussed in emphasis. Solving QoS by making use of MPLS can guarantee the better reliability and security of the network.
