基于MPLS的网络服务质量分析

Analysis of Quality of Service(QoS) in Network Based on MPLS

本文针对软交换网络服务质量中的分组丢失问题,研究了控制和业务相分离的软交换网络的体系结构,讨论了电信网络的演进趋势。论文从IP技术的角度,分析了分组丢失的原因以及以分组为对象和以网络为对象的解决方案,重点讨论了多协议标签技术对服务质量的保证措施,利用该技术解决服务质量可以保证网络良好的可靠性和安全性,系统开销也会很小。

Aiming at solving the problem of packet loss in QOS of softswitching network, the system structure of softswitching network with seperated control and service is studied in this paper. The evolution trends of telecommunication network are discussed. From the viewpoint of IP technology, the reason of packet loss and the solutions with packet as object and 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 better reliability and security of network and bring less overhead to system.
