IP QoS解决方案

IP QoS Solution

IPQoS技术的发展经历了从无QoS保障的“尽力而为”的网络服务,基于资源预留协议的IntServ解决方案,基于差分服务代码点(DSCP)的DiffServ解决方案,MPLSTE技术,到MPLSDiffServ-AwareTE解决方案的历程。其中,IPDiffServ,MPLSDiffServE-LSP以及MPLSDiffServ-AwareTE将成为主流的QoS技术。本文还介绍了华为公司IPQoS解决方案的组网应用:VoIP的QoS解决方案、多网合一的QoS解决方案和城域网多媒体业务的QoS解决方案。

IP QoS technology develops from non-QoS-guarantee best-effort network service,RSVP-based IntServ solution,DSCP -based Diff Serv so lution,MPLS TE technology,to MPLS Diff-Serv-Aware TE solution.Among these,IP Diff-Serv,MPLS DiffServ E-LSP and MPLS Diff-Serv -Aware TE will become mainstream QoS technology.Networking application of IP QoS so lution of Huawei Co.is also introduced in this paper,which in cludes VoIP QoS solution,net-work in te gra tion QoS so lu tion and MAN multi-media service QoS solu tion.
