摘　　要：为了使IP网能满足音频、视频等实时业务的要求,研究在IP网上对不同业务提供相应的服务质量(QoS)保障是很重要的。文中重点对资源预留协议(RSVP)、综合服务(IntServ)以及区分服务(DiffServ)等几种QoS方案进行分析和讨论,并提出两个合成方案,即IntServ与DiffServ结合以及IP融入ATM的模型,可以解决网络中的延迟问题,实现网络资源的共享,并阐述了如何在电力通信网中利用MPLS技术传送关键业务。In order to make the IP networks meet the requirement of some real-time services such as audio and video,it is necessary to research on QoS for different services of IP networks. Several QoS protocols are analyzed and discussed in this paper,including Resource Reservation Protocol(RSVP),Intserv,Diffserv and MPLS. There are two methods that are beneficial to reduce the delay time in Internet and realize the share of Internet resources. One method is combining Intserv/RSVP with Diffserv,and the other is the model of IP over ATM. In the end,this paper expounds how to utilize MPLS in electric power communication networks according to the demands of key operations.
