摘　　要：在Internet迅速发展的今天,人们非常关注如何能够高效、高质量地传输Internet业务以及实时多媒体业务。传统Internet是一种尽力而为的服务方式,它越来越不能适应一些新业务(如IP电话、视频会议、电子商务等)的服务质量(Quality of Service)要求。因此,IPQoS越来越引起人们的关注。本文介绍了网络如何对服务质量进行一系列的支持。还分析了几个支持QOS的网络模型,像综合服务模型(IntServ)、区分服务模型(DiffServ)和多协议标签交换(MPLS)。With the current boon in Internet usage especially due to its proliferation into business, there is a greater and more urgent need for the transmission of efficient and high-quality service and real-time multi-media service. 1P is currently a best-efforts service, now it can not fits for the service in IP networks. Quality of Service has been a research issue in sodety. This is a paper about IP QoS.It introduces how the IP networks vary to support QoS. It also provides some net models about IP QoS. Such as Integrated Services （IntServ）, Differentiated Services（DiffServ）, Multiprotocol Label Switching（MPLS）.
