| 摘 要： | IP／WDM是目前网络发展的新动向。WDM技术增大了网络传输容量，为IP业务提供更加方便快捷的服务，但IP业务中的语音、视频、实时多媒体应用却对网络的服务质量QoS提出了更高的要求。介绍了IETF提出的几个QoS服务模型和机制，即集成服务(IntServ)／RSVP模型、区分服务(DiffServ)模型、多协议标签交换(MPLS)以及它们在IP／WDM网中的应用。

| Abstract: | IP/WDM is a new development direction of networks,for it expands the capacity of net transport and gives more con-venient services to IP affairs.But the voice,video and real-time multimedia applications should need more QoS support.Someservice models and mechanisms and the applications to IP/WDM were addressed,such as IntServ,DiffSery and MPLS,whichwere proposed by IETF to meet the demand for QoS. |
