【摘要】 研究了在综合服务/区分服务这种混和网络模型中，如何提供具有确定端到端延时要求的服务。研究了综合服务域的端到端延时，定义了区分服务域的确保延时服务。在此基础上给出了混和网络模型的延时保证QoS路由算法，并对这种延时服务在网络中的包丢失进行了讨论。更多还原

【Abstract】 This paper is for the mixed network model of IntServ/DiffServ, supplying service of the end-to-end delay confirmation. It studies the end-to-end delay of the IntServ field, defines the service for delay confirmation of DiffServ. On the basic, it also offers the delay confirmation QoS routing algorithm for this mixed network model . Finally, it discusses the packet-loss for this service on the mixed network.更多还原
