摘　　要：该文介绍了IETF下一代信令工作组NSIS(Next Step In Signaling)的QoS信令协议框架,分析了区分服务网络QoS信令模型-RMD(Resource Managementin DiffServ)及其聚集预留状态管理算法。仿真实验证明,在负载较重的情况下,受网络时延抖动和信令分组丢失的影响,RMD难以保证聚集流的服务质量,并指出需要采用适当的分组调度策略以解决该问题。This paper first introduces the QoS Signaling Protocol framework of the IETF working group on Next Steps In Signaling （NSIS）, then RMD （Resource Management in DiffServ）, the QoS signaling model of the DiffServ network, and its algorithms for managing aggregated reservation state are introduced and analyzed. In the case of heavy load, the simulation result demonstrates that RMD cannot guarantee the QoS of the aggregated traffic due to the network jitter and the lost of signaling messages, and that proper packets scheduling policy must be adopted to solve this problem.
