摘　　要：通过配置区分服务体系实现基于光GMPLS环状网络的QoS测量,涉及到不同的实时多媒体服务。讨论并分析区分服务结构的三种服务级别的特性。仿真结果表明,在网络过载的情况下,快速转发类和保证转发类都有很好的保护作用。加速转发类适合于实时服务,而最大努力类对任何类型的服务性能都非常低,同时保证转发非常适合于视频流。Results on QoS measurements related to different real time multimedia services in an optical network based on a ring configuration obtained, and configured with differentiated service （DiffServ）over multi-protocol label switching architecture. The characteristics of DiffServ architecture there are three different classes of services are also discussed and analyzed. The final simulated result indicates that the expedited forwarding class and the assured forwarding classes are also well protected under conditions of network overload. In particular, expedited forwarding is appropriate for real-time services; the best effort class has very low performance for any type of service, while assured forwarding is well suitable for video streaming.
