摘　　要：定义了不同的数据流转发模型,并利用网络仿真工具OPNET在所定义模型下分别对路由器的一些关键性能指标进行了测试,测试结果表明当转发模型为均匀流量时路由器的性能要远远好于非均匀流量转发模型下的性能。故得出IETF有关性能评测的方法与度纲不完备,未能对网络一般和极端环境下设备的性能进行评测,必须扩展IETF现有的性能评测度纲,从而为路由器的性能评价提供更全面的评价指标体系。Different types of the data streams switching models are defined, using OPNET which is the network simulating tools to test some performance metrics of routers. The simulation results show that the performance of routers is far better under the evenly switching pattern than it is under the unevenly switching pattern. It concluds that the IETF performance testing methods and metrics are imperfect because the network devices are not tested under the common and extreme situation. This leads to an expansion for existed IETF performance testing metrics. The work can provide the more performance evaluating metrics for routers.
