中文摘要：

在网络建设和运行中,采用测试的方法对其性能进行评估对于网络的正常运营具有重要的意义.本文研究了网络路由收敛性能测试方法,为得到路由收敛性能指标,对OSPF和iBGP的路由收敛时间进行了测量.提出了一种简化的路由收敛时间测量方法,通过测量数据平面的传输性能指标,对路由控制平面的收敛时间进行估算.该方法对于测试设备要求不高,实施简单方便.采用该方法在CERNET2投入运营之前对其进行了路由性能测试,实验结果表明CERNET2在路由变化时具有较好的路由收敛性能.

英文摘要：

In network construction and running, it is very necessary to evaluate the network performance by the means of testing. This paper studies systematic testing methods of network routing convergence performance. Two routing convergence performance metrices OSPF and iBGP routing convergence time are measured. Simplified methods of routing convergence time measurement are presented. Via measuring transmission performance metrices of data-plane, convergence time of routing control-plane is estimated. The methods have no high requirements for test devices and are convenient to be applied. We use the methods to test the network routing convergence performance before CERNET2 is hunched. The experimental results show that CERNET2 has satisfying routing convergence performance.
