Abstract: Routers are the critical devices in the network environment. However, descriptions of the existing standards and specifications （e.g. Request For Comment, RFC） for performance test of routers are too simple to be used in practice. For instance, the related RFC specification provides a static test framework of routers in an ideal environment, the results of which cannot stand for the real performance of routers. Therefore, it designs a new environment for dynamic test, in which the packet lengths and packet intervals are variable to simulate stream parameters in actual network environment. The results of the performance test become more closer to the one in actual network environment. Finally, based on the major requirements of performance test, it presents a comprehensive evaluation method based on principal component analysis, which provides a new idea and reference for the choice of routers and the evaluation of their performance.
