设计并实现了一种基于RFC2544协议的网络设备测试仪,首先讨论了网络互联设备测试标准RFC2544协议的4种测试标准(吞吐量、延迟、丢失率、背靠背)以及硬件开发平台Tile64卡块的结构和工作原理,然后论述了网络设备设备测试仪的设计架构,以及在Tile64芯片上进行系统方案的实现过程。实验测试结果表明,该设备可以高效的完成网络设备测试功能,且性能上可以进一步提升。
A network equipment tester based on RFC2544 protocol is designed and implemented. First, four test standards (throughput, delay, loss rate, back-to-back) of RFC2544 protocol are discussed, and the structure of the hardware development platform Tile64 And working principle, and then discusses the design of network equipment and equipment tester structure, as well as in the Tile64 chip on the realization of the system program. Experimental results show that the device can efficiently test the network equipment and can be further improved in performance.
