透子网网络吞吐量测试设计

网络数据包吞吐量测试是评价网络性能的重要指标，对于不同帧长的以太网数据包，由于开销所占数据包比重不同，网络处理能力差异较大. 在FPGA中，采用硬件的方式产生线速网络吞吐量测试帧，远端从机环回测试帧，回传测试结果，可以分别测试网络的上下行网络吞吐量，准确评价网络链路的吞吐量. 结果表明，使用透子网的网络吞吐量测试方法可以很好地用于不同网络节点间的吞吐量测试，是一种实用、有效的测试手段.

Testing Design for Cross Subnet in Network Throughput

The network throughput is an important specification to evaluate the network performance, and the ability of network processing is difference due to the proportion of overhead in packets. The test network was designed based on FPGA, which rate can reach line speed. The work status of slave machine is controlled by host, which sends back the test results. The uplink and downlink throughput can be tested by this way, further, the network performance is evaluated. It shows that method with cross subnet test throughput of the network can be used for different nodes of the network.
