纵向加密认证装置转发性能测试的研究

摘要

随着纵向加密认证装置在电力安全防护系统中的广泛部署,其转发性能对电力应用系统网络性能有着重要影响,对纵向加密认证装置的转发性能测试进行研究意义重大；设备的转发性能包括吞吐量及背靠背两项指标,在这两项指标传统单帧长测试方案的基础上,提出混合帧长吞吐量测试的方案,详细分析了测试范例及结果,并采用不确定度来评估测试结果的可信度；实验结果准确、有效地反映了纵向加密认证装置在理想及模拟真实的网络环境下处理数据包的能力,达到预期目标.%With longitudinal encryption and authentication devices widely deployed in power security system, the forwarding performance of such devices has crucial effect on scheduling performance of the whole power network system. Forwarding performance testing becomes an important part of test for such devices. The forwarding performance of a device includes two indices, throughput and back-to-back. On the basis of the traditional single frame size testing scheme of these indices, the mixed frame sizes scheme is applied to throughput test. Besides, test cases and their results are analyzed in detail and measurement uncertainty is utilized to evaluate the credible level of test results. The test results accurately and efficiently express the packet processing capability of longitudinal encryption and authentication devices in the ideal and simulation of real network environment, which achieves the desired goals.
