摘要
网络测试是及时了解网络运行状态、检测网络拥塞、提供接入控制参考依据以及保证网络服务质量的基础和必要手段。带宽测量属于网络的系统测试范畴,其相关测量算法一直是网络测试领域的研究热点和难题。文章在重点讨论可用带宽测量技术的基础上,对可用带宽测量工具Pathload进行了改进,实际测量结果表明改进算法在测量准确性等方面改善了测量效果。
Network measurement is the basis and necessary means for acquiring first-hand network state information, checking network congestion, supplying access control reference and guaranteeing QoS. Bandwidth measurement belongs to the category of network system test ＆ measurement, and its relevant algorithms have long been the focus and difficult problem. This paper, based on the discussion of bandwidth measurement technologies, describes the improvement of the measurement tool Path load. The actual measurement results indicate that the modified algorithm has improved the accurate measurement effectiveness.
