一种基于被动测量的网络性能评估方法

摘要

网络性能分析是衡量网络服务质量和用户体验质量的关键方法和手段.如何有效地评估网络性能,也是各大网络运营商最关心的问题之一.论文引入了网络健康度这一概念,采用基于被动测量的网络性能评估方法,针对中国科技网骨干链路上的真实流量,从RTT、平均吞吐率、正常连接率等方面整体评估了中国科技网的网络性能.%The analysis of network performance is critical methods and means to measure the network quality of service and the quality of the user experience. It is the greatest concern of the major network operators, how to assess network performance effectively. In this paper, the network performance assessment method is employed based on passive measurement to get real traffic on the backbone link of the China Science and Technology Network, the introduction of the concept of network health through RTT, throughput and the normal connection rate assessing the network performance.
