| 摘 要： | Multi-homing是存根网络（stub network）为增强网络连接的可靠性、提高网络性能而采取的一种技术手段.在考虑网络访问特性的前提下,针对主要的网络应用采用基于地址前缀的流量聚合方法,自网络流量中提取出测量地址集,并提出一种对不同ISP进行大范围网络性能测量的方法.通过建立性能与连通性评价量度,从测量结果中分析得到不同ISP在地址前缀和自治系统中的特征分布,该结果对于存根网络选择ISP和进行路由策略设定具有技术参考价值.

| Abstract: | Multi-homing has widely been employed by stub networks to enhance the reliability of their network connectivity and improve performance. On the premise of considering the characteristics of network access, we adopt traffic aggregation method to extract IPv4 address candidates of active measurement, and then present a methodology of network performance for large-scale measurements. Based on the mettics of performance and connectivity that we define, we analyze the characteristics of performance per prefix and per AS along different ISP access links. The measurement results are helpful for selecting alternative ISPs and configuring routing policy. |
