Rating Autonomous Systems

Rating autonomous systems helps in establishing and maintaining mission critical Internet communication paths. We elaborate performance metrics, tools, and quality indicators to rate autonomous systems. An initial rating approach based on traceroute measurements led to the discovery of the frequent effect of non-increasing round-trip times in traceroute measurements. Our improved outlier-based rating approach addresses this issue and allows the real-time detection of autonomous systems causing poor internet connection performance as well as the comparison of autonomous systems against each other over an extended period of time.
