As the Inter-domain routing security problem becomes increasingly prominent, the detection of AS (Autonomous System)-level Internet evolution has become a research hotspot. This paper introduces AS Reach ability Distance (ASRD) and AS Connectivity Distance (ASCD) based on temporal distance, used to characterize the difference of AS reach ability and connectivity at different time respectively, and based on ASRD and ASCD, an algorithm of continuously detecting AS-level Internet anomalies is proposed. Experiments show that the proposed method can not only detect AS-level Internet anomalous event accurately, but also reveal the evolution laws of AS-level Internet in the long term.
