The implementation of BGP-Update based monitoring method for routing anomalies

In this paper, BGP-Update based monitoring method is proposed to effectively alleviate bandwidth tension and link congestion, and eventually resolve the problem of update message flooding when routing anomalies. Such monitoring method tracks routings and dynamically displays the alternations of selected routings and its updating quantities by analyzing collected BGP-Update messages. With the help of Internet routing structure in IP level from AS diagram we will successfully locate routing anomalies quickly. Moreover, in the paper we establish a new framework for routing message filtering — classifying update messages to reduce bandwidth waste and storage space waste when excluding causes of routing anomalies one by one, which demonstrates the superiority and great applicable prospects.
