Large-scale IP network BGP routing entry detection method and device

Номер: CN104348672A
Принадлежит:

The invention discloses a large-scale IP network BGP routing entry detection method and device, and relates to the field of an IP network and a BGP routing technology. The method comprises the steps that a historical statistical average value N of the number of routing entries broadcasted to an internet by an AS is acquired; the number of routing entries broadcasted by the AS in an internet BGP routing table at the time of t in a predetermined period is acquired; the class variance of the number of routing entries of the AS in the predetermined period is calculated; and degree of deviation of the number of routing entries broadcasted by the AS in the predetermined period is confirmed according to the class variance. According to the method and the device, the fluctuation situation of the number of BGP routing entries broadcasted to the internet by all the AS is quantified via the class variance; the "class variance" criterion is high in real-time performance, simple in calculation and visual ...
