Abstract:
1. An apparatus for rerouting multiple traffics, comprising a path computation unit and a traffic path incorporation unit, wherein the path computation unit is configured: to forward, to the traffic path incorporation unit, a received uniform route computation notification message including information about a plurality of failed traffic connections; and to forward, to the traffic path incorporation unit, a route inquiry request sent by a head node of a failed traffic during a traffic failure inquiry period; the traffic path incorporation unit is configured: to receive the uniform route computation notification message forwarded by the path computation unit, to incorporate the plurality of failed traffic connections according to a traffic incorporation and route inquiry statistic algorithm, to obtain, from the path computation unit, updated routes with respect to the plurality of failed traffic connections as incorporated, and to store records of the updated routes; and based on the received route inquiry request forwarded by the path computation unit, to search the records to find a corresponding updated route, and to return, through the path computation unit, the found updated route to the head node requesting route restoration.
