Abstract
A communication network is operated by identifying at least one potential hijack autonomous system (AS) that can be used to generate a corrupt routing path from a source AS to a destination AS. For each of the at least one potential hijack AS the following operations are performed: identifying at least one regional AS that is configured to adopt the corrupt routing path from the source AS to the destination AS and determining a reflector AS set such that, for each reflector AS in the set, a source AS to reflector AS routing path and a reflector AS to destination AS routing path do not comprise any of the at least one regional AS. A reflector AS is then identified that is common among the at least one reflector AS set responsive to performing the identifying and determining operations for each, of the at least one potential hijack AS.
