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.

Abstract: A method of placing prefix hijacking detection modules in a communications network includes selecting a set of candidate locations. For each candidate location, a detection coverage ratio with respect to a target Autonomous System is calculated. Based on the relative size of the coverage ratios, proposed locations for the prefix hijacking detection modules are determined.

Abstract: A device detects and diagnoses correlated anomalies of a network. The device includes an anomaly detection module receiving a first data stream including an event-series related to the network. The anomaly detection module executes at least one algorithm to detect a potential anomaly in the event-series. The device further includes a correlating module receiving a second data stream including other event-series related to the network. The correlating module determines whether the potential anomaly is false and determines whether the potential anomaly is a true anomaly.
