Distributed Inter-AS route monitor-Distributed Internet Route Eye (DIRE)

Distributed Internet Route Eye (DIRE) is a distributed agent architecture for inter-autonomous system (AS) route monitoring. In this architecture, monitor agents (MAs) record detailed BGP route updates from border gateway protocol (BGP) routers, and operator agents (OAs) query multiple MAs for specific information and infer the source and cause of the problems. Currently, MA implementation is near completion and actual route transitions can be monitored. The potential for flap source inference by OAs is examined using actual route transition data monitored by MAs. This system is capable of providing faster, easier access to more detailed information for coping with routing instabilities
