Improving IP control plane (routing) robustness is critical to the creation of reliable and
stable IP services. Yet very few tools exist for effective IP route monitoring and management.
We describe the architecture, design and deployment of a monitoring system for OSPF, an IP
intradomain routing protocol in wide use. The architecture has three components, separating
the capture of raw LSAs (Link State Advertisements–OSPF updates), the real-time analysis
of the LSA stream for problem detection, and the off-line analysis of OSPF behavior. By …
