INVESTIGATING LINK-STATE ADVERTISEMENT AGING IN OSPF FOR NETWORK FAULT DIAGNOSIS

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Open Shortest Path First (OSPF) utilizes Link-State Advertisements (LSAs) to keep precise information about network topology. This research empirically examines the aging behavior of LSAs and their significance in diagnosing faults within OSPF networks. In a simulated OSPF environment, different fault scenarios including link failures, adjacency instability, and inconsistencies within the database are introduced and assessed based on LSA age variations among various LSA types. The findings indicate that unusual aging patterns are effective indicators of hidden network problems. The study verifies that tracking LSA aging metrics improves fault detection accuracy and enhances troubleshooting effectiveness in networks using OSPF.
