Prioritized Detection of BFD/S-BFD Faults for Fault Recovery and Datapath Availability

Abstract

Systems and methods provide prioritizing detection of Bidirectional Forwarding Detection (BFD) or Seamless BFD (S-BFD) faults in a network having BFD or S-BFD sessions. In an embodiment, a method includes steps of specifying a prioritization attribute for at least one BFD or S-BFD session of the BFD or S-BFD sessions to designate the at least one BFD or S-BFD session as high priority relative to other concurrently configured sessions of the BFD or S-BFD sessions; monitoring the BFD or S-BFD sessions for faults; and upon detecting a fault in the at least one BFD or S-BFD session, processing the detected fault with higher precedence than faults detected in sessions not designated as high priority, thereby expediting recovery for critical traffic flows and reducing downtime.
