Abstract
Techniques for supporting fault tolerance in communications systems are described. Fault notification messages are communicated which may be affected by a detected/reported service disruption. End nodes receiving a fault notification message determine if the message indicates a disruption in a node that is critical to the end node receiving the message. If the indicated disruption is in a critical node, the end node takes action to ameliorate the effect of the reported condition. Fault notification messages indicating disruptions in nodes which are not critical to the end node receiving the fault notification message may be ignored once it is determined that the indicated disruption is in a node which is not critical to the end node receiving the message. The invention described herein minimizes service disruption following fault, failure or outage of critical network nodes, improving overall system robustness and resiliency.
