The present disclosure relates to a method to detect service degradation for certain priority classes traffic. Operations, Administration, and Management (OAM) is an integral part of networks. Connectivity Fault Management (CFM) and Bidirectional Forwarding Detection (BFD) is widely used in Layer 2 networks for OAM. Typically network administrators configure CFM/BFD sessions to monitor services passing through the network. Moreover, short interval CFM/BFD sessions are used to trigger protection switching based upon the fault observed in the data forwarding path. The present disclosure utilizes OAM sessions for per traffic class service degradation detection based upon an amalgamation of priority and sequence numbering. Specific priority class traffic degradation detection is based on BFD/CFM continuity check packets used for fault detection and non-sequenced service degradation detection.
