System for providing distributed group-based protection switching at a network element in a communication network. The communication network includes a plurality of interconnected network elements, and wherein the network element includes first and second card logic coupled to the communication network to transmit and receive network traffic. The system comprises selector logic distributed between the first and second card logic that includes first and second switching engines that have associated activity states that indicate how the network traffic is routed at the network element. The switching engines generate new activity states based on selected fault indicators. A processing system operates to detect fault conditions, generate the selected fault indicators, and receive the new activity states from the switching engines to perform one or more switch reconfigurations at the network element based on the new activity states, and thereby implement the distributed group-based protection switching.
