ABSTRACT:
An adaptive forward error correction (FEC) protocol for use in an asynchronous transfer mode (ATM) communication network is provided. Whether a feasibility condition is met indicating that FEC can compensate for an expected number of burst errors in a FEC encoded payload is determined. Subsequently, FEC encoding is performed on protocol data units (PDUs) within a payload to form the FEC encoded payload only when the feasibility condition is met. Adaptive FEC sending and receiving units which effectuate the adaptive FEC protocol are provided. In addition, an alternative adaptive FEC protocol is provided which determines a feasibility condition based on whether a PDU loss probability between connection service application points for a payload is greater than an effective PDU loss probability for the payload with associated FEC PDUs at a given load on the communication network. Also, a method for determining an overhead parameter for adaptive FEC in a communication network is provided.
