<p>A cell-based Forward Error Correction (FEC) scheme which is located in the ATM Adaptation Layer (AAL) is designed for the Service Specific Convergence Sublayer of the standardized AAL Type 5. The FEC scheme encodes cell-level protocol information, encodes frame-level protocol information into Protocol Data Units of the Common Part Convergence Sublayer of AAL5, and encodes and decodes the required redundant information by a Double Matrix Interleaving XOR scheme. Applications are networks where reliable high performance point-to-point and point-to-multipoint communication services are required, e.g. broadband integrated services digital networks, distributed multimedia systems, computer-supported cooperative work applications, and virtual shared memory systems.</p> |
