Cut-through bridging for CSMA/CD local area networks

A novel bridging architecture, called a cut-through bridge, which can be used to interconnect existing carrier-sense multiple access with collision detection (CSMA/CD) LANs is proposed. This bridge uses the cut-through switching concept. After providing a design of this bridge, the authors examine its performance via a detailed simulation model. They demonstrate the performance enhancement achievable by the cut-through bridge over a normal bridge, namely lower average frame delay while attaining the same maximum throughput as the latter. Since the cut-through bridge can be readily used to replace passive repeaters while achieving superior performance, it has promise for immediate application in existing CSMA/CD LANs
