An efficient reservation system for local area networks based on CSMA/CD

Two channel reservation network (TCRN) is discussed. TCRN uses advance reservation and two channels to increase the channel throughput with lower delay than CSMA-CD. Two channels and FIFO form the TCRN. The contention channel carries the reservation broadcasts, the data channel delivers the actual data, and the reservation table keeps the priorities of message transmissions on the D-channel. TCRN operation, modeling, and simulation results are described, and TCRN is compared to other popular networks. TCRN is found to perform better than CSMA-CD, SRMA, and ring and polling networks with various numbers of stations.<
