Abstract

Concurrent token ring (CTR), a multiple-access protocol for ring-type area networks, is proposed. In CTR, message frames are partially removed by the destination node. A truncated portion of the frame, which contains the source and destination addresses, is configured by the destination into a conditional token which is allowed to circulate back to the source for removal. The conditional token informs ´downstream´ nodes of busy data paths and allows them to establish concurrent message transmission if resources are free. Simulation results indicate that the CTR protocol has a higher throughput and shorter transmission delay than the IEEE 802.5 token ring.<>
