Abstract

Cyclic-Reservation Multiple-Access (CRMA) is an access scheme for high speed local and metropolitan area networks based on slotted unidirectional dualbus structure. In CRMA, the headend generates the reserve commands periodically. Each node reserves a number of slots in each reserve command. Finally, the headend generates a sequence of cycles each of which is used to service the reservations on the corresponding reserve command. The length of each cycle is equal to the total number of slots reserved by the nodes in the corresponding reserve command. Generally, a longer cycle length will conduct a longer access delay and a lower slots utilization. In this paper, we propose a new reservation scheme to make the cycle length as short as possible. That is, some of used slots can be reused by the downstream nodes and hence the throughput is improved. Based on the simulation results, we found that our scheme obtains a greater improvement as the traffic locality is higher.
