Abstract

Fasnet is an access scheme for high-speed local and metropolitan area networks based on a slotted unidirectional dual-bus structure. However, there are wasted slots between two consecutive cycles. These wasted slots reduce the line utilization of Fasnet. We introduce a modified protocol to reduce the number of such wasted slots by using a pseudo-end-station. We show that the line utilization is improved with the modified protocol.
