Abstract

This paper proposes a new Medium Access Control(MAC) protocol named CONRAD for a passive-star basedsingle-hop WDM local lightwave network which efficientlysupports services with tight delay constraints, i.e. real-timetraffic, and best-effort services, .e. data traffic, directlyin the optical layer. The integration of both service typesin a packet-switched environment is primarily achieved bycombining two different reservation schemes on the controlchannel, instead of applying conventional priority strate-gies or circuit-switched approaches.Thereby, a significantimprovement of the access delay balance between real-timeand data transmission may be obtained, while the systemachieves high throughputs.
