Abstract

DBORN (Dual Bus Optical Ring Network) is a new network architecture for wavelength division multiplexing metropolitan area networks. In DBORN, metro clients like enterprise networks are connected to the optical metro-ring by edge nodes which share the wavelength channels on the ring. In order to allow for a high-speed optical interface on the upstream wavelengths while avoiding active optical switching components, a carrier sense multiple access/collision avoidance (CSMA/CA) medium acces control (MAC) protocol is realized. In this paper, the MAC protocol and the closely related transmitter interface are described first. Then, the performance of the MAC protocol is evaluated whith respect to important system parameters like slotted/unslotted working mode, burst size distribution and node position in terms of the mean waiting time as well as the node- to-hub delay. Finally, buffer dimensioning for the transmitter and the performance impact of a bottleneck interconnection link in the local edge node are analyzed.
