Paper Abstract

This paper presents R-Daisy, a scalable all-optical packet network where each node is equipped with one wavelength-tunable transmitter and one fixed-wavelength receiver. Network scalability is obtained with a novel multifiber ring topology that allows for wavelength spatial reuse and requires an optical transmitted power proportional typically to the square root of the number of nodes. The topology of R-Daisy provides one logical channel per destination node. Each channel is shared in statistical time division by all nodes transmitting to a given destination. A channel inspection capability allows the implementation of slotted ordered access protocols. Three collision-free multichannel access protocols are proposed in the paper, and their performance comparison is carried out through simulation.
