Abstract
We propose a distributed medium-access control (MAC) protocol for an
asynchronous, optical-packet-switch architecture, suitable for an efficient,
scalable, and flexible interconnected ring network. We compare the complexity of our
proposal with that of existing techniques to support variable-length packets and
with node architectures that enable spatial wavelength reuse. Simulations quantify
the throughput increase enabled by the MAC protocol and show that moderate hardware
resources are sufficient to offer low-packet-loss rates with low maximum delay and
delay jitter. Finally, we show that the network efficiently supports bursty
traffic.
