Abstract
Feature Issue on Optical Interconnection Networks (OIN). We propose
access-restriction-based quality-of-service differentiation schemes, suitable for an
asynchronous optical packet switch with a contention resolution pool that contains
both tunable wavelength converters and fiber delay lines. The schemes aim at
obtaining a high degree of packet-loss-rate isolation, for a low increase in overall
packet loss rate, at the same time respecting the jitter tolerance of each class of
service. Numerical simulations quantify how the performance depends significantly on
the jitter tolerance of the traffic in general, and of the highest-priority class of
service in particular.
