Paper Abstract

A wavelength division multiplexed (WDM) broadcast star network is considered. The network has N tunable transmitters and receivers with nonnegligible tuning delay T. The network traffic is composed of continuous flows whose transmissions may be preempted and resumed. The traffic is delay constrained so that a bit cannot be delayed by more than a predefined number of time units denoted by D. Guaranteed nodal throughput results are presented for traffic patterns that are fair. In particular, if the nodal throughput is (lambda) then all nodes can transmit/receive at rate (lambda) as long as they do not transmit/receive more than this rate. When T very much less than D and NT very much greater than D, then the upper and lower bounds for (lambda) are approximately 4 D/NT and 1/4 D/NT, respectively. Notice that the conditions T very much less than D and NT very much greater than D mean that a single tuning delay is a small contribution to delay, but the aggregation of all the tuning delays may be a large contribution to delay.
