Minimizing delay and packet loss in single-hop lightwave WDM networks using TDM schedules

Considers single-hop WDM networks with stations equipped with tunable transmitters and fixed receivers. Access to the channels is controlled by a weighted TDM scheme. The authors study the problem of designing TDM frames to minimize the mean packet delay, as well as the mean packet loss probability given a finite buffer capacity. They develop optimization heuristics which, for non-uniform communication patterns common to parallel and distributed computations, represent a significant improvement over I-TDMA.
