Fixed Size and Variable Size Packet Models in an Optical Ring Network: Complexity and Simulations
Résumé
In this paper, we compare the use of two packet models in slotted optical ring networks: a model where each packet has to be routed in consecutive slots, and a model where the slots that form a packet can be routed independently. We first focus on the algorithmic complexity of the related problems. Then, we give the results we obtain with an OMNET simulator in terms of packets overdelay and jitter.
