Dynamic Reconfiguration in Multihop WDM Networks

The advent of fast tunable optical transceivers makes it feasible to dynamically update the connectivity of multihop WDM networks to accommodate tra c demands that vary over time. Of major concern in such design is how the connectivity should react to changes in tra c patterns. We formulate the problem as a Markovian Decision Process, and we develop heuristics to obtain good recon guration policies and manage the state and decision space explosion.
