Overview:

Efficient planning of optical networks requires an allocation of network capacity subject to certain economic or capacity constraints so that a forecasted network (lightpath) demand matrix or other performance objectives can be satisfied. Much research on optical networks has concentrated on static design, which aims to either minimize the maximal number of wavelengths in each fibre as in, or to minimize the maximal network congestion level as in, etc. However, when serving dynamic lightpath demands, a design simply based on a static forecasted demand matrix cannot perform well. New approaches that take into account the lightpath demand dynamicity and uncertainty need to be developed.
