Abstract
This article presents a mathematical model that results
in a low-cost network design to satisfy a set of point-to-point
demands that arrive and leave the network along of time. It considers
the problem of routing working traffic and assigning wavelengths in
an all-optical network avoiding if possible that wavelengths
assignment changes and flow rerouting. The model allows to know when
a reconfiguration/expansion is needed. The model provides a physical
network configuration selecting a lowest cost set of components of
the network (subnetworks and OXCs) with sufficient capacities to
attend the demands and the required wavelengths in all time.
