Abstract: With the ever-rising data volume that is demanded by the market,
network planning in order to minimize the necessary investment
while meeting the demands is constantly an important task for the network
providers. Synchronous Digital Hierarchy (SDH) and
Wavelength Division Multiplex (WDM) form the core of many current backbone
networks. In order to solve the provisioning and routing problem in such
WDM networks, we develop various metaheuristics
including GRASP,
variable neighborhood search (VNS) and the pilot method. An integer flow
formulation is modeled in AMPL and solved by CPLEX in order to obtain
optimal solutions as a reference for the heuristics. We present the
current results of an ongoing research project
