Lightpath Topology Configuration for Wavelength-Routed IP/MPLS Networks for Time-Dependent Traffic

Overview The integration of lightpath topology design and IP/MPLS traffic engineering provides greater flexibility for next generation networks. This paper considers the integrated design problem of configuration of lightpath topology and optimal routing of IP/MPLS tunnels on this lightpath topology for time-varying traffic. A mixed integer linear programming model is proposed to design an optimal configuration of lightpath topology, which takes time-dependent traffic demand as an input to the model for IP/MPLS traffic engineering. Two variants of the problem are considered: in the first variant, re-routing of IP/MPLS tunnels is not allowed from one-time period to another while reconfiguration rerouting is allowed in the second variation.
