In this paper, we propose a set of ILP formulation with traffic grooming consideration for static multicast traffic in light-trail networks under the objective to minimize number of established light-trails. Our major idea is to reduce the multicast routing problem to several instances of unicast routing problems owing to the hop length limitation of(More)
In recent years, the concept of the elastic optical network (EON) was proposed and very quickly became an attractive solution for flexible channel bandwidth utilization. Analogous to the routing and wavelength assignment (RWA) problem in traditional wavelength-routed networks, routing and spectrum assignment (RSA) is the most basic and critical resource(More)
