Abstract

We demonstrate how maximum entropy (MaxEnt) allocation strategies can optimally determine links within a flexgrid elastic optical network, thus requiring multiple fiber pairs to support 100% capacity growth with 34.3% improvement in the uniformity of spectrum allocations. We show how adding additional fiber to those links, which feature the highest number of demands in a link, allows optimum allocation of network capacity resources to all source–destination (S-D) demand pairs and maximizes the available spectral capacity to each demand. We also analyze the case of adding additional fiber to a link in order to reduce the number of contiguous demands present in the associated fiber, as an additional means to maximize the allowable channel capacity for each S-D demand.
