We investigate the problem of dynamically routing and spectrum assignment for advance reservation anycast requests using a novel algorithm called Delayed Spectrum Allocation (DSA). We evaluate the flexible window STSD (Demands that specify start-time and duration) to further improve request blocking. Through extensive simulation results we show that anycast with flexible STSD using DSA approach can...
In response to bandwidth-hungry applications, the field of Elastic Optical Networks (EON) has emerged. In this paper we investigate the provisioning and allocation problem in EONs, which presents a number of new and exciting challenges not otherwise present in optical networking solutions. We propose a novel technique for solving the Routing and Spectrum Allocation (RSA) problem which improves resource...
