摘要：

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 allocation efficiency for scheduled demands. This approach, called Delayed Spectrum Allocation (DSA) promises network resources to each demand upon request for scheduling, but delays the selection and allocation of those specific resources until immediately before transmission begins. Through simulation, we are able to conclude that DSA improves resource consumption efficiency and lowers call blocking.(1)
