Pre-provisioning Protection in Elastic Optical Networks
Abstract
With the emergence of EON networks, protection techniques used for WDM networks are reevaluated and research of new techniques gains importance. This work aims to explore the main protection techniques and to compare offline, pre-provisioning, and online, provisioning, adapting the strategies taken from the literature to EON networks. This study explores the realistic view of predicting traffic and adapting routing techniques to this premise. This work presents a heuristic for routing and spectrum allocation for pre-provisioning of DLP, Dedicated Link Protection, and DPP, Dedicated Path Protection. Results show that the use of pre-provisioning techniques in EON obtains good results, compared to the classic provisioning solutions.
