Proposal for an SDN‐Like Innovative Metro‐Access Optical Network Architecture
International Journal of Optics, Volume 2019, Issue 1, 2019., 2019 Today, telecommunication operators are facing an epochal challenge due to the need of higher reconfigurability, flexibility, and dynamicity for their networks. In the latest years, this necessity has been addressed by the introduction of Software‐Defined Networking (SDN), mainly in the fields of data centers and core networks.

A New Prime Code for Synchronous Optical Code Division Multiple‐Access Networks
Journal of Computer Networks and Communications, Volume 2018, Issue 1, 2018., 2018 A new spreading code based on a prime code for synchronous optical code‐division multiple‐access networks that can be used in monitoring applications has been proposed. The new code is referred to as “extended grouped new modified prime code.” This new code has the ability to support more terminal devices than other prime codes. In addition, it patches
