Assignment-based heuristic for SDM Networks with Multi-Core Fibers

Abstract

Due to the ever-increasing demand for the Internet, optical fiber networks are receiving a lot of attention. Elastic Optical Networks (EONs) have a potential future in next-generation high-speed networks due to their increased flexibility and better spectrum management. Moreover, Space-Division Multiplexing (SDM) is used to expand the fiber capacity further. One of the most difficult problems in elastic optical transport networks is the Routing and Spectrum Assignment (RSA). The goal of this study is to create and develop effective algorithm for internet traffic routing in SDM-based Elastic Optical Networks (EONs). The focus of this study is on a problem known as Routing, Spectrum, and Core Allocation (RSCA) for flex-grid SDM networks. Preliminary experimental results demonstrate good performance in terms of time and quality using an assignment-based heuristic.
