Abstract

   This documentary provides a routing, spectrum and core assignment
   method with the dividing frequency slots area for space division
   multiplexing elastic optical networks. This effective RSCA method to
   solve this problem better. The proposed method utilizes the Frequency
   Slots Area (FSA) concept and first-last fit policy of frequency slots
   assignment to have less spectrum fragments, lower crosstalk, smaller
   traffic blocking probability and higher spectrum resource utilization.

1. Introduction

   With the rapid development of Internet technology and the emergence
   of new applications such as intense social networking, real-time
   gaming, High Definition audio-video streaming and cloud computing,
   the demand for network capacity has increased greatly. The capacity
   of traditional single-mode fiber is close to its physical capacity
   limit, so the SDM technology that can greatly improve the network
   capacity has received more and more attention. In SDM technology, MCF
   is one of the most promising technology. On the other hand, for the
   sake of flexible and effective use of spectrum resources, EON has
