Latency-Crosstalk-Aware Resource Allocation Based on Multi-granular Node Deployment in SDM-EONs

In SDM-EONs, we first present a multi-granular node deployment scheme, and then implement a latencycrosstalk-aware resource allocation algorithm based on the multi-granular node to reduce transmission latency and crosstalk.

I. Introduction

The combination of space division multiplexing (SDM) technology and elastic optical networks (EONs) has gained significant attention due to its potential for increasing the capacity of optical transmission systems [1–2]. In the realm of SDM optical networking, the development of multi-core fibers (MCFs) that contain several single-mode cores in the same fiber has emerged as the most extensively researched and promising advancement [3].
