This work demonstrates the use of spatial division multiplexing (SDM) to implement spine-
leaf datacenter network topologies. We consider two possible scenarios, with the first …

Abstract Virtual Network Functions (VNFs) are implemented as software instances on
generic servers in Data Centers (DCs). A network service is implemented by an ordered list …

Virtual optical network embedding (VONE) involves two processes, node mapping, and link
mapping. Node mapping decides which data center to place the virtual nodes (VNs). Link …

The problem of finding a lightpath to provision a connection request in space-division
multiplexing elastic optical networks (SDM-EONs) involves routing, modulation, spectrum …

This paper quantifies the potential reduction in the number of required transceivers that the
use of probabilistic constellation shaping (PCS) can bring to Flex-Grid over multicore fiber …

This chapter overviews the various existing solutions for optimizing the Space Division
Multiplexed‐Elastic Optical Networks (SDM‐EONs). Firstly, in view of enabling the …

Probabilistic constellation shaping (PCS) has emerged as an advanced modulation
technique that provides a fine-grained software-defined trade-off between achievable …

In this paper, the modulations are classified by six types of deep learning (DL) methods in
Elastic Optical Network (EON). In EON, flexible coherent transceivers are applied that can …

With the development of communication technology and the increasing popularity of network
services, multiple opportunities along with challenges have been brought to network …
