Metropolitan optical networks are undergoing significant transformations to continue being
able to provide services that meet the requirements of the applications of the future. The …

Consistent growth in the volume and dynamic behavior of traffic mandates new
requirements for fast and adaptive resource allocation in metro networks. We propose a …

Time-sensitive applications, most notably, for 5G fronthauling and Industry 4.0, require
deterministic (jitter-free) low-latency, highly reactive, and trustable networks, as opposed to …

A flexible all-optical format interconversion scheme based on a pump assisted nonlinear
optical loop mirror (NOLM) is proposed and numerically simulated for the first time to our …

The rapid development of emerging technologies has led to a significant increase in data
traffic, posing challenges for data centers in terms of storing, transmitting, and processing …

Today's network infrastructure evolves into two seemingly opposite directions: cloudification
centralizes functions that used to be distributed for economies of scale, at the expense of …

A pump-free and reconfigurable all-optical modulation format conversion (MFC) scheme for
multiple quadrature amplitude modulation (MQAM) signals by the designed parallel …

Forward error correction () is an essential technique required in almost all communication
systems to guarantee reliable data transmission close to the theoretical limits. In this chapter …

Flexible grid networks need rigorous resource planning to avoid network over-dimensioning
and resource over-provisioning. The network must provision the hardware and spectrum …

A key requirement in 5G networks is the demand of minimizing transport delay. In this paper
we propose and explore novel mechanisms for minimizing packet delay and delay variation …
