Rigid fixed-grid wavelength division multiplexing (WDM) optical networks can no longer
keep up with the emerging bandwidth-hungry and highly dynamic services in an efficient …

In recent years, OFDM has been the focus of extensive research efforts in optical
transmission and networking, initially as a means to overcome physical impairments in …

Elastic optical networks (EONs) have been receiving extensive attention because of their
inherent flexibility and the efficiency with which they allocate fiber-bandwidth. For an EON …

In the past few years, many researchers have studied elastic optical networks, which exhibit
a dramatically improved transmission capacity compared with conventional optical networks …

In this paper, we present a quality-of-transmission (QoT) aware dynamic routing, modulation
level, and spectrum assignment scheme referred to as QoT-aware RSA. The proposed QoT …

In optical transport networks the quality of transmission (QoT) is estimated before
provisioning new connections or upgrading existing ones. Traditionally, a physical layer …

Elastic optical networks (EONs) enable network operators to have agile bandwidth
management in the optical layer. In this paper, we investigate dynamic and adaptive …

This paper presents an overview of future research activities in the field of optical
telecommunications. The year 2020 is considered a milestone, when the capacity of optical …

This paper proposes a data-driven bandwidth allocation (BA) framework for periodically and
dynamically reconfiguring an elastic optical network according to predictive BA (PBA) …

It is known that in multilayer interdatacenter optical networks (ML-IDCONs), network services
can generate numerous data-oriented tasks (DoTs) that require not only inter-datacenter …
