Bandwidth fragmentation, a serious issue in elastic optical networks (EONs), can be
suppressed by proper management in order to enhance the accommodated traffic demands …

It is known that by incorporating network function virtualization (NFV) in inter-datacenter
(inter-DC) networks, service providers can use their network resources more efficiently and …

This tutorial highlights challenges and opportunities in achieving efficient flexible optical
networks. Optical signal processing may potentially increase network flexibility because of …

The flex-grid technology or elastic optical network (EON) is accepted to be a propitious
solution for the future transport network due to its unique properties, which are bandwidth …

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

The rapid growth in communications and internet has changed our way of life, and our
requirement for communication bandwidth. Optical networks can enable us to meet the …

Flexible-grid elastic optical networks (EONs) have attracted intensive research interests for
the agile spectrum management in the optical layer. Meanwhile, due to the relatively small …

Hitless defragmentation has been introduced as an approach to limit the spectrum
fragmentation in elastic optical networks without traffic disruption. It facilitates the …

It is known that multicast provisioning is important for supporting cloud-based applications,
and as the traffics from these applications are increasing quickly, we may rely on optical …

We investigate dynamic pre-configured-cycle (p-cycle) protection design for spectrum-sliced
elastic optical networks (EONs). Several novel algorithms are proposed to use the spectrum …
