Flexgrid technology is now considered to be a promising solution for future high-speed
network design. In this context, we need a tutorial that covers the key aspects of elastic …

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 …

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 …

In this paper, we study the multicast-capable routing, modulation, and spectrum assignment
(MC-RMSA) schemes that consider the physical impairments from both the transmission and …

Recently, to cope with the ever-growing traffic volumes and network services in the Internet,
the coherent point-to-multipoint transceivers (P2MP-TRXs) enabled by digital subcarrier …

Compared to legacy wavelength division multiplexing networks, elastic optical networks
(EONs) have added flexibility to network deployment and management. EONs can include …

Elastic optical networks (EONs) can make service accommodation more flexible and precise
by employing efficient routing and spectrum allocation (RSA) algorithms. In order to improve …

With the fast deployment of datacenters (DCs), bandwidth-intensive multicast services are
becoming more and more popular in metro and wide-area networks, to support dynamic …

Nowadays, the booming of emerging network services have shifted the major traffic pattern
in metro-aggregation networks from point-to-point (P2P) to hub-and-spoke (H&S). Hence, it …

We propose and investigate a subtree scheme for all-optical multicast routing, modulation
level and spectrum allocation (AOM-RMSA) in elastic optical networks. A multicast request is …
