Optical multicasting has been considered resource efficient for multicast services. Light-tree
and light-trail are two technologies that support optical multicasting while the former requires …

In this paper, we investigate routing and spectrum allocation (RSA) approaches in elastic
optical networks for multicast traffic demands. We consider that a light-tree is constructed for …

Over a number of years the ever-increasing growth of traffic transferred over the internet has
become a common pattern. This particular trend was made even more discernible in 2020 …

Multicast provisioning is important for supporting applications such as data backup and
cloud computing in elastic optical data center networks (EODCNs). As the traffic demand …

The surge in demand for multimedia applications has brought a great pressure on network
bandwidth resources. In order to improve the efficiency of bandwidth resource usage and …

Multicasting, as a main transmission mode for most of the current applications in elastic
optical network, has attracted more and more research attention. In this paper, we …

In inter-datacenter elastic optical networks (IDC-EONs), many demands, such as data
backup, focus on being served before a specific moment rather than immediately. In …

This paper studies the load-balanced routing and admission control for point-to-multipoint
traffic flows in elastic optical networks (EONs). EONs have emerged as a promising …

Multicast transmission in elastic optical networks (EON) is a central problem. When EON
admits modulation schemes, the multicast problem is called multicast routing and …

This paper deals with the problem of multicast routing and the allocation of wavelengths in a
WDM network with optical splitters and converters. We present an exact formulation in …
