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

5G network slicing allows partitioning of network resources to meet stringent end-to-end
service requirements across multiple network segments, from access to transport. These …

As the services in elastic optical networks (EONs) are bandwidth-intensive, unpredictable
and dynamic, increasing network factors are emerging to affect the performance of network …

In this paper, we formulate an integer linear programming (ILP) to perform multicast routing
and spectrum assignment (MRSA) in elastic optical networks, which serves jointly a set of …

The elastic optical network is one of the emerging technologies in the optical network
paradigm, and it has been highlighted by many researchers in the past few years. So far, a …

The spectrum efficiency is a greatly important issue when we establish connection requests
in elastic optical data center networks (EODCNs). In this article, we address the spectrum …

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 …

Network virtualization has been proposed as a promising method to mitigate the ossification
of the Internet by allowing multiple heterogeneous virtual networks (VNs) to coexist on a …

This paper proposes a survivable virtual network embedding model over elastic optical
networks considering shared protection against any single substrate node or link failure. A …

The sub-tree-based optical multicasting scheme provides a spectrum-efficient approach to
providing emerging multicast services in optical data center networks. Moreover, multicast …
