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 …

Energy consumption efficiency during resource allocation is crucial for large scale networks.
The evolution of space division multiplexing elastic optical networks (SDM-EONs) has …

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

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 …

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 …

Due to the flexibility and adaptivity of elastic optical networks (EONs), IP-over-EON would be
a promising infrastructure for next-generation backbone networks. As a backbone network …

In elastic optical networks, two lightpaths sharing common fiber links might have to be
isolated in the spectrum domain with a proper guard-band to prevent crosstalk and/or …

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 …

Recently, with the development of IP and elastic optical networks (EONs), the network
control and management (NC&M) scheme for IP-over-EONs, which can facilitate effective …
