We consider an elastic all-optical network, where each node is multicast-capable and does
not support spectrum conversion. In such a network, for a given set of static multicast …

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 …

In this paper, we focus on the survivability of elastic optical networks (EONs) that jointly
support two types of traffic demands: unicast and anycast. To provide network survivability …

Abstract Elastic Optical Networks (EONs) support the flexible allocation of bandwidth and
contribute to high-speed all-optical data communications. Any traffic demand passing …

The paper investigates efficient allocation of three types of flows (unicast, anycast, multicast)
in elastic optical network with dedicated path protection. We model the problem as an …

We consider the routing and spectrum allocation (RSA) problem of protecting all-optical
multicast sessions against a single link failure in elastic optical networks (EONs). A tree is …

In an elastic optical network, it is critical to protect a multicast request against any single link
failure with minimum spectrum consumption. However, conventional single light-tree based …

Internet traffic is experiencing an enormous growth and increased demand for new services.
To enhance flexibility and improved spectral efficiency of traditional WDM optical networks …

Driven by increasing user requirements and expectations, the fast development of
telecommunications networks brings new challenging optimization problems. One of them is …

Given the importance of multicast traffic in current optical networks, many effective multicast
routing and spectrum assignment (MRSA) algorithms have been proposed to achieve …
