In this paper, we study the impairment-aware manycast routing, modulation level, and
spectrum assignment problem in elastic optical networks. We formulate a mixed-integer …

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 …

Manycast is a point to multi-point transmission framework that requires a subset of
destination nodes successfully reached. It is particularly applicable for dealing with large …

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 …

The light-tree based multicast service aggregation (LT-MSA) scheme provides a cost-
efficient method to accommodate a large number of finer-grained multicast services in …

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 …

In this paper, we present an energy-efficient manycast routing and spectrum assignment
(EEM-RSA) algorithm in elastic optical networks supporting cloud computing applications …

Recently, optical orthogonal frequency-division multiplexing technology has attracted
intensive research interest because spectrum-sliced elastic optical networks (EONs) can be …

Elastic optical networks enter as a promising technology for the future of high-capacity
networks. Its features provide flexibility and superior scalability in spectrum allocation …

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 …
