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 evolution of generational networks has stimulated the growth of delay-sensitive traffic,
destabilizing the already incapacitated existing network infrastructure. Due to time …

In this letter, we propose three new approaches to optimizing multicast traffic in elastic
optical networks that implement distance-adaptive transmission. Two of the approaches are …

Next generation optical networks will require high levels of flexibility both at the data and
control planes, being able to fit rate, bandwidth, and optical reach requirements of different …

A multiflow transponder in flex-grid optical networks has recently been proposed as a
transponder solution to generate multiple optical flows (or subcarriers). Multiflow …

We present the design and experimental evaluation of an Optical Multicast System for Data
Center Networks, a hardware-software system architecture that uniquely integrates passive …

New applications require conveying huge bitrate from a source node to multiple
destinations. As a result, point-to-multipoint (P2MP) connections need to be established on …

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

In this paper, a reactive defragmentation rerouting and spectrum assignment (RDRSA)
strategy when existing connection requests terminated and network resources released 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 …
