For decades, optical networks have provided larger bandwidths than could be utilized, but
with the increasing growth of the global Internet traffic demand, new optical transmission …

Traffic grooming can effectively utilize the transmission capacity of WDM networks by
properly multiplexing low-speed traffic flows onto high-capacity wavelength channels. In …

In many modern networks, such as datacenters, optical networks, and multiprotocol label
switching (MPLS), the delivery of a traffic flow with a certain bandwidth demand over a single …

A new all-optical node architecture, known as POADM, may lead to a considerable cost
reduction for the infrastructure of the rings ensuring at the same time their excellent …

Traffic grooming has become a very important issue in optical networks as optical networks
provide a very high speed of data transmission for huge amount of data. These are useful for …

Hierarchical traffic grooming facilitates the control and management of multigranular WDM
networks. We define the hierarchical virtual topology and traffic routing (H-VTTR) problem …

The subject of this thesis concerns algorithmic aspects of energy-related trends in
computation. Within recent years, the computationally heaviest jobs are executed over …

Traffic grooming refers to a class of optimization problems developed to address the gap
between the wavelength capacity and the traffic demands of individual connections in …
