We consider the problem of grooming traffic in WDM star and tree networks to minimize
equipment cost. We prove an important result regarding wavelength assignment in both …

The widespread deployment of WDM optical networks posts lots of new challenges for
network designers. Traffic grooming is one of the most common problems. Efficient grooming …

Traffic grooming in WDM networks is obtained by intelligently allocating the traffic onto a
given set of wavelengths. This paper presents heuristics for grooming of non-uniform …

The traffic grooming, routing and wavelength assignment (GRWA) problem in wavelength
division multiplexed networks is addressed. A new heuristic algorithm, the GRWABOU …

Much work has focused on traffic grooming in SONET/WDM ring networks. Previous work
has considered many aspects of traffic grooming, including minimizing the number of ADMs …

This chapter presents a comprehensive survey on various works done in the field of
wavelength division multiplexing based optical networks. We start with a brief introduction of …

In this paper we focus on the problem in optical networks in which selfish or non-cooperative
users can configure their communications so as to minimize the cost paid for the service …

We consider a problem which arises in optical routing. WDM/SONET rings are a network
architecture used by telecommunications carriers for traffic streams. The dominant cost factor …

We consider the problem of grooming paths in all-optical networks with tree topology so as
to minimize the switching cost, measured by the total number of used ADMs. We first present …

High speed SONET rings are widely used as network infrastructure. In WDM/SONET rings,
the SONET add/drop multiplexers (SADMs) can significantly increase the overall system …
