While optical-transmission techniques have been researched for quite some time, optical"
networking" studies have been conducted only over the past dozen years or so. The field …

The transmission capacity of a link in today's optical networks has increased significantly
due to wavelength-division multiplexing (WDM) technology. The network performance is …

Traffic grooming refers to techniques used to combine low-speed traffic streams onto high-
speed wavelengths in order to minimize the networkwide cost in terms of line terminating …

The emergence of wavelength-division multiplexing technology has led to a tremendous
increase In the available transmission capacity in wide area networks. Consequently, these …

In high-speed SONET rings with point-to-point WDM links, the cost of SONET add-drop
multiplexers (S-ADMs) can be dominantly high. However, by grooming traffic (ie …

In this paper, we consider the traffic grooming, routing, and wavelength assignment (GRWA)
problem for optical mesh networks. In most previous studies on optical mesh networks, traffic …

We consider the problem of designing a virtual topology to minimize electronic routing, that
is, grooming traffic, in wavelength routed optical rings. The full virtual topology design …

Traffic grooming is the term used to describe how different traffic streams are packed into
higher speed streams. In a synchronous optical network-wavelength division multiplexing …

The Internet revolution. Once, the public was delighted with 14.4 modem access and
fascinated by low-tech Web site content. But not for long. Technology has raced to keep up …

SONET add-drop multiplexers (ADMs) are the dominant cost factor in the SONET/WDM
rings. They can potentially be reduced by optical bypass via optical add-drop multiplexers …
