We provide network designs for optical add-drop wavelength-division-multiplexed (OADM)
rings that minimize overall network cost, rather than just the number of wavelengths needed …

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 …

We develop traffic grooming algorithms for unidirectional SONET/WDM ring networks. The
objective is to assign calls to wavelengths in a way that minimizes the total cost of electronic …

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

This paper considers grooming of low speed traffic into high speed lightpaths in a WDM
based optical ring with a primary goal of reducing the cost of the entire system, which is …

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 …

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 …

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 …

In wavelength-division multiplexing (WDM) optical networks, the bandwidth request of a
traffic stream can be much lower than the capacity of a lightpath. Efficiently grooming low …

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 …
