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 high-speed SONET/WDM rings, the dominant system cost may be the cost of electronic
components, or in other words, the cost of SONET ADMs (S-ADMs). The number of S-ADMs …

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

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 …

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 …

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 …

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

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 …

We address the problem of traffic grooming in WDM rings with all-to-all uniform unitary traffic.
We want to minimize the total number of SONET add-drop multiplexers (ADMs) required. We …

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 …
