Wavelength assignment in a WDM ring to minimize cost of embedded SONET rings
TLDR
We study WDM networks in the form of rings and higher level networks as SONET/SDH self-healing rings. Expand

Cost effective traffic grooming in WDM rings
TLDR
We provide network designs for optical wavelength division multiplexed (OWDM) rings that minimize overall network cost, rather than just the number of wavelengths needed. Expand

Quality of protection (QoP): a quantitative unifying paradigm to protection service grades
In this paper we discuss a quantitative framework for best- effort protection of the optical layer. This framework provides a way to bridge the gap between two known protection grades of fullyExpand

Combined WDM and SONET network design
TLDR
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 dominated by the SONET transmission equipment connected to the optical ring. Expand

Scheduling transmissions in WDM broadcast-and-select networks
TLDR
The authors consider all-to-all transmission schedules, which are defined to be ones that schedule a packet transmission between each input-output pair. Expand
