Optical networks and the related technologies, network management software and services
have undergone remarkable developments, and such networks are now the ultra-high …

Traffic grooming is a central problem in optical networks. It refers to packing low rate signals
into higher speed streams, in order to improve bandwidth utilization and reduce network …

SONET ADMs are dominant cost factors in WDM/SONET rings. Whereas most previous
papers on the topic concentrated on the number of wavelengths assigned to a given set of …

We study traffic grooming in optical network design, where the goal is to aggregate low-
bandwidth traffic streams to utilize efficiently high-bandwidth media such as wavelength …

In a WDM network, routing a request consists in assigning it a route in the physical network
and a wavelength. If each request uses at most 1/C of the bandwidth of the wavelength, we …

In a WDM network, routing a request consists in assigning it a route in the physical network

The problem of grooming is central in studies of optical networks. In graph-theoretic terms,
this can be viewed as assigning colors to the lightpaths so that at most g of them (g being the …

A central problem in optical networks is to assign wavelengths to a given set of lightpaths, so
that at most g of them that share a physical link get the same wavelength (g is the grooming …

We consider the problem of switching cost in optical networks, where messages are sent
along lightpaths. Given lightpaths, we have to assign them colors, so that at most g …

This paper contributes to the field of test engineering: it shows the tradeoffs and engineering
aspects of a low-cost, flexible SRAM MBIST engine, applied to the 768 and 256 byte SRAMs …
