We consider the problem of constructing logical topologies over a wavelength-routed optical
network with no wavelength changers. We present a general linear formulation which …

This article addresses the problem of finding a static virtual topology design and flow routing
in transparent optical wavelength division multiplexing networks under a time-varying …

Hybrid hierarchical optical cross-connects enhance the performance/cost ratio of optical
networks by providing transparent (optical) switching of sets of wavelengths (wavebands) in …

As traffic volumes carried by optical networks continue to grow by tens of percent year over
year, we are rapidly approaching the capacity limit of the conventional communication band …

This paper describes ongoing work in the design and analysis of the Wavelength-Division
Optical Network (WON). The WON is a multichannel, multihop lightwave network suitable for …

An overview of characteristics and challenges of photonic packet switching is given,
illustrating its potential advantages within future nodes and networks, then describing basic …

We present a topology design methodology for broadband (FTTx) access networks. The
calculations are based on real geographic data (digital maps) and infrastructural information …

We consider the problem of designing a network of optical cross-connects (OXCs) to provide
end-to-end lightpath services to large numbers of label switched routers (LSRs). We present …

Several government-and industry-funded prototyping and development activities in WDM
optical networks are being conducted at various R&D centers. Optical networks can be …

We address the problem of generating physical realistic optical transport network topologies.
This type of network has characteristics that differ from scale-free networks, such as the …
