We present algorithms for the design of optimal virtual topologies embedded on wide-area
wavelength-routed optical networks. The physical network architecture employs wavelength …

We consider dynamically reconfigurable wave-length routed networks in which lightpaths
carrying IP traffic are on demand established. We face the Routing and Wavelength …

In the past few years, there has been growing interest in wide area\All Optical Networks" with
wavelength division multiplexing (WDM), using wavelength routing. Due to the huge …

A wide-area transparent optical network can be constructed by using wavelength routers
and switches, each dealing with only a small number of wavelengths. In this work we …

We introduce the concept of a light-tree in a wavelength-routed optical network. A light-tree
is a point-to-multipoint generalization of a lightpath. A lightpath is a point-to-point all-optical …

We consider the problem of designing a logical optical network topology for a given physical
topology (or fiber layout) and a given traffic demand matrix between the end-users. Traffic …

We explore design principles for next-generation optical wide-area networks, employing
wavelength-division multiplexing (WDM) and targeted to nationwide coverage. This optical …

Consider an optical network which employs wavelength-routing crossconnects that enable
the establishment of wavelength-division-multiplexed (WDM) connections between node …

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 …
