We present a review of the integer linear programming (ILP) formulations that have been
proposed for the routing and wavelength assignment problem in WDM optical networks …

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 …

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 …

Understanding the variability of Internet traffic in backbone networks is essential to better
plan and manage existing networks, as well as to design next generation networks …

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 paper proposes an optimal design scheme for survivable wavelength-division
multiplexing (WDM) transport networks in which fast restoration can be achieved by using …

Wavelength-division multiplexing (WDM) networks are believed to be a promising candidate
to meet the explosive increase of bandwidth demand in the Internet. In this article, we survey …

In this paper we discuss the optimal design of logical topologies in alloptical WDM networks.
We rst explain the key aspects of the problem, and provide a mixed integer linear …

Transport networks evolved from DCS (Digital Cross-connect Systems)-based mesh
architectures, to SONET/SDH (Synchronous Optical Networking/Synchronous Digital …

The bandwidth requirements of the Internet are increasing every day and there are newer
and more bandwidth-thirsty applications emerging on the horizon. Wavelength division …
