The advent of fiber optic transmission systems and wavelength division multiplexing (WDM)
have led to a dramatic increase in the usable bandwidth of single fiber systems. This book …

Coupling MPLS traffic engineering on top of a wavelength-routed WDM layer offers great
flexibility to operators to allocate traffic demands in their networks. We consider the problem …

We address the problem of designing a network built on several layers. This problem occurs
in practical applications but has not been studied extensively from the point of view of global …

For intra-domain routing, open shortest path first (OSPF) is the most commonly used
protocol. In OSPF, traffic is routed using paths that are shortest with respect to a set of link …

Telecommunication transport networks consist of a stack of technologically different
subnetworks, so-called layers, which are strongly interdependent. For example, one layer …

This paper proposes an offline solution for global path provisioning in new-generation
optical networks based on the generalized multiprotocol label switching (GMPLS) paradigm …

We study the problem of routing and wavelength assignment (RWA) in a WDM optical
network under different hop assumptions, ie, with and without wavelength converters …

We study routing and wavelength assignment (RWA) tasks in WDM mesh networks with
wavelength conversion capabilities. For each lightpath request, we solve the routing and …

This paper reports on a novel strategy and related algorithm for realizing dynamic routing
and grooming into wavelengths of data flows (label switched paths, LSPs) in new generation …

In this paper, we analyze the performance of WDM networks with traffic grooming
capabilities supporting low-rate circuit-switched traffic streams. Traffic grooming in WDM …
