The problem of routing and wavelength assignment (RWA) is critically important for
increasing the efficiency of wavelength-routed all-optical networks. Given the physical …

We provide network designs for optical add-drop wavelength-division-multiplexed (OADM)
rings that minimize overall network cost, rather than just the number of wavelengths needed …

To overcome the inefficiency of the rigid frequency allocation in traditional wavelength
division multiplexing (WDM) networks, the idea of slicing the optical spectrum for elastic and …

In this paper, we consider traffic grooming in WDM/SONET ring networks when the offered
traffic is characterized by a set of traffic matrices. Our objective is to minimize the cost of …

The recent decade has witnessed a tremendous growth of Internet traffic, which is expected
to continue climbing for the foreseeable future. As a new paradigm, Spectrum-sliced Elastic …

We focus on wavelength allocation schemes for all-optical WDM ring networks. For an N
node network we characterize the traffic by its load L/sub max/(the maximum number of …

In this paper, we propose a general scheduled traffic model, sliding scheduled traffic model.
In this model, the setup time t/sub s/of a demand whose holding time is T time units is not …

Optical add/drop multiplexers (OADMs) can significantly reduce the cost of metro optical
wavelength-division multiplexing (WDM) ring networks by allowing traffic to bypass …

We consider the problem of wavelength assignment in reconfigurable WDM networks with
wavelength converters. We show that for N-node P-port bidirectional rings, a minimum …

Rerouting is a viable and cost-effective approach to decrease the blocking probability in
legacy circuit-switched networks. We study lightpath rerouting in optical WDM networks in …
