Multicasting in Multihop Optical WDM Networks with Limited Wavelength Conversion

This paper provides an overview on efficient algorithms for multicasting in optical networks supported by Wavelength Division Multiplexing (WDM) with limited wavelength conversion. We classify the multicast problems according to offline and on-line in both reliable and unreliable networks. In each problem class, we present efficient algorithms for multicast and multiple multicast and show their...

Sparse and limited wavelength conversion in all-optical tree networks

Limited Wavelength Conversion in All-Optical Tree Networks

Let T be a symmetric directed tree, i.e., a tree with each edge viewed as two opposite directed links. We consider the problem of routing arbitrary sets of connection requests in T. In all-optical communication tree networks with WDM (wavelength-division multiplexing) this is equivalent to color (assign wavelengths to) a given set of directed paths so that no two directed paths of the same colo...

Performance of All-Optical Networks with Limited-Range Wavelength Conversion

Previous works have shown that wavelength conversion can considerably improve the performance in all–optical networks. However, it is an unrealistic assumption under the current technology and wavelength conversion with a limited range, not a full range, is more promising. In this paper, we propose a new analytic approach for such networks by virtue of the layered–graph where each wavelength is...

Limited Wavelength Translation in All-Optical WDM Mesh Networks

We analyze limited wavelength translation in all-optical, wavelength division multiplexed (WDM) wraparound mesh networks, where upto W wavelengths, each of which can carry one circuit, are multiplexed onto a network link. All-optical wavelength translators with a limited translation range permit an incoming wavelength to be switched only to a small subset of the outgoing wavelengths. Although m...
