All-to-all communication for some wavelength-routed all-optical networks
This paper studies the problem of AllltooAll Communication for optical networks. In such networks the vast bandwidth available is utilized through wavelength division multiplexing (WDM) : a single physical optical link can carry several logical signals, provided that they are transmitted on diierent wavelengths. In this paper we consider allloptical (or singleehop) networks, where the informati...
متن کاملSparse-Partial Wavelength Conversion in Wavelength-Routed All-Optical Networks
Wavelength conversion has been shown as one of the key techniques that can improve the blocking performance in a wavelength-routed all-optical network. Given that wavelength converters nowadays are still very expensive, how to make effective use of the limited number of wavelength converters becomes an important issue. In this paper, we propose a novel sparse-partial wavelength conversion (SPWC...
متن کاملElimination of All-Optical Cycles in Wavelength-Routed Optical Networks
A transparent (wide-area) wavelength-routed optical network may be constructed by using wavelength cross-connect switches connected together by fiber to form an arbitrary mesh structure. The network is accessed through electronic stations that are attached to some of these cross-connects. These wavelength cross-connect switches have the property that they may configure themselves into unspecifi...
متن کاملDesign of Logical Topologies for Wavelength-Routed All-Optical Networks
This paper studies the problem of designing a logical topology over a wavelength-routed all-optical network physical topology. The physical topology consists of the nodes and ber links in the network. On an all-optical network physical topology, we can set up lightpaths between pairs of nodes, where a lightpath represents a direct optical connection without any intermediate electronics. The set...
متن کاملImpact of physical layer impairments on the all-to-all broadcast in wavelength routed optical networks
All-to-all broadcast is to disseminate a unique message from each node to every other node of the network. This paper investigates the impact of some of the physical layer impairments on the optical all-to-all broadcast in linear array, bidirectional ring and hypercube networks. The physical layer impairments include Amplified Spontaneous Emission (ASE) noise, switch induced crosstalk and demux...
