Switched DWDM Ethernet Passive Optical Networks

The IEEE Ethernet Passive Optical Networks (EPON) standard is a leading Time Division Multiplex (TDM) standard for PONs. The paper investigates the operation of an EPON based system in a Dense Wavelength Division Multiplex (DWDM) environment. It extends the concept of a multi-wavelength system from being merely a stack of independent PONs to that of a stack of a switched set of PONs. The functi...

Investigation of Various Throughput Improvement Techniques in DWDM Optical Networks

When the information is transmitted over the network there are various reasons due to which there is loss of information. Some time due to congested networks the loss is more in the optical networks. As a result we need an intellectual algorithm or process which is applied to the network so that the network could overcome the congestion. In this paper, we study the various techniques applied to...

Dynamical Configuration of Transparent Optical Telecommunication Networks

Acknowledgements The research presented in this thesis is motivated by a joint project of T-Systems Nova GmbH Technologiezentrum and the Konrad-Zuse-Zentrum für Informationstechnik Berlin, financed by Deutsches Forschungsnetz e.V. Working on this project was very instructive for me. The cooperation with Jörg Rambau, Diana Poensgen and Sven O. Krumke was very pleasant. I wish to thank them for t...

Service Differentiation in IP over DWDM Optical Networks

Recent developments in optical devices and communication protocols have made possible real-time provisioning in DWDM optical networks without human intervention. In order to provide an end-to-end optical path for an IP client, the widely known Routing and Wavelength Assignment (RWA) problem must be solved. In this paper we introduce a new RWA procedure meant to support different classes of serv...
