Packet Pacing in Small Buffer Optical Packet Switched Networks

Keeping the packet sequence in optical packet-switched networks

This paper deals with optical packet switches with limited buffer capabilities, subject to asynchronous, variable-length packets and connection-oriented operation. The focus is put on buffer scheduling policies and queuing performance evaluation. In particular a combined use of the wavelength and time domain is exploited in order to obtain contention resolution algorithms that guarantee the seq...

Altınkaya and Şevket Gümüştekin for serving on my thesis committee. Their advice and comments are greatly appreciated. I would like to thank my colleagues for supplying me various documents and my wife Berna, being always by my side. Finally, I would like to dedicate this thesis to the memory of my father to whom I learnt patience. iv ABSTRACT Ever-increasing demand for high capacities brought ...

Optical Label Switching Technologies for Optical Packet Switched Networks

All-optical add-drop node for optical packet-switched networks.

We have demonstrated all-optical packet add-drop for all-optical packet-switched networks. Intelligent all-optical add-drop of packets is performed, based on all-optical processing of packet headers. The header and payload rates are 5 and 10 Gbits/s, respectively.

Ingress Traffic Conditioning in Slotted Optical Packet Switched Networks

Optical Packet Switched (OPS) networks are known to suffer from high packet losses due to contentions. Techniques such as fiber delay line (FDL) buffering and wavelength conversion help to relieve contentions to an extent, but are expensive and are therefore used sparingly. This paper explores how electronic edge nodes can condition the traffic entering the OPS network with the objective of uti...
