Network layer packet redundancy in optical packet switched networks

Quality of service differentiation, teletraffic analysis and network layer packet redundancy in optical packet switched networks

A crucial issue in optical packet switched (OPS) networks is packet losses at the network layer caused by contentions. This paper presents the network layer packet redundancy scheme (NLPRS), which is a novel approach to reduce the end-to-end data packet loss rate in OPS networks. By introducing redundancy packets in the OPS network, the NLPRS enables a possible reconstruction of data packets th...

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...

Optical Routing in Packet Switched Networks

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 ...

WDMJTDM Optical Packet Switched Network for Supercomputing

A new optical packet switching network and its enabling technologies are investigated for implementation in a Petaflops scale supercomputer system. We capitalize on the immense bandwidth of the optical fiber interconnects by deploying WDM/TDM packet payloads. To accommodate current optical switching technologies, the routing operations in the network are drastically simplified and the need for ...
