This paper extends the modeling and analysis of packet switched multistage cube intercoimection networks to include the use of multiple-packet message formats. A multiplepacket message format is needed within an interconnection network when the message to be transmitted exceeds the network's packet size. The packet offset time is introduced and used to gauge the transmission rate differential b...
This chapter summarises the activities on optical packet switching (OPS) and optical burst switching (OBS) carried out by the COST 291 partners in the last 4 years. It consists of an introduction, five sections with contributions on five different specific topics, and a final section dedicated to the conclusions. Each section contains an introductive state-of-the-art description of the specific...
TCP's burstiness is usually regarded as harmful, or at best, inconvenient. Instead, this thesis suggests a new perspective and examines whether TCP's burstiness is useful for certain applications. It claims that burstiness can be harnessed to insulate traffic from packet reordering caused by route change. We introduce the use of flowlets, a new abstraction for a burst of packets from a particul...
This paper tries to estimate the capital investment required for the fixed-telephony network switching equipment as demanded by the fourth national development plan. As a first step, the Cobb-Douglas model is used as a successful demand forecasting model to estimate the demand over the target years. Then, an architectural plan is developed for the fixed-telephony switching network that takes in...
High performance packet switching networks are being deployed to provide sufficient data bandwidth for end users 3G services such as video streaming and broadband like data services. The use of high performance networks is, therefore, essential to the success of any 3G service. However, in practice, the deployment of High performance packet switching networks is hindered due to the improper con...
Packet and burst switching have been proposed for optical networks because they can better accommodate bursty traffic generated by IP applications. In optical packet switching networks the payload and the header of the same packet are conveyed in the same channel, while burst switching networks allow the separate transportation of the payload and the header of the same burst. In this paper we c...

The paper describes research progress in technologies and architectures that give hope to deliver truly transparent switching of optical packets. The importance of all-optical packet switching/routing for convergent next generation transport network and in particularly, for QoS packet transfer in core of future generation wireless networks is pointed out. Generic photonic packet switch/router a...
