In this paper, we propose a controlled retransmission scheme in optical burst switching
(OBS) networks. Different from previous works in the literature, we set a different value to …

Fibre delay lines (FDLs) can substantially reduce the burst loss in Optical Burst Switching
(OBS) networks and share-per-node FDL configurations can provide a more cost-efficient …

This paper presents an efficient and accurate mathematical method to evaluate the blocking
probability of burst loss in dynamic WDM networks with wavelength conversion. The …

Optical buffering based on fiber delay lines (FDLs) has been proposed as a means for
contention resolution in an optical packet switch. In this article, we propose a queuing model …

The realisation of optical network architectures may hold the key to delivering the enormous
bandwidth demands of next generation Internet applications and services. Optical Burst …

We propose an approximate modelling method for analysing networks of optical burst
switches with shared fibre delay lines (FDLs). To achieve a good accuracy in evaluating …

Recently, high port-count optical packet switches, based on the Arrayed Waveguide Grating
