—In this paper, the optical composite burst switching (OCBS) technique is proposed to be implemented in an all-optical backbone network to support Internet protocol (IP) traffic. The OCBS is based on two main features. First, several IP packets are assembled in a single macropacket, called burst. Second, the burst contention in an optical switch is handled(More)
In this paper we study the Optical Burst Switching (OBS) paradigm for the support of the TCP flows in an All Optical Network (AON). We analyze the TCP send rate, i.e. the amount of data sent per time unit, taking into account of: i) the burst assembly mechanism, called burstification process; ii) the burst loss events inside the OBS network. The goals of(More)
An architecture is proposed for a Wavelength Division Multiplexed (WDM) optical packet switch equipped with both limited range wavelength converters (LRWCs) and shared full range wavelength converters (FRWCs). The FRWCs are used to overcome the performance degradation in terms of Packet Loss Probability due to the use of LRWCs only. A probabilistic model is(More)
—In this paper, we propose an architecture for a buffer-less packet optical switch employing the wavelength dimension for contention resolution. The optical packet switch is equipped with tunable wavelength converters shared among the input lines. An analytical model is proposed in order to determine the number of converters needed to satisfy prefixed(More)
— Coupling MPLS Traffic Engineering on top of a wavelength-routed WDM layer offers great flexibility to operators to allocate traffic demands in their networks. In this paper we consider the problem of off-line joint configuration at both packet and optical layers. We consider time-variant offered traffic, and assume that the operator has knowledge of the(More)
This paper deals with the comparison between two resource reservation techniques, named Tell and Go (TG) and Tell and Wait (TW), when they are used in an All Optical Network for the support of high-speed IP traffic. This comparison study is motivated considering that the modes currently under investigation for the implementation of the next generation(More)
