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)
— 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)
 Abstract—Today, backbone networks of Telecom operators deploy a large number of devices and links. This is mainly due to both redundancy purposes for network service reliability, and resource over-dimensioning for maintaining quality of service during rush hours. Unfortunately, current network devices do not have power management primitives, and have(More)
This paper analyzes a framework to offer reservation of resources and QoS guarantees according to the Resource Reservation Protocol (RSVP) paradigm in a network cloud that supports a differentiated services architecture. The key elements are: intelligent Edge Devices; a flow admission and resource allocation method involving an Admission Control Server; "(More)
