Dimensioning of FDL Buffers for Optical Burst Switching Nodes
Optical burst switching (OBS) is a promising candidate for a more dynamic optical layer in the context of IP over WDM. Although buffering is not mandatory for the functionality of OBS, even simple FDL buffers can improve burst loss probability. In this paper, we first discuss principal buffer architectures and reservation schemes for fiber delay line (FDL) buffers. Then, we investigate key desi...
متن کاملOptical Packet Switched Networks with Recirculating FDL Buffers
The major goal of Optical Packet Switching (OPS) is to match switching technology to the huge capacities provided by (D)WDM. We study optical packet switches with recirculating FDL buffers by comparing different FDL configurations and analysing buffer scheduling strategies in order to exploit the FDL buffer as efficiently as possible: through simulation, we assess the logical performance focusi...
متن کاملImpact of Burst Assembly on the Performance of FDL Buffers in Optical Burst-Switched Networks
Optical burst switching (OBS) is a new approach proposed with the objective of utilizing the huge transmission capacity available with WDM links both efficiently and cost effectively. Burst assembly is one of the main building blocks of this approach, which is performed at the edge of an OBS domain in order to generate bursts whose lengths are much larger than the switching time of all-optical ...
متن کاملAnalysis of an Asynchronous Single-Wavelength FDL Buffer
We investigate the behaviour of an asynchronous single-wavelength fiber delay line (FDL) buffer by means of a continuous-time queueing model. Through a limit procedure, previously obtained results for a discrete-time queueing model are translated to a continuous-time setting. The two important cases of exponentially distributed burst sizes and deterministic burst sizes are discussed in detail. ...
متن کاملBurst rescheduling with wavelength and last-hop FDL reassignment in WDM optical burst switching networks
In this paper, we consider the problem of fast and efficient dynamic scheduling of bursts that belong to different classes of priority in wavelength-division multiplexing (WDM)based optical burst switching (OBS) networks with limited optical buffers. In OBS networks, control and data components of a burst are sent separately with a time gap to ensure that resources such as wavelengths and fiber...
