New and improved approaches for wavelength assignment in wavelength-continuous optical burst switching networks

CoS-oriented Wavelength Assignment Algorithm in Burst Switching Optical Networks

We present a CoS-oriented wavelength assignment algorithm for burst switching optical networks with multiple service classes. Simulation results show that CoS is realized in terms of burst blocking probability and throughput.

Performance Analysis of Continuous Wavelength Optical Burst Switching Networks

Considering the economic and technical aspects of wavelength converters, full wavelength conversion capability will not be available throughout optical networks in the foreseeable future. In this paper we have used balanced static wavelength assignment (BSWA) algorithm. It is a technique to improve the performance of an all-optical network in respect of blocking probability & other parameters t...

Routing and Wavelength Assignment in Optical Networks

A New Model for Optimal Routing and Wavelength Assignment in Wavelength Division Multiplexed Optical Networks

We consider the problem of routing and assignment of wavelength (RAW) in optical networks. Given a set of requests for all-optical connections (or lightpaths), the problem is to [a)find routes from the source nodes to their respective destination nodes, and [ b) assign wavelengths to these routes. Since the number of wavelengths is limited, lightpaths cannot be established between every pair of...

Burst 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...
