REDUCTION OF BLOCKING PROBABILITY OPTIMIZATION ALGORITHM FOR ALLOCATION OF WAVELENGTH CONVERTER
*Dr. Shruthi P. C. and Dr. Sivakumar B.
In all-optical network, the Wavelength conversion is one of the key that has been shown to improve blocking performance in a wavelength-routed. In this paper the different techniques Partial Wavelength Conversion, Sparse Wavelength Conversion are analyzed. A performance indication of an All Optical Network is the call blocking probability. The blocking probability is reduced at an affordable cost and at the same time to make sure that other performance measures are within reasonable limits is also achieved. The blocking probability is calculated varying number of channels and load (in Erlangs) on each link in network. It has been observed that the selection of nodes to be equipped with wavelength converters is crucial. The blocking probability should be minimal at those particular nodes chosen to place the Wavelength Converter. The placement of Wavelength Converter will be easy for the decrease in the blocking probability by a large margin. In this paper, Sparse-Partial Wavelength Conversion (SPWC) network architecture is proposed to support wavelength conversion. The performance of an different Optical backbone Network for different parameters such as number of links, number of channels, number of Wavelengths associated between source to destination are analyzed.[Full Text Article]
