Abstract:

In this paper wavelength converter is demonstrated to reduce call blocking. When a light path is established same wavelength has to be allocated on all the fibre links, this is wavelength continuity constraint. To overcome this constraint, wavelength converter is used. This paper gives the performance of the network in terms of blocking probability, throughput, and grade of service, for no wavelength conversion, sparse partial wavelength conversion and full wavelength conversion. It also shows that the performance of sparse partial wavelength conversion is closer to full wavelength conversion. Thus this reduces the number of wavelength converters and makes the conversion more cost effective.

Keywords:

wavelength converter, wavelength continuity constraint, call blocking, sparse partial wavelength conversion.
