This paper presents performances of a scheme that increase possibility to convert wavelengths using the existing resources in an optical packet switch (OPS) with parametric wavelength converters (PWCs). It is called a recursive parametric wavelength conversion (RPWC). A pump wavelength is used to define the original and converted wavelengths, called wavelength conversion pairs, in a PWC. Although wavelengths at the requested output fiber are available, none of PWCs can support the requests. Some packet losses may occur. Several conversion pairs are, sometime, wasteful since they are not utilized. In RPWC, unused conversion pairs are used to create additional conversion pairs. The OPS allows each wavelength to be converted using combination of unused conversion pairs using more than one PWCs, instead of using only a single PWC as in a conventional scheme. Numerical results via simulation show that RPWC achieves lower packet loss rate than the conventional scheme. |
