The wavelength conversion is regarded as an effective way to resolve the optical packet contention in the wavelength domain.A resolution scheme,based on shared limited range wavelength converters(LRWCs) combined with shared parametric wavelength converters(PWCs),is proposed in this paper for all-optical packet wavelength resource confliction.The parametric wavelength converter(PWC) priority algorithm is put forward as a resolution scheme for the wavelength contention in the optical packet switch...
