This work proposes a quality of service differentiation algorithm, improving the service class granularity and isolation of our recently presented waveband plane based design. The design aims at overcoming potential hardware limitations and increasing the switch node dimensioning flexibility in core networks. Exploiting the wavelength dimension for contention resolution, using partially shared wavelength converter pools, avoids optical buffers and reduces wavelength converter count. These benefits are illustrated by numerical simulations, and are highlighted in a dimensioning study with three service classes.
