N2 - This paper focuses on dimensioning resilient, hierarchical, dual-homing, multi-ring architectures with or without wavelength converters. A novel dimensioning approach is presented to distribute traffic load between individual rings with the use of appropriate cutset-based analytical lower bounds. Evaluation of the proposed methods is facilitated by equivalent integer linear programming formulations tailored to multi-ring networks. Results obtained for structures adopting different interconnection schemes reveal that topology is a critical factor for both wavelength and hardware requirements.
