摘要
This paper presents a dimensioning approach tailored to hierarchical dual-homing multi-ring architectures with and without wavelength converters. Analytical lower bounds based on cutsets are applied in order to allocate the traac to the individual rings eeciently, as well as to estimate the number of required bres per ring. The use of these bounds also facilitates the evaluation of the proposed methods. The eeect of using a hierarchical bre distribution , which allocates a larger number of bres in more heavily loaded rings, is studied. Further, the impact of topology and network connectivity on wavelength and hardware requirements is investigated considering various multi-ring topologies.
