In this comment, we present some remarks on the availability evaluation of overlap dedicated segment protection (o-DSP) method in Tornatore et al., 2010, Availability Formulations for Segment Protection" . We show how to correctly apply the pivotal decomposition availability-evaluation method in directed graphs (which was claimed to inapplicable in ), such that it gives the same (exact) connection availability value as the generating function method proposed in the original paper.
