Abstract :
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” [1]. We show how to correctly apply the pivotal decomposition availability-evaluation method in directed graphs (which was claimed to inapplicable in [1]), such that it gives the same (exact) connection availability value as the generating function method proposed in the original paper.
