Summary:
This paper proposes a new measure of cascading failures in telecommunications networks, where cascading failures are wide area damages caused by a small size triger failure. Previous works do not consider the probability of such cascading failures appear. Now this paper propose a new measure to evaluate such probability. Key idea is that we do not use traditiona reliablity measure availablity because it needs information of repair time while such repair tiime is difficult to estimate in real situation. Our measure cascadifng failure rate is defined as the inverse of mean time to first cascading failure, where we do not need information of repair time.
