| Abstract(in English) | This paper proposes a new approach for analyzing cascading failures of telecommunications networks where this failures damage wide area of networks by a small trigger failure of component. While we already proposed an analyzing method for this type of failures considering the mitigation of traffic volume, it never considers how often such failures occur. It is true that if cascading failures occur very rare then it is not so scared. Therefore, it is very important to know how often they occur. Our new approach gives this information by computing the rates of occurrences (the mean numbers of occurrences per unit time) of cascading failures from the data of failure rates of elements. We also demonstrate some numerical examples for analyzing the effects of countermeasure of giving surplus of capacity of every element. In them, the increase of surplus gives quite different effects when we focus on different levels of seriousness of cascading failures. |
