Reliability Specification of Telecommunication Networks Based on the Failure Influence by Using Evolutional Algorithm

For the first step of the reliability design of telecommunication networks, the reliability requirements should be determined. The method to determine the reliability requirements which takes account of the social loss caused by service outage has been established for telephone network in Japan. The feature of above method is to determine the reliability requirement of network element by solving the equation between the loss and reliability of the simple structure of networks, i.e. subscriber areas or transit lines. Therefore, the previous method cannot be applied for the general structure of networks, i.e. the NGN architecture consisted of various control equipment. This paper has investigated the possibility to determine the reliability requirement of network element evolutionally by allocating the traffic demand and the loss caused by failure to the concerned element.
