| Abstract(in English) | High reliability is required for communication network which is one of important social infrastructure. It is necessary to continue communication even after some equipment failure due to disaster, so that communication networks have been designed by considering connectivity, a measure of reliability, so far. However, a big change from telephone networks to the Internet has brought a diversity of the definition of reliability required for communication networks. For example, recovery scheduling has not considered intermittent link failures, so that, if link failures are occurred, it is assumed that the failed links are recovered immediately. However, indeed, there is a possibility that network failures occur by an aftershock. In such a case, material resource and human resource are restricted, so that it is necessary to determine an appropriate recovery order of the failed links. Therefore, the definition of reliability considering intermittent link failures is also needed. New network design problems according to the diversity of the definition of reliability must be studied, and efficient algorithms to solve the problems must be developed. In this paper, we introduce some new definitions of reliability and overview various reliable network design problems and related results. |
