Abstract(in English) | A network edge system to which it accommodates logical line of a lot of users, control operation of various user protocol, and prevention of illegal traffic etc, must have high availability and maintainability for network reconfiguration. In this paper, we propose the method that each user's logical line is made to belong to two or more edge systems, and managing allocation to the user of edge resources. First, we clarify the relation between a condition of network edge redundant system ,the time to repair, and availability. We propose the state incidence rate immediately before the influence goes out to the user as a new index. And we show the maintenance operation is reduced, and setting up one alternate system for the system for tens of present one, and it is shown to be able to improve availability. Second, we describe the problem of an existing autonomous control method about the viewpoint of managing allocation to the user of edge resources. So we compare and evaluate the centralized control method with the external unit, and effectiveness is shown. |
