DISTRIBUTION TYPE FAULT RECOVERY DEVICE, SYSTEM AND METHOD, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a distribution fault recovery device that can execute fault recovery processing in a short time with a high fault recovery rate. SOLUTION: A load distribution path calculation means 5 selects a path with a high load distribution effect from an object path database 10 as a path for connection set normally and sets the connection, so as to use a link resource in a way that links with a high load are not biased. Furthermore, a load distribution recovery path calculation means 11 selects a path with a high load distribution effect from the object path database 10 as a path for a recovery connection for the connection disconnected by a fault and sets the recovery connection, to prevent the recovery connection from concentrating on a link.
