The recent improvements in broadband networks are enabling network carriers and providers to provide MultiProtocol Label Switching (MPLS) - based dedicated services for enterprise customers. These dedicated services will be widely introduced in interconnected networks to meet the demand of enterprise customers. Since end-to-end connection will be more complicated in interconnecting networks, path (end-to-end route) management will be important to enable quick reaction to failures to ensure customer satisfaction. The authors propose a path management method in MPLS networks, which is combined with the following two methods. A method in which a link stores an adjacent link identifier and the edge node identifier is stored at an edge link. A method in which all links store edge node identifiers.
