摘要： PROBLEM TO BE SOLVED: To automatically and properly select a link used in each hop of the communication path and an adaptation at the boundary between management domains or layers according to service type and maintenance requirements without complicating a control sequence in an MPLS (Multi-Protocol Label Switching Architecture)/GMPLS (Generalized Multi-Protocol Label Switching Architecture) network. SOLUTION: Firstly, a means for appending an identifier of a service to be provided and attributes of the service to a communication path establishment control message to request to establish the path is installed in a source node. Secondly, a means for determining the maintenance requirements and adaptations of the communication path based on the service identifier and/or the service attribute is installed in each node. Thirdly, maintenance attributes of network resources are compared with the maintenance requirements to determine links and nodes through which the communication path passes. The determined links, nodes and adaptations are set as action parameters of a switch unit and/or an interface unit. COPYRIGHT: (C)2010,JPO&INPIT
