ABSTRACT:
A signaling apparatus is applied to a node constituting a network including internal network to network interface (INNI) domains having INNI interfaces between a plurality of networks in an area and external network to network interface (ENNI) domains having ENNI interfaces that connect the INNI domains. The apparatus includes a processing unit that processes a signaling message for setting a path when an end-to-end path that passes through the INNI domains and the ENNI domains that connect the INNI domains is set in response to the signaling message, a storing unit that holds information on types of links between an own node and adjacent nodes, and a judging unit that judges whether the own node is a connection end point of the INNI domains or the ENNI domains with reference to route information in the message and the information on the types of the links held in the storing unit.
