<p>A NMS for controlling the network provides a SoftPVC connection request comprising information associated with a specified relay node to a call-out node, when setting a path passing through the specified relay node. The call-out node prepares a SETUP message comprising information associated with the specified relay node, and transmits the message to nodes existing on the post stage. Thereafter, the SETUP message reaches the call-in node through the specified relay node, to thereby perform the signaling procedure, and as a result, a path from the call-out node to the call-in node passing through the specified relay node is set and established.</p> |
