Patent attributes
In a node device having a function of recognizing route information of a network, a route selector selects a connection setting route based on the dynamic route information of the network, and generates a reservation request of a predetermined optimum route unless the connection setting route is the predetermined optimum route, a route switchover reservation portion monitors whether or not the predetermined optimum route becomes available based on the route information during the communication, and makes switchover instructions toward the predetermined optimum route to a call processor. The call processor sets a connection in a selected connection setting route, and sets another connection in the predetermined optimum route by the switchover instructions.
