PURPOSE:To improve the economy and communication capability of a label multiplex communication network with respect to the improvement of the virtual path setting system in the label multiplex communication network. CONSTITUTION:When communication with a virtual exchange (non-connection exchange) not connected by a direct virtual path VP is requested, relay connection from a virtual channel exchange with direct VP set to the unconnection exchange using a set VP is requested to each virtual channel exchange 100, and when the relay connection is accepted, the communication requested by the relay connection is started, and when the relay connection is rejected, the setting of direct VP to the unconnection exchange is requested to a virtual path exchange 200 by the provision of a connection request means 101 setting a VC to the unconnection exchange on the set direct VP and a relay connection setting means 102 setting relay connection when the relay connection requested by other exchange is available.
