Abstract
A communications network system, which is comprised of a management network, a control network, and a user transmission network, includes signaling-based communication apparatuses, each consisting of a control node and a communication node, and non-signaling-based communication apparatuses without having associated control nodes. In this system, a path can be established in a user data transmission network by controlling a signaling process on the control network. The configuration of the communication node of the non-signaling-based communication apparatus is changed by a network management system provided in the management network, while the configuration of the communication nodes of the signaling-based communication apparatus are changed by the associated control nodes by successively transmitting a signaling message to the next control node on the control network.
