摘要

The present invention relates to the art of making a connection between communication terminals, taking a quality of service (QoS) into consideration in a network formed by interconnection among a plurality of switches (element units) accommodating the communication terminals. A network monitoring control system for monitoring and controlling the whole network selects element units constituting a path for making a connection on the basis of connection setting request information, including quality information on the connection to be set up and outputted from the connection-requesting side communication terminal, and, under the control of the network monitoring control system, an element monitoring control system, for monitoring and controlling one of the selected element units as its object, controls the object element unit in cooperation with an element monitoring control system for monitoring and controlling another one of the element units, forming a part of the path and adjacent to the object element unit. The network monitoring control system is made to evaluate the result of connection setting control by the element monitoring control systems to judge whether or not it meets the quality information as a whole.
