Title: DEVICE AND METHOD FOR COMMUNICATION NETWORK
Abstract:
In the present invention, a control device (40) is configured to acquire a required end-to-end performance which is required of an end-to-end path from a first end node to a second end node, and to determine a required segment performance required for each path segment on the basis of the required end-to-end performance. The control device (40) is further configured to communicate with an entity that controls the path segments or nodes included in the path segments, in order to implement the required segment performance in the corresponding path segment. The control device (40) is further configured to update, on the basis of the achievement status of the required segment performance in the path segments, the required segment performance currently being implemented in at least one path segment. Due to this configuration, the present invention can contribute to guaranteeing a required end-to-end performance even if the quality of path segments changes, for example.
