COLLABORATIVE OPTIMISATION METHOD, DEVICE AND SYSTEM Russian patent published in 2014 - IPC H04L12/24 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication engineering. The method involves: obtaining link information, server and bandwidth information, information on user requirements in a subnetwork, where the server and bandwidth information includes virtual server bandwidth of each external port of the subnetwork, and the virtual server bandwidth is server bandwidth outside the subnetwork, where the server bandwidth outside the subnetwork is required for the subnetwork through an external port; obtaining an optimum routing parameter and a subnetwork server selection parameter in accordance with link information, server and bandwidth information and information on user requirements; obtaining optimised input bandwidth of each subnetwork external port in accordance with the optimum routing parameter and server selection parameter; comparing the optimised input bandwidth and the virtual server bandwidth of each external port, and if the results of comparing optimised input bandwidth and virtual server bandwidth of all external port are less than a set error value, the optimum routing parameter and the server selection parameter are used in the subnetwork.

EFFECT: improved performance of the entire network.
