FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a communication unit, a communication system, a communication method for measurement of state of a communication route. The communication system contains an adder section, a measurement section, a section of notification on measurement results, a processing rule storage section and a processing section. The adder section adds data for measurement of the communication state to the reception frame when the communication unit is an input boundary node of a network. The measurement section measures the communication state on the basis of data of measurement of the communication state when the communication unit is an output boundary node of a network. The section of notification notifies on measurement result the control unit which controls a network. The processing rule storage section addresses to data of the reception frame identifier and saves the processing rule, correlating the data of identification of the reception frame and processing of the reception frame. The processing section processes the reception frame on the basis of the processing rule.
EFFECT: possibility to switch a route at a high rate by means of server control according to network communication network.
