FIELD: communication.SUBSTANCE: invention relates to communication. Communication device is equipped with a processing rule storage unit for storage of a first processing rule for unknown packets, specified in advance, and a second processing rule set by control device; a packet processing unit, which processes received packets based on processing rules, stored in processing rule storage unit; and a status notification unit, which transmits a predetermined control message to control device, when packet is treated using first processing rule. When receiving specified control message, control device generates a second processing rule which must be set in communication device, and sets second processing rule in a communication device, and also discards packets included in control message. Communication device continues processing of packets using first processing rule until second processing rule is set by control device.EFFECT: technical result is reduced load on corresponding devices in network with centralised control, when a large amount of data is input and stops inversion of order of packet transmission.10 cl, 9 dwg |
