Abstract
A communication apparatus is provided with: a processing rule storage unit capable of storing a first processing rule for unknown packets set in advance, and a second processing rule set by a control apparatus; a packet processor that processes received packets based on processing rules stored in the processing rule storage unit; and a state notification unit that transmits a predetermined control message to the control apparatus when a packet is processed using the first processing rule. On receiving the predetermined control message, the control apparatus creates the second processing rule to be set in the communication apparatus and sets the second processing rule in the communication apparatus, and also discards packets included in the control message. The communication apparatus continues packet processing using the first processing rule until the second processing rule is set by the control apparatus.
