SDN Method for applying flow rule in Software Defined Networking environment and apparatus therefor

摘要

The present invention relates to a method and apparatus for collectively applying a flow rule to each SDN domain in an SDN environment. According to an embodiment of the present invention, an apparatus for applying a flow rule to each SDN domain in a Software Defined Networking (SDN) environment includes: a rule application unit configured to transmit a dummy flow rule to an SDN controller of each domain; and an activation time calculation unit configured to set an activation time of the actual flow rule based on the longest required time among the received required times when the required time required for the dummy flow rule to be applied in the domain is received from the SDN controller of each domain. do. The rule application unit transmits the set activation time and the actual flow rule to the SDN controller of each domain, and applies the actual flow rule to each domain at the activation time.
