Abstract: A software switch for providing a network function and an operation method thereof are provided. The software switch includes an extraction unit configured to, when a packet is received, extract packet header information from the received packet, a search unit configured to search for an identical flow rule among pre-determined flow rules based on the extracted packet header information, a performance unit configured to, when the identical flow rule is found, execute actions in which a network function for the found flow rule is previously defined, and a transmission unit configured to transmit a packet in which the actions are executed to a destination.
