Abstract
This application discloses a flow table processing method and the method is applicable to a software-defined networking SDN. After determining that M virtual machine ports are added to a security group, an SDN controller generates a first matching flow table set, a second matching flow table set, and an action flow table of the security group. The first matching flow table set and the second matching flow table set together implement matching of the security group. The action flow table of the security group includes a packet action for a packet that successfully matches the security group. The method provided in this application lowers complexity of a flow table used to implement security group matching, and improves security group matching efficiency.
