Abstract
In one embodiment, a packet is processed by three flow tables in a network device of a software-defined networking (SDN) system. In the first flow table, upon finding a match based at least partially on an IP address value of the packet, the network device adds a first identifier based on the IP address value to metadata of the packet and forwards the packet to a second flow table, where upon finding a match based at least partially on a port value of the packet, the network device adds a second identifier based on the port value to the metadata and forwards the packet to a third flow table. At the third flow table, upon finding a match based at least partially on a combination of the first and second identifiers, the network device performs one set of instructions of the matching entry on the packet.
