Abstract
Systems and methods for scalable SDN devices having ports/network interfaces mapped to cardinal flow processing (CFP) units are provided. According to one embodiment, an incoming packet is received, at a software-defined networking (SDN) switch. An ingress port on which the incoming packet was received is determined. A cardinal direction to which the ingress port is mapped is determined. Based on the determined cardinal direction, the SDN switch identifies a cardinal flow processing (CFP) unit within the SDN switch with which the determined cardinal direction is associated. The SDN switch then causes the incoming packet to be processed by the identified CFP unit.
