Abstract
Systems and methods for an SDN switch that provides application-based conditional forwarding and session-aware load balancing are provided. According to one embodiment, a packet is received at an input port of a Software Defined Networking (SDN) switch. The packet is forwarded by the SDN switch to a first flow processing unit (FPU) of multiple FPUs of the SDN switch. The first FPU determines whether the packet is to be tracked. And, if so, the received packet is transmitted to a second FPU of the SDN switch; otherwise, the packet is transmitted to a third FPU of the SDN switch. When the packet is received at the second FPU, the packet is conditionally forwarded by the SDN switch to an application device. When the packet is received at the third FPU, the packet is conditionally forwarded to an output port or dropped.
