Abstract
Systems and methods for an SDN switch that facilitates forwarding/differential routing decision determination are provided. A packet is received at an input port of the SDN switch. The switch includes a first and second set of flow processing units (FPUs). The packet is forwarded to a first FPU of the first set. Based on a flow table associated with the first FPU, it is determined whether the packet is to be forwarded to a network device or an output port. The packet is received from the network device at a second FPU of the second set. Based on a flow table associated with the second FPU, it is determined whether to execute one or more instructions to forward the packet to the input or output port, or to drop or default forward the packet to the input or output port.
