Abstract
Described are method, devices, and systems for establishing a forwarding state for a data flow in a provided datapath by receiving a packet from the data flow that is not installed in the datapath; allocating a flow queue for the data flow; processing the packet to determine a flow entry for the data flow; queueing any subsequently received packets from the data flow to the flow queue until the flow entry is set to the forwarding state; reinjecting the packet into the datapath; dequeuing the flow queue to reinject each of the subsequently received packets into the datapath; forwarding the packet and each of the subsequently received packets to a port associated with the data flow; and updating the flow entry to the forwarding state once the flow queue is emptied.
