Abstract
A method for flow rule installation in a flow-based programmable network device, includes obtaining packet flow information that includes information about times and intervals of packet flow transmissions from data transmitting devices, programming, by a controller entity, forwarding rules into a flow table based on the packet flow information, and triggering activation of a forwarding rule programmed for a particular packet flow just-in-time before actual transmission of the particular packet flow. The flow-based programmable network device comprises input/output ports, a flow table including forwarding rules that map packet flows from data transmitting devices in the network, received on an input port, to an output port based on a packet flow matching a rule in the forwarding rules, and a state table including state entries that specify states of the packet flows.
