Abstract
Various exemplary embodiments relate to a method for processing data packets by a first-hop switch in a data network, including: receiving a first data packet associated with a flow; determining whether the flow associated with the first data packet is found in a flow table in the first-hop switch; modifying the first data packet by replacing a packet header field with flow definition information; and transmitting the modified first data packet based upon the flow definition information.
