Abstract: The present disclosure provides for methods, network devices, and computer readable storage media for packet reordering. In one embodiment, a method includes receiving a first packet of a first flow at a network device and determining whether flow-identifying information extracted from the first packet matches an existing flow entry. The method also includes, in response to a determination that the flow-identifying information does not match any existing flow entries, generating a new transient flow entry that includes the flow-identifying information and packet-in state. The method also includes forwarding the first packet to a controller via a packet-in stream.

Abstract: A system for forwarding data in a computing environment captures a flow pattern created for a datapath for a data packet. A flow index table is created based on creation of the datapath. Consecutive data packets are forwarded based on matching of forwarding information of subsequent data packets with one or more flow entries in a table index in the flow index table. If there is no flow index table, then the subsequent data packets are forwarded by following one or more flow tables (lookup tables).
