OpenFlow 1.3

In this section:

  1. Overview of OpenFlow 1.3
    An OpenFlow switch maintains one or more flow tables, which are used for packet processing. The switch performs the actions listed in the table entry corresponding to the matched flow.
  2. Group table
    Group table introduces the ability to add support for port group abstraction for multi-pathing. This enables OpenFlow to represent a set of ports as a single entity for forwarding packets.
  3. Enqueue
    The controller is able to set up and configure queues and then map flows to a specific queue. The queue configuration sets the queue ID for a packet and determines the queue to be used for scheduling and forwarding the packet.
  4. Metering
    Per-flow metering measures and controls the rate of packets for each flow entry. Per-flow meters enable OpenFlow to implement simple QoS operations, such as rate-limiting, and can be combined with per-port queues to implement complex QoS frameworks, such as DiffServ.
