  24 === Message Order Preservation
  25
  26 While the Helium release of OpenFlow Plugin relied on queues to ensure messages were delivered in order, subsequent releases instead ensure that all the messages from a given device are delivered using the same thread and thus message order is guaranteed without queues. The OpenFlow plugin allocates a number of threads equal to twice the number of processor cores on machine it is run, e.g., 8 threads if the machine has 4 cores.
  27
  28 NOTE:
  29 While each device is assigned to one thread, multiple devices can be assigned to the same thread.
