      Title: MQTT Version 5.0 Working Draft 15

      Abstract:
      MQTT is a Client Server publish/subscribe messaging transport protocol. It is
      light weight, open, simple, and designed to be easy to implement. These
      characteristics make it ideal for use in many situations, including
      constrained
      environments such as for communication in Machine to Machine (M2M) and
      Internet
      of Things (IoT) contexts where a small code footprint is required and/or
      network
      bandwidth is at a premium.
      The protocol runs over TCP/IP, or over other network protocols that provide
      ordered, lossless, bi-directional connections. Its features include:
      • Use of the publish/subscribe message pattern which provides one-to-many
      message distribution and decoupling of applications.
      • A messaging transport that is agnostic to the content of the payload.
      • Three qualities of service for message delivery:
      • "At most once", where messages are delivered according to the best
      efforts
      of the operating environment. Message loss can occur. This level could be
      used,
      for example, with ambient sensor data where it does not matter if an
      individual
      reading is lost as the next one will be published soon after.
      • "At least once", where messages are assured to arrive but duplicates can
      occur.
      • "Exactly once", where messages are assured to arrive exactly once. This
      level could be used, for example, with billing systems where duplicate or
      lost
      messages could lead to incorrect charges being applied.
      • A small transport overhead and protocol exchanges minimized to reduce
      network traffic.
      A mechanism to notify interested parties when an abnormal disconnection
      occurs.
      Notification list:
      Notes:
      wd15 includes tracked changes. Please can thee be accepted before the CSD is
      released. The editors have requested that the Status section be updated, but
      I
      think that's part of the cover sheet and will get replaced anyway.

      Many thanks

      Richard
