Clear English-language summary of the specification:
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:
o "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.
o "At least once", where messages are assured to arrive but duplicates can
occur.
o "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.
