5. how to do reliable
messaging over
unreliable
networks? ”

Dr. Andy Stanford-Clark, IBM

6. Background
“MQTT was actually first designed for
Real Time, Mission Critical,
Command & Control, SCADA systems”
- Arlen Nipper, Cirrus Link Solutions

8. Pub/Sub with topic paths
/container/address/devicetype/unique/status <payload>
/minecraft/world/skull/250,72,211/status IS_ALONE
Wildcards: # entire subtree, + a single level

9. Broker
/container/address/devicetype/unique/status <payload>
/minecraft/world/skull/250,72,211/status IS_ALONE
/container/address/devicetype/unique/incoming <payload>
/arduino/1/incoming SERVOS_MOVE,54,69

10. Can combined with REST to
provide notifications

11. Multiple brokers

12. Standard since October 29th

13. IoT-friendly “Tricks”
• Last will & testament
• Binary payload
• 3 QoS levels
• Retained messages
• 2 byte overhead
• Small footprint
• Low bandwidth

14. Mobile: MQTT vs HTTPS

15. Do one thing
and do it well!
“I position MQTT as "the UNIX utility of
M2M" - deliberately simple, easy to plug
in to other tools, languages, and
techniques”
- Andy Piper, Twitter

16. MQTT is so simple that my
children instantly could follow
the message flow and suggest
changes

18. Usages...

19. MQTT might be in your pocket now

21. “MQTT is used both inside as inter-process
communication and in the cloud
for diagnosis”
- Stefano Costa, Bluewind

23. Credo: “Use it as a protocol.
Provide scaling and security as
you need”
