11. However…
The market is fragmented
– Hardware, software, protocols…
all different, independent
– Lack of integration…
between devices, to enterprise systems
M2M development is complex
– Many different skills required…
Hardware, Embedded, IT network, Telecom, web
– No common architectural guidelines
Current options are closed
– Monolithic solutions…
device specific, app specific, market specific
– Proprietary SDKs, protocols, potential vendor lock-in

17. MQTT in a Nutshell
■ MQTT == MQ Telemetry Transport
■ In a nutshell
“A light weight event and message oriented
protocol allowing devices to asynchronously
communicate efficiently across constrained
networks to remote systems”
18. MQTT - Publish Subscribe Messaging
A Publish Subscribe messaging protocol allowing a message to be published once and multiple consumers
(applications / devices) to receive the message providing decoupling between the producer and consumer(s)
A producer sends (publishes) a message (publication) on a topic (subject)
A consumer subscribes (makes a subscription) for messages on a topic (subject)
A message server / broker matches publications to subscriptions
• If no matches the message is discarded
• If one or more matches the message is delivered to each matching subscriber/consumer
19. Benefits of MQTT verses HTTP
■ Push delivery of messages / data / events
– MQTT – low latency push delivery of messages from client to server and server to client
• Helps bring an event oriented architecture to the web
– HTTP – push from client to server but poll from server to client
• Efficient use of network
– For an M2M project the number of bytes with MQTT was 137130 bytes per device per month with
HTTP the number of bytes was 801000 bytes per device per month
• Reliable delivery over fragile network
– MQTT will deliver message to QOS even across connection breaks
• Decoupling and publish subscribe – one to many delivery

20. M3DA Layered Architecture
Application Layer – M3DA::Message
– Specify access to the tree-oriented data
model
Transport Layer – M3DA::Envelope
– Enables authentication, encryption,
compression, …
Serialization Layer – Bysant
– Provides an efficient binary serialization
based on contextual information

– Now an OASIS TC
– operates under the Non-Assertion Mode of the
OASIS IPR Policy
• M3DA
– Specification and implementation are made
available under the Eclipse Public License
– Royalty-free patent license
