17. A-MQ : Highly Tunable
• AMQ.XML  we have tuned about 60
parameters

18. Why MQTT
• M2M Messaging Protocol
• Low Bandwidth / Low Power
• 2-way Communication
• Publish and Subscribe
• Hierarchical Topic Namespaces
• Data Payload Agnostic
• Device Initiated Connection
• Firewall-friendly
• SSL and Authenticated
• Large ecosystem

19. Benefits of MQTT versus HTTP
Source: http://stephendnicholas.com/archives/1217
• Push delivery of messages /
data / events
• MQTT – low latency 2-way
communication
• HTTP – push from client but
poll from server
• Efficient use of network
• Reliable delivery over fragile
network
• Decoupling publishers and
subscribers – one to many
delivery

20. MQTT is OK …
but NOT ENOUGH

21. What’s beyond MQTT ?
At the Device Side (client)…
• Transport Service
–Transport Service Abstraction
–Credentials & Authentication management
–Provisioning
6

22. What’s beyond MQTT ?
At the Device Side (client)…
• Data Services
– Manages remote connectivity and reconnect
policies
– Manages message queuing with priority
– Manages message store while disconnected and
resume publishing on reconnects
5

23. What’s beyond MQTT ?
At the Device Side (client)…
• Cloud Services
– Data model for telemetry applications
– Topic partitioning across applications
– Compression
– Birth, Death & App certificates
– Request and Response message exchanges
– Simplified code for remote resource management
4

24. What’s beyond MQTT ?
At the Broker (server)…
• Broker Plugin
– Enforces Authentication
– Enforces Authorization Topic ACLs
– Enforces Account Policies
– Tracks User Logins
3

25. What’s beyond MQTT ?
At the Broker (server)…
• Device Connectivity
– Tracks Device Connectivity
– Update Device Status
• Data Store
– Store messages on IoT noSQL BigData DB
2

26. What’s beyond MQTT ?
At the Broker (server)…
• Rules Engine Bundle
– Inspect messages, check rules and trigger
actions
• A-MQ Cluster Support & Protocol translation
• Custom Bundles
1

27. A-MQ IoT Challenges
• A-MQ instances exposed on the
Internet for device direct connectivity
• Scale on number of connections not just
number of messages
ESB scenario IoT scenario

28. Recommendations
• Protect the broker instances
– Firewall configuration, secure A-MQ connectors,
SSL enforcements (i.e. <sslContext>),
– Configure broker cluster for reliability for the
creation of a network of brokers
6

29. Recommendations
• Consider SSL Termination
– Keep it off-broker, as a different SSL-proxy node
decoding SSL-2-noSSL
5

30. Recommendations
• OSGi is your friend, respect its architecture !
– Deploy Consumers closer to the Broker (no
messages over TCP)
– Use “vm” connector (direct mem links)
4

31. Recommendations
• Apply General A-MQ Tunings to
configure a Network of Brokers
https://access.redhat.com/documentation/en-
US/Red_Hat_JBoss_A-
MQ/6.0/html/Tuning_Guide/files/PersTuning-
Horizontal.html

32. Recommendations
• Set persistence engine tuning
for high-speed message
storage & retrieval
https://access.redhat.com/documentation/en-
US/Red_Hat_JBoss_A-
MQ/6.0/html/Tuning_Guide/files/PersTuning-
KahaDB.html
2

33. Recommendations
• MQTT Tuning
– Nio (decoupling java threads from connections)
– Disable JMX due to large number of Topics;
Monitor using advisory messages
(advisorySupport=TRUE in AMQ.XML)
– Increase Durable Topic Prefetch for bulk msg
batch processing (activeMQSubscriptionPrefetch)
1

34. Recommendations
• From ActiveMQ 5.11, try virtual-topic-subscriptions
– Set a pool of subscribers
– Send a message in round-robin to just one of them rather
then towards them all (as by default publish-subscribe)

36. Application:
Monitor & analyze people flows and correlate with
environmental monitoring data and with Social Media like
Twitter at the RedHat Summit & DevNation 2015 event in Boston.
Key Success Factors:
PCN features & technology (e.g. stereoscopic vision)
Complete set of M2M/ IoT building blocks available
Java centric development of device application
Effective integration with APPS and dashboards via REST API
Complete IoT end-to-end solution with other Red Hat Partners
Short development time
Product:ReliaGATE 10-20 with
PCN-10-01 &
ReliaSENS 18-12
Smart Events: People Flow + Air Qualty
+ Social Media

37. Application:
Optimize and improve the sanitary services in public buildings.
The system is used to monitor restrooms attendance in order to
activate the staff according to the precise needs (number of
visitors) rather than on a time schedule
Key Success Factors:
PCN features & technology (e.g. stereoscopic vision)
Complete set of building blocks offered
Complete end-to-end solution
Short development time
performance, flexibility and simplicity of data treatment
(storage, download, accessibility, analysis)
Product:
Helios with
PCN-1000
Passenger Counter
The Sanitary Service Optimization

38. Taxi Queue Optimization
Application:
The goal was to improve the customer service and the
optimization of taxi routing to increase revenues and
reduce waiting times, and, finally, to increase the driver’s
security.
Key Success Factors:
Short time to market due to easy EDC approach
ESF for natively connecting PCN to Cloud
Smart Cameras connected to Cloud
Increased Drivers Security (alarm button with GPS
positioning and Taxi ID)
Increased Customer Satisfaction
Increased Taxi Revenues
Product:
ReliGATE 50-21 with
PCN-1000
Passenger Counter

39. Application:
The customer required a programmable Intel cellular platform for
monitoring of refrigeration units at grocery stores for energy
and asset management application.
Key Success Factors:
flexibility of ESF
Started with Helios… software portability across HW
Eurotech M2M knowledge and experience
Flexible hardware platform
long term data-metrics storage
