“...the Paho project has been created to provide scalable open-source implementations of open

and standard messaging protocols aimed at new, exisiting, and emerging applications for Machine-

to-Machine (M2M) and Internet of Things (IoT)”

•MQTT has been a published protocol for a number of years to assist & ease of adoption by device vendors and third-parties - http://mqtt.org/

• In August 2011, Eurotech and IBM announced their intention to take the MQTT specification to a formal standards organisation – seehttp://mqtt.org/2011/08/open-invitation-to-join-the-mqtt-standardization-discussion

•On November 2nd at EclipseCon the following was announced:• The formation of a new M2M Industry Working Group at the Eclipse Foundation,

with Sierra Wireless, Eurotech and IBM as founding members, to work on growing and scaling device connectivity solutions with open source tools, frameworks and runtimes.

• The contribution of the IBM MQTT client code (C and Java) to a new Eclipse project "Paho".

•MQTT has potential as a major enabling technology for the future of machine to machine (M2M), business to consumer (B2C) and business to employee (B2E) interaction.

Eclipse Paho: ProposalThe scope of the Paho project is to provide open source implementations of open and standard messaging protocols that support current and emerging requirements of M2M integration with Web and Enterprise middleware and applications. It will include client implementations for use on embedded platforms along with corresponding server support as determined by the community.

In order for M2M device and client developers to integrate, develop and test messaging components end-to-end, Paho will address the development of frameworks and sample code needed to support testing and development of end-to-end device connectivity with a server. The project will make these available in an Eclipse M2M sever “sandbox”, as recommended by the Eclipse M2M Industry Working Group.

The Paho project scope includes the development of tooling that will support effective use, integration and testing of the messaging components.

Progress report!

• M2M “sandbox” instance of mosquitto broker available:• m2m.eclipse.org:1883• currently, no multi-tenancy, security etc

• Initial source code contributions from IBM on Eclipse Git:• C client

http://git.eclipse.org/c/paho/org.eclipse.paho.mqtt.c.git/• Java client

http://git.eclipse.org/c/paho/org.eclipse.paho.mqtt.java.git/

•Project mailing list and wiki available:•paho-dev•http://wiki.eclipse.org/Paho

•End-to-end demos at EclipseCon 2012: Koneki LDT, Eurotech etc.

Getting involved

• Paho Bugzilla becoming active ☺→ bugs.eclipse.org

• Most activity still via mqtt.org community; aim to drive more interaction via paho-dev mailing list• where relevant to Paho topics!• specification discussion via the MQTT Google Group

• Write-up use cases, build guides, experiences etc

• Hashtag Twitter discussions → #mqtt #paho (and @mqttorg)

Next Steps?• Eurotech Eclipse plugin contribution

• Cross-platform builds → downloads available as binary “quickstarts”

• Build guides and tutorials (EclipseCorner?)

• Advocate to wider Eclipse community (beyond Koneki / Lua)NB “when’s the coming out party?”• e.g. Android mobile dev, OSGi framework, etc.

• Identify additional requirements:• Java/OSGi-based MQTT server (e.g. Ford/openxcPlatform, Hitachi/

home devices, etc)• bring additional language bindings into Paho (Lua, others?)

• M2M Developer Portal

• More M2M-IWG participation, and progress to standards body
