Paho set for late November release

IBM and Eurotech propose Paho – an Eclipse open source device connectivity project

Paho-Proposal-2

Landmark partnership could usher in new era of interconnectivity

With Eclipse’s 10th anniversary at EclipseCon in Germany, it
seemed the perfect time announce something revolutionary as IBM and
Eurotech revealed their contribution to the Eclipse foundation –
hoping to utilise the open source community in driving forth the
push for advanced machine to machine technology (M2M).

According to a recent Ericsson survey, by 2020, there will be
over 50 billion connected devices in the world. Combined with a
projected 1000% increase in wireless broadband traffic by then, it
is of paramount performance that technology continues to grow to
meet that demand and the advances in embedded programmes.

The Paho
project
 aims to eliminate the middle man between the
connection of physical systems and smart devices, providing a more
cohesive system of interconnectivity and also the possibility of
‘an internet of things’. M2M is already key to much of the world’s
functions, but over constrained wireless connections and this step
could theoretically create new messaging opportunities, integrating
Web and Enterprise middleware much more seamlessly with physical
objects

IBM bring the MQTT technology for the project –
a lightweight publish/subscribe protocol designed for mobile
and remote devices, wireless connectivity, and dealing with lossy,
constrained and/or intermittent network characteristics. Eurotech
will provide the framework and sample applications for testing,
meaning that Eclipse will set up a functioning test sandbox server.
IBM’s Scot de Deugd will lead the project.

The documents submitted to Eclipse outline a scenario of a burst
water main. Sensors already present in the system notify operators
of the issue who in turn report the status of flooding in streets
and subways. But this is a fairly strict and linear way of doing
things. Through well designed open messaging technology, further
opportunities could allow public and private transit systems to
monitor the alerts, to change their routes if needs be, or social
networks could subscribe to notify residents in the area and allow
them to give feedback.

The proposal outlines the needs for
progression.

Open source messaging components are
needed that can cater to the serendipitous nature of data and
events from the physical world around us, accelerating and opening
new markets. These components will of course have to support the
open messaging models prevalent on the Web. They will have to meet
high volume, low latency transaction requirements expected by
Enterprise IT.  At the same time, they will have to work
equally well across the constrained networks and embedded platforms
that are inherent to physical world of machine-to-machine
systems. 

This will enable a paradigm shift from
legacy point-to-point protocols and the limitations of protocols
like SOAP or HTTP into more loosely coupled yet determinable
models. It will bridge the SOA, REST, Pub/Sub and other middleware
architectures already well understood by Web 2.0 and Enterprise IT
shops today, with the embedded and wireless device architectures
inherent to M2M.

IBM and Eclipse have enjoyed a healthy relationship over the
past decade, with the Eclipse community contributing hugely towards
IBM products. And given that bond, you’d be foolish to bet against
this venture flourishing too. The Paho proposal outlines why
Eclipse were chosen for the open source project.

The Eclipse Foundation has initiated
an M2M Industry Working Group, recognizing the importance of
growing and scaling device connectivity solutions needed to realize
new business opportunities and keep markets open. Eclipse has a
large and diverse membership, an established industry presence, and
a proven track record on technology projects.  The industry
working group will provide a forum for discussing the broad topics
of machine-to-machine communications while the Paho open source
project will make implementations of advanced messaging technology
readily available to M2M, Web and Enterprise customers, working to
improve adoption. 

Paho will be intrinisically linked to
Equinox and other Eclipse projects such as Konecki and other web,
enterprise and embedded tooling projects within the community.

The initial release of the MQTT Java
and C Client code is scheduled for the 28th November 2011 with the
Stable 1 release expected by December 16.
