Hannes, me, Zack, and a few others have been talking about organizing a 
workshop right before the next IETF on IOT. Thoughts? Good idea/bad 
idea? Sufficient participation can be drummed up?


Internet Scale Machine-to-Machine Networking


Today's Internet is experienced by users as a set of applications,
such as email, instant messaging, and social networks. While these
applications do not require users to be present at the time of service
execution in many cases they are. There are also substantial
differences in performance between the various end devices, but in
general end devices participating in the Internet are considered to be
of higher performance.

As we move forward with the interconnection of all kinds of devices to
the Internet, these characteristics will change. "Internet of Things"
is a vision where a large number of devices benefit from the
communication services offered by the Internet. Many of these devices
are not directly operated by humans, but exist as stand-alone
components in buildings, vehicles, and the environment. There will be
a lot of variation in the computing power, available memory, and
communications bandwidth between different types of devices.

Many of these devices provide new services or provide more value for
our previously unconnected devices. Some devices have been connected
in various legacy means in the past but are now migrating to the use
of the Internet Protocol, sharing the same communications medium
between all applications and enabling rich communications services.

Much of this development can simply run on existing Internet
protocols. For instance, home entertainment and monitoring systems
often offer a web interface to the end user. In many cases the new,
constrained environments can benefit from additional protocols that
help optimize the communications and lower the computational
requirements. Examples of standardization efforts targeted for these
environments include the "Constrained RESTful Environments (core)",
IPv6 over Low power WPAN (6lowpan)", Routing Over Low power and Lossy
networks (roll)" working groups.

This workshop aims to explore the experience and approaches taken by
developers of Internet technology, when considering the
characteristics of constraint devices. Engineers know that many design
considerations need to be taken into account when developing protocols
and architecture. Balancing between the conflicting goals of computing
performance, code size, economical incentives, and security is often
difficult, as illustrated by Clark, et al. in "Tussle in Cyberspace:
Defining Tomorrow's Internet", see

This workshop aims to discuss the experience and approaches taken when
designing Internet of Things into protocols and architectures. To
frame the discussion we suggest, as examples, to investigate the area
of integration in the following categories:

* scalability
* power usage
* interworking between different technologies and network domains
* usability and manageability
* security

"To make the Internet work better" is the goal of the IETF and the
workshop organizers are interested in receiving contributions and in
having discussions that support this goal. Results may lead to
guidelines and recommendations, the development of standards, further
need for research, or implementation and configuration best current

Workshop Style

The workshop’s main focus will be on the discussions. In order to keep
the group at a manageable size, participants are required to submit a
position paper as an expression of interest. Submitters of accepted
position papers will be invited to attend the workshop. Active
participation will be expected.

The workshop will be structured as a series of working sessions
punctuated by invited speakers who will present relevant background
information or controversial ideas that help participants reach a
deeper understanding of the subject. The organizing committee may ask
submitters of particularly salient papers to present their ideas and
experiences at the workshop. For each slot, there will be one or two
invited controversial speakers, and group work on the problem that’s
identified, hopefully reaching either a deeper understanding of the
problem or some means of approaching it.

Important Dates

Position papers must be submitted at latest February, 11th, 2011.

Submitted position papers will be reviewed immediately by the program
organizers and an invitation to the workshop will be sent to one of
the paper authors. At latest, invitations will be distributed by
February, 25th.

This one-day workshop will take place on Friday, 25th March, 2011,
right before the 80th IETF meeting in Prague, which starts on Sunday,
27th March. Independently of this workshop but relevant for the
participants are tutorial events on Saturday, 26th March 2011. These
tutorials will focus on ongoing IETF efforts related to the IETF CORE,
ROLL, and 6LOWPAN working groups.

Position Papers Requirements

Interested parties must submit a brief contribution describing their
work or approach as it relates to the workshop theme. We welcome
visionary ideas for how to tackle the integration of constraint
devices, as well as write-ups of deployment experience, and
lessons-learned from successful or failed attempts at integrating
these constraint devices with the Internet. Contributions are not
required to be original in content.

We solicit brief write-ups with 1 or 2 pages, formatted in HTML, PDF,
or plain text. We encourage paper authors to focus on the most
important challenge. A focused message will be key! Accepted position
papers will be published (in addition to meeting minutes, slides, and
a workshop report).

Please send your position paper to iot-workshop-prep@lists.i1b.org.


The planned date and location for the workshop is Friday, March 25th,
in Prague. Details about the meeting venue will be provided to the
invited workshop participants. During the breaks coffee and tea will
be served.

There are no plans for remote participation. Minutes of discussions
will be available, and offers to organize audio recording would be
gladly appreciated.

Workshop Organizers

We look forward to your input. The workshop organizers are Jari Arkko
(Internet Area Director), Hannes Tschofenig (IAB), Bernard Aboba
(IAB), Carsten Bormann (core and 6lowpan WG Chair), David Culler (ROLL
WG Chair), Lars Eggert (Transport Area Director, and upcoming IRTF
Chair), JP Vasseur (ROLL WG Chair), Stewart Bryant (Routing Area
Director), Adrian Farrel (Routing Area Director), Ralph Droms
