The Interknot -
or
The Unintended Consequences of Internetworking Different
Kinds of Networks

The Internet of Things is a buzz phrase we see quite a lot recently.
In this catchy vision, it is imagined that we connect objects in the
real world (sensors, actuators) to the Internet in the same way that
we have connected input/output devices that humans use to the vast
Information System that is the Web and the Cloud.

Objects such as temperature and air sensors, home appliances, cars,
and entire existing other types of networks such as rail and air
transport systems, and power grids, are all seamlessly interconnected
in an harmonious firmament. At least that is the vision.

However, each of these networks (domestic appliances, factory
production lines, power, transportation) has its own disciplines.
Each has developed a set of methods to build stable, safe, affordable
controls, crucially, in isolation from other systems.

The Internet has its own culture and discipline, but it is somewhat
more open than the communities of scientists, engineers and
operators in those other networks (many utilities) are accustomed to.
Opening up the other networks by Internet-enabling them, is very
promising. It is also fraught with incredible risks.

In this talk, I will discuss 2 or 3 examples of cutural, technical,
and operational risks associated with connecting individial cars as
well as transportation systems and power grids, to and via the
Internet. I will also point out that these risks can be averted with
appropriate mutual education between the communities that work on
these very different networks.
