2. Techchat on IP for Industrial Networks
Hannes invited Jari Arkko, Tom Phinney and Pascal Thubert to the meeting to lead a discussion on IP for Industrial Networks. Pascal and Tom presented a series of slides with the following abstract:
Wireless Sensor Networks (WSNs) are gaining market acceptance in
numerous industrial segments because they are both cheaper and
faster to deploy than traditional wired field-buses. Wireless
Sensor Networks can also enable incremental value from a variety of
additional usages by leveraging the entire network to connect the
sensors to a centralized controlling application for supervisory
control or logging.
However, a number of issues are raised when it comes to integrating
a proprietary network operated by Process Control (PC) with tight
response time and availability constraints, into a wider, more
complex Information Technology (IT) network that already supports a
large number of applications with wireless, switched and IP
The presentation included an overview of several wireless industrial SDOs, including the International Society of Automation (ISA) [http://www.isa.org/] and the International Electrotechnical Commission (IEC) [http://www.iec.ch/]. Work in the ISA100.11a Working Group relates to some of the work done in the IETF 6LOWPAN Working Group. To date, the IETF has not had much contact with either the IEC or the ISA; the board will investigate ways to reach out to these organizations.
The presentation concluded that wireless and IPv6 will probably be the first IETF technologies to reach industrial floors, but that more work must be done.
After the presentation, the board discussed using the Internet of Things in Industrial Networks as the plenary topic for IETF 82, and agreed to make a final decision at the board meeting on 21 September 2011.
3. Letter to EC on Emergency Services
The board discussed the proposed letter to the European Commission on Emergency Services. Olaf and Joel suggested that changes be made to the letter in order to clarify the IAB’s intended purpose without asking for an open-ended action item. Olaf, Joel and Spencer will revise the letter based on this discussion.
