Re: The IETF and the SmartGrid

Thanks. You already know this, as does Russ Housley, but I'll say it out loud for others to hear.

At the third NIST workshop on the Smart Grid, which was the week following the IETF meeting, several IETFers were invited by David Su of NIST to a workshop on the role of the Internet Architecture in the Smart Grid. He specifically asked for a document that could be used to discuss and describe the Internet Architecture, specifically to support the "profiling" (eg, subseting) of its architecture for the purpose. To that end, I started

http://tools.ietf.org/html/draft-baker-ietf-core
"Core Protocols in the Internet Protocol Suite", Fred Baker, 3- Oct-09,
  <draft-baker-ietf-core-03.txt>

The initial document essentially described the protocols appropriate to a host; at the request and behest of several commentators, I have since added a brief description of unicast and multicast routing, QoS, address allocation and assignment (DHCP and ND), NTP, DNSSEC, SIP, the ISO Transport Service Interfaces (necessary for ACSE, which is used in the Smart Grid) and something of the business architecture of the Internet and therefore firewalls, NATs, and VPNs. I have in the can a version that puts in references for MPLS, and given that NIST is asking about calendaring and SNMP will likely include a few sentences on those.

I'm trying to walk what is at best a grey line; The things that are at the Internet Architecture's absolute core, at least to my mind, are described in RFCs 1122, 1123, and 1812. However, NIST is asking about the place of more things (like calendaring and timekeeping) and other possible users of the document are also asking for things that are more core to the business than the architecture, like NATs and MPLS. So I am trying to describe things that are core, and also answer useful questions about less-core things, all without trying to provide a list of all 1574 proposed standards, 89 draft standards, and 82 standards.

Individuals who have noticed the draft have commented; folks who care should also do so. I have asked the IESG for directorate reviews, but have not gotten anything from any directorates.

As you say, NIST is requesting commentary on http://www.nist.gov/public_affairs/releases/smartgrid_interoperability.pdf . Those of us that work for US corporations or educational institutions would likely be wise to be involved in corporate reviews and replies, as that is how most review of this type comes back. The exact structure to reply in has not yet been announced, but I would imagine that will be remedied soon.

The general internet community needs to be aware of activities in North America that directly relate to the use of IETF protocols in the Electric Utility industry. This activity is generally referred to as the SmartGrid. Though the issues immediately deal with technical and policy decisions in the US and Canada, the SmartGrid concept is gaining significant momentum in
Europe and Asia as well.

The SmartGrid has many definitions but as a practical matter it is a
substantial re-architecture of the data communications networks that
utilities use to maintain the stability and reliability of their power
grids. Many of the requirements for the SmartGrid in North America came out of the 2003 North East power outage which demonstrated a substantial lack of
investment in Utility IT systems.

http://www.ferc.gov/EventCalendar/Files/20040915141105-blackout.pdf

Of particular note, is the desire by utilities to extend the reach of their communications networks directly to the utility meter and beyond ultimately
into the customer premise itself. This is generally referred to as the
Advanced Meter Interface (AMI).  One of the use cases driving this
requirement is the next generation of plug-in hybrid electric vehicles. The utilities, correctly IMHO, want to precisely control the timing of how these vehicles are recharged so not to create a unique form of DOS attack and take out the grid when everyone goes home at night. This is a principal use case
in 6lowpan ( ID below ). Increasingly energy flows are becoming
bi-directional creating needs for more computational intelligence and
capability at the edge.

What is going on? Why should the IETF community care?

The United States Government, as part of the Energy Independence and
Security Act of 2007 gave the National Institute of Standards and Technology ( NIST ) principal responsibility "to coordinate development of a framework
that includes protocols and model standards" for the SmartGrid.

http://www.nist.gov/smartgrid/


After several meetings sponsored by NIST in recent months, NIST released a preliminary report. Several folks from the IETF community attended those meetings, myself included. There multiple troubling stories about how those
meetings were organized but I'll leave those tales to others.

http://www.nist.gov/public_affairs/releases/smartgrid_interoperability.pdf

One of the requests from NIST and the SmartGrid community was a list of Core Internet protocols that NIST could refer to. Fred Baker has been working on
that task. ( below )

Myself and others are deeply concerned by how this effort is developing. There is no current consensus on what the communications architecture of the
SmartGrid is or how IP actually fits into it.

The Utility Industry does not understand the current IPv4 number exhaust problem and the consequences of that if they want to put a IP address on
every Utility Meter in North America.

What is equally troubling is that many of the underlying protocols that utilities wish to deploy are not engineered for IPv6. We have an example of
that in a recent ID.

http://tools.ietf.org/html/draft-c1222-transport-over-ip-01.txt


Obviously, there are significant CyberSecurity issues in the SmartGrid
concept and NIST has produced a useful document outlining the requirements
and usecases.

http://csrc.nist.gov/publications/drafts/nistir-7628/draft-nistir-7628.pdf

How the SmartGrid interfaces with or bridges with Home Area or Enterprise
Local Area networks is unclear, to put it mildly.

I want to use this message to encourage the community to read the attached documents and get involved in this effort as appropriate. Additional NIST
documents will be published shortly with a open public comment period.

I strongly urge members of the IETF community to participate in this comment
period and lend its expertise as necessary.

It's useful and important work.

This note attempts to identify the core of the Internet Protocol Suite. The
target audience is NIST, in the Smart Grid discussion, as they have
requested guidance on how to profile the Internet Protocol Suite.  In
general, that would mean selecting what they need from the picture presented
here.

This document investigates potential application scenarios and use cases for low-power wireless personal area networks (LoWPANs). This document provides
dimensions of design space for LoWPAN applications.
A list of use cases and market domains that may benefit and motivate the work currently done in the 6LoWPAN WG is provided with the characterisitcis of each dimention. A complete list of practical use cases is not the goal
of this document.
