Internet Engineering Task Force (IETF) F. Baker Request for Comments: 6272 D. Meyer Category: Informational Cisco Systems ISSN: 2070-1721 June 2011 Internet Protocols for the Smart Grid Abstract This note identifies the key infrastructure protocols of the Internet Protocol Suite for use in the Smart Grid. The target audience is those people seeking guidance on how to construct an appropriate Internet Protocol Suite profile for the Smart Grid. In practice, such a profile would consist of selecting what is needed for Smart Grid deployment from the picture presented here.
