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.
