         ANSI C12.22, IEEE 1703, and MC12.22 Transport Over IP

Abstract

   This RFC provides a framework for transporting ANSI C12.22/IEEE
   1703/MC12.22 Advanced Metering Infrastructure (AMI) Application Layer
   Messages on an IP network.

   This document is not an official submission on behalf of the ANSI
   C12.19 and C12.22 working groups.  It was created by participants in
   those groups, building on knowledge of several proprietary C12.22-
   over-IP implementations.  The content of this document is an
   expression of a consensus aggregation of those implementations.
