             Transmission of IPv6 Packets over PLC Networks
                         draft-ietf-6lo-plc-04

Abstract

   Power Line Communication (PLC), namely using the electric-power lines
   for indoor and outdoor communications, has been widely applied to
   support Advanced Metering Infrastructure (AMI), especially smart
   meters for electricity.  The inherent advantage of existing
   electricity infrastructure facilitates the expansion of PLC
   deployments, and moreover, a wide variety of accessible devices
   raises the potential demand of IPv6 for future applications.  This
   document describes how IPv6 packets are transported over constrained
   PLC networks, such as ITU-T G.9903, IEEE 1901.1 and IEEE 1901.2.
