RFC 3251:Electricity over IP

6. Electricity Encoding

   The Discrete Voltage Encoding (DVE) scheme has been specified in ITU
   standard G.110/230V [2] to digitize electrical voltages.  In essence,
   an Electricity Source (ES) such as a generator is connected to a DV
   encoder that encodes the voltage and current, and  produces a bit
   stream.  This bit stream can be carried in IP packets to various
   destinations (referred to as LERs - Low-voltage Electricity
   Receptors) on-demand.  At the destination, a DV decoder produces the
   right voltage and current based on the received bit stream.  It is to
   be determined whether the Real-time Transport Protocol (RTP) can be

   used for achieving synchronization and end-to-end control.  We leave
   draft writing opportunities in the RTP area to our friends and
   colleagues.
