           TinyIPFIX for smart meters in constrained networks
                      draft-schmitt-ipfix-tiny-01

Abstract

   This document specifies the TinyIPFIX protocol that serves for
   transmitting smart metering data in 6LoWPAN networks [RFC4944].
   TinyIPFIX is derived from IPFIX [RFC7101] and adopted to the needs of
   constrained networks.  This documents specifies how the TinyIPFIX
   Data and Template Records are transmitted in 6LoWPAN networks and how
   TinyIPFIX data can be converted into unTinyIPFIX data in a proxy
   device.
