           TinyIPFIX for smart meters in constrained networks
                      draft-schmitt-ipfix-tiny-02

Abstract

   This document specifies the TinyIPFIX protocol that serves for
   transmitting smart metering data in constrained networks such as
   6LoWPAN [RFC4944].  TinyIPFIX is derived from IPFIX [RFC7011] and
   adopted to the needs of constrained networks.  This document
   specifies how the TinyIPFIX Data and Template Records are transmitted
   in constrained networks such as 6LoWPAN and how TinyIPFIX data can be
   converted into unTinyIPFIX data in a proxy device.
