                    draft-irtf-icnrg-ccnxmessages-07

Abstract

   This document specifies the encoding of CCNx messages in a TLV packet
   format, including the TLV types used by each message element and the
   encoding of each value.  The semantics of CCNx messages follow the
   encoding-independent CCNx Semantics specification.

   This document is a product of the Information Centric Networking
   research group (ICNRG).
