Abstract

   This document describes the core concepts of the CCNx architecture
   and presents a minimum network protocol based on two messages:
   Interest and Content Object.  It specifies the set of mandatory and
   optional fields within those messages and describes their behavior
   and interpretation.  This architecture and protocol specification is
   independent of a specific wire encoding.

   The protocol also uses a Control message called an InterestReturn,
   whereby one system can return an Interest message to the previous hop
   due to an error condition.  It indicates to the previous hop that the
   current system will not respond to the Interest.
