Abstract

   Content distribution applications, such as those those employing
   peer-to-peer (P2P) technologies, are widely used on the Internet and
   make up a large portion of the traffic in many networks.  Often,
   however, content distribution applications use network resources in a
   counter-productive manner.  One way to improve efficiency is to
   introduce storage capabilities within the network and enable
   cooperation between end-host and in-network content distribution
   mechanisms.  This is the capability provided by a DECADE system,
   which is introduced in this document.  DECADE enables applications to
   take advantage of in-network storage when distributing data objects
   as opposed to using solely end-to-end resources.  This document
   presents the underlying principles and key functionalities of such a
   system and illustrates operation through a set of examples.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at http://datatracker.ietf.org/drafts/current/.

   Internet-Drafts are draft documents valid for a maximum of six months
   and may be updated, replaced, or obsoleted by other documents at any
   time.  It is inappropriate to use Internet-Drafts as reference
   material or to cite them other than as "work in progress."
