Abstract

   This memo describes research challenges for Information-Centric
   Networking.  Information-Centric Networking is an approach to evolve
   the Internet infrastructure to directly support information
   distribution by introducing uniquely named data as a core Internet
   principle.  Data becomes independent from location, application,
   storage, and means of transportation, enabling in-network caching and
   replication.  Challenges include naming, security, routing, system
   scalability, mobility management, wireless networking, transport
   services, in-network caching, and network management.

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."
