   Architectural Considerations of ICN using Name Resolution Service
               draft-irtf-icnrg-nrsarch-considerations-00

Abstract

   This document discusses architectural considerations and implications
   of Information-Centric Networking (ICN) related to the usage of the
   Name Resolution Service (NRS).  It describes how ICN architecture
   changes and what implications are in the routing system when NRS is
   utilized in ICN.

1.  Introduction

   Information-Centric Networking (ICN) is an approach to evolve the
   Internet infrastructure to directly access Named Data Objects (NDOs)
   by its name, i.e., the name of NDO is directly used to route the
   request to the data object.  Such name based routing in ICN poses a
   number of issues, which are not solved yet in ICN.  These issues
   includes global scalability of routing, producer mobility, off-path
   cache, etc.  In order to address these issues, the name resolution
   function has been applied to several ICN projects and literature
   [Afanasyev][Zhang2][Ravindran][MF][Bayhan].

   Thus, this document describes how ICN architecture changes and what
   implications are in the routing system when Name Resolution Sevice
   (NRS) is utilized in ICN.  It also discusses ICN architectural
   considerations for a NRS.
