   Architectural Considerations of ICN using Name Resolution Service
               draft-irtf-icnrg-nrsarch-considerations-02

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 architectures
   may change and what implications are introduced within the ICN
   routing system when NRS is integrated into 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 has
   inherent challenges in supporting globally scalable routing system,
   producer mobility, off-path caching, etc.  In order to address these
   challenges, the Name Resolution Service (NRS) has been integrated
   into several ICN projects and literature
   [Afanasyev][Zhang2][Ravindran][SAIL][MF][Bayhan].

   This document describes how ICN architectures may change and what
   implications are introduces within the ICN routing system when NRS is
   integrated into ICN.  It also discusses ICN architectural
   considerations for an NRS.  In other words, the scope of this
   document includes considerations in the veiw of the ICN architecture
   and routing system when integrating NRS into ICN.  However, it does
   not include the NRS discussion, itself, which is presented in
   [NRSguidelines].
