   Architectural Considerations of ICN using Name Resolution Service
               draft-irtf-icnrg-nrsarch-considerations-01

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 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
   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
   [NRSrequirements].
