                      draft-hong-icnrg-ccnx-nrs-02

Abstract

   This document presents the CCNx extension for Name Resolution Service
   (NRS).  It describes TLV-based CCNx messages for NRS and modification
   of CCNx forwarder where the messages for NRS are working.

1.  Introduction

   In Information Centric Networking (ICN)[RFC7927], the name resolution
   is defined as the first step of ICN routing along with content
   discovery and delivery, which translates a content name to locator(s)
   of providers/sources that can provide the content.  However, the name
   resolution step can be omitted in the hierarchical name based
   routing.

   NDN [NDN] and CCN [CCN] are representative projects of ICN which use
   the hierarchical name based routing.  Nevertheless, in [Afanasyev],
   in order to address the routing scalability problem in NDN's DFZ, a
   distributed mapping system called NDNS was designed, which maintains
   and lookups the mapping information from a name to its globally
   routed prefixes.  Here, NDNS is a kind of Name Resolution Service
   (NRS) in NDN.

   Similarly, CCN also has a challlenge to address the routing
   scalability problem in CCN's DFZ even though CCN uses the
   hierarchical name based routing.  Thus, NRS can be utilized in CCN
   for the scalable name based routing as well as the efficient mobility
   support.

   This document presents the design of NRS-Mapping System (NRS-MS)
   which is a system that provides the name resolution service in CCN
   and its implementation by extending CCNx.  It also describes TLV-
