    An Architectural Framework of the Internet for the Real IP World
                  draft-shyam-real-ip-framework-42.txt

Abstract

   This document tries to propose an architectural framework of the
   internet in the real IP world. It describes how a three-tier mesh
   structured hierarchy can be established in a large address space
   based on fragmenting it into some regions and some sub regions inside
   each of them. It addresses issues which could be relevant to this
   architecture in the context of IPv6. It shows how to make a
   transition from private IP to real IP without making significant
   changes with the existing network.

1. Introduction

   Transition from IPv4 to IPv6 is in the process. Work has been done to
   upgrade individual nodes (workstations) from IPv4 to IPv6. Also,
   there are established documents to make routers/switches to work to
   support IPv4 as well as IPv6 packets simultaneously in order to make
   the transition possible [1].  CIDR[2] based hierarchical architecture
   in the existing 32-bit system is supposed to be continued in IPv6 too
   with a large address space. There are documents/concerns over BGP
   table entries to become too large in the existing system [3]. There
   are proposals to upgrade Autonomous System number to 32-bit from
