    An architectural framework of the internet for the real IP world
                  draft-shyam-real-ip-framework-15.txt

Abstract

   This document tries to propose an architectural framework of the
   internet in the real IP world. It shows how to reorganize the
   provider network with a large address space. It describes how a
   three-tier mesh structured hierarchy can be established based on
   fragmenting the entire space 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.

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
   16-bit to support the demand at the same time [4]. The challenge
   relies on how to make the transition smooth from IPv4 to a real IP
   world with least changes possible.

2. Background

   Existing system is in work with Autonomous System (AS) and inter-AS
   layer with the approach of CIDR. In order to meet the need within the
   32-bit address space, Autonomous Systems of various sizes maintain
   CIDR based hierarchical architecture. With the help of NAT [5], a
   stub network can maintain an user ID space as large as a class A
   network and can meet its useful need to communicate with the rest of
   the world with very few real IP addresses. With the combination of
   CIDR and NAT applied in the entire space, most of the part of 32-bit
