Abstract

   This document describes a SOCKS-based IPv6/IPv4 gateway mechanism
   that enables smooth heterogeneous communications between the IPv6
   nodes and IPv4 nodes.

   It is based on the SOCKS protocol [SOCKSv5].  By applying the SOCKS
   mechanism to the heterogeneous communications and relaying two
   "terminated" IPv4 and IPv6 connections at the "application layer"
   (the SOCKS server), the SOCKS-based IPv6/IPv4 gateway mechanism is
   accomplished.

   Since it is accomplished without introducing new protocols, it
   provides the same communication environment that is provided by the
   SOCKS mechanism.  The same appearance is provided to the
   heterogeneous communications.  No conveniences or functionalities of
   current communications are sacrificed.

1. Introduction

   The SOCKS-based IPv6/IPv4 gateway mechanism is based on a mechanism
   that relays two "terminated" IPv4 and IPv6 connections at the
   "application layer" (the SOCKS server); its characteristics are
   inherited from those of the connection relay mechanism at the
   application layer and those of the native SOCKS mechanism.
