                   draft-xli-softwire-map-testing-05

Abstract

   This document presents the testing results of a unified code
   accommodating encapsulation and translation modes of Mapping of
   Address and Port (MAP).  Experiments show that the unified MAP CE is
   not only supporting MAP-E and MAP-T modes, but also backward
   compatible with AFTR of dual-stack lite and stateless/stateful NAT64.

1.  Introduction

   Generic mechanism for mapping between an IPv4 prefix, address or
   parts of thereof, and transport layer ports and an IPv6 prefix or
   address with translation mode and encapsulation mode are specified in
   [I-D.ietf-softwire-map-t] [I-D.ietf-softwire-map].  This document
   presents testing results of a unified code containing translation and
   encapsulation modes of Mapping of Address and Port (MAP).  The
   backward compatibility of MAP CE with AFTR of dual-stack lite and
   NAT64 of stateful translation are also presented.

1.1.  Testing Topology

   The testing topology is shown in the following figure.
