                   draft-xli-softwire-map-testing-09

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
   [RFC7599] [RFC7597].  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
