                         Address Mapping System
                      draft-herbert-intarea-ams-00

Abstract

   This document describes the Address Mapping System that is a generic,
   extensible, and scalable system for mapping network addresses to
   other network addresses. The Address Mapping System is intended to be
   used in conjunction with overlay techniques which facilitate
   transmission of packets across overlay networks. Information returned
   by the Address Mapping System can include the particular network
   overlay method and instructions related to the method.  The Address
   Mapping System has a number of potential use cases networking
   including identifier-locator protocols, network virtualization, and
   promotion of privacy.
