1.  Abstract

   This document describes how proxy chaining and policy implementation
   can be supported in roaming systems. The mechanisms described in this
   document are in current use.

   However, as noted in the security considerations section, the
   techniques outlined in this document are vulnerable to attack from
   external parties as well as susceptible to fraud perpetrated by the
   roaming partners themselves. As a result, such methods are not
   suitable for wide-scale deployment on the Internet.

2.  Terminology

   This document frequently uses the following terms:

   Network Access Server
      The Network Access Server (NAS) is the device that clients contact
      in order to get access to the network.

   RADIUS server
      This is a server which provides for authentication/authorization
      via the protocol described in [3], and for accounting as described
      in [4].
