1. Introduction

1.1 Overview

   This document defines an architecture framework for transport of
   message-based signaling protocols over IP networks.  The scope of
   this work includes definition of encapsulation methods, end-to-end
   protocol mechanisms and use of existing IP capabilities to support
   the functional and performance requirements for signaling transport.

   The framework portion describes the relationships between functional
   and physical entities used in signaling transport, including the
   framework for control of Media Gateways, and other scenarios where
   signaling transport may be required.
