1.  Introduction

   There are numerous mechanisms being proposed to solve the problem of
   securely introducing a new devices into an existing managed network.

   This document provides an overview of the different mechanisms
   showing what technologies are common.  The document starts with a
   diagram showing the various components and how they go together to
   form five enrollment scenarios.
