Abstract

   This document defines a Dynamic Host Configuration Protocol (DHCP)
   option that will be used to configure various devices deployed within
   CableLabs architectures.  Specifically, the document describes DHCP
   option content that will be used to configure one class of CableLabs
   client device: a PacketCable Media Terminal Adapter (MTA).  The
   option content defined within this document will be extended as
   future CableLabs client devices are developed.

3.  Introduction

   Cable Television Laboratories, Inc. (CableLabs) is a non-profit
   research and development consortium that serves the cable television
   industry via design and specification of new and emerging broadband
   service architectures.  Several CableLabs initiatives define DHCP
   clients that have specific DHCP configuration requirements.  One such
   initiative is the PacketCable project.

   The PacketCable project is aimed at architecting, qualifying, and
   supporting Internet-based multimedia services over cable-based packet
   networks.  These new multimedia services will include telephony and
   videoconferencing, delivered using the basic Internet Protocol (IP)
