Abstract

   This document provides a detailed description of IPv6 deployment and
   integration methods and scenarios in wireless broadband access
   networks in coexistence with deployed IPv4 services.  In this
   document, we will discuss the main components of IPv6 IEEE 802.16
   access networks and their differences from IPv4 IEEE 802.16 networks
   and how IPv6 is deployed and integrated in each of the IEEE 802.16
   technologies.

RFC 5181            IPv6 over IEEE 802.16 Scenarios             May 2008

1.  Introduction

   As the deployment of IEEE 802.16 access networks progresses, users
   will be connected to IPv6 networks.  While the IEEE 802.16 standard
   defines the encapsulation of an IPv4/IPv6 datagram in an IEEE 802.16
   Media Access Control (MAC) payload, a complete description of IPv4/
   IPv6 operation and deployment is not present.  The IEEE 802.16
   standards are limited to L1 and L2, so they may be used within any
   number of IP network architectures and scenarios.  In this document,
   we will discuss the main components of IPv6 IEEE 802.16 access
   networks and their differences from IPv4 IEEE 802.16 networks and how
   IPv6 is deployed and integrated in each of the IEEE 802.16
   technologies.

   This document extends the work of [RFC4779] and follows the structure
   and common terminology of that document.

1.1.  Terminology

   The IEEE 802.16-related terminologies in this document are to be
   interpreted as described in [RFC5154].

   o  Subscriber Station (SS): An end-user equipment that provides
      connectivity to the 802.16 networks.  It can be either fixed/
      nomadic or mobile equipment.  In a mobile environment, SS
      represents the Mobile Subscriber Station (MS) introduced in
      [IEEE802.16e].

   o  Base Station (BS): A generalized equipment set providing
      connectivity, management, and control between the subscriber
      station and the 802.16 networks.

   o  Access Router (AR): An entity that performs an IP routing function
      to provide IP connectivity for a subscriber station (SS or MS).

   o  Connection Identifier (CID): A 16-bit value that identifies a
      connection to equivalent peers in the 802.16 MAC of the SS(MS) and
      BS.

   o  Ethernet CS (Convergence Sublayer): 802.3/Ethernet CS-specific
      part of the Packet CS defined in 802.16 STD.

   o  IPv6 CS (Convergence Sublayer): IPv6-specific subpart of the
      Packet CS, Classifier 2 (Packet, IPv6) defined in 802.16 STD.
