IPv6 Deployment Scenarios in 802.16 Networks
Status of This Memo
This memo provides information for the Internet community. It does
not specify an Internet standard of any kind. Distribution of this
memo is unlimited.
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.
