Scenario of IPv6 Transition Technologies Selection
draft-yang-v6ops-ipv6tran-select-03
Abstract
Many IPv6 transition technologies has been proposed, such
as Dual-Stack, 6rd and so on. An CPE may support some of
them instead of only one. But the ISPs always support different kinds
of transition technologies. So they must control all the CPEs to
match the exact transition tech through the CPEs' management system
or configuring them before issuing to the customers.

1. Problem Statement
Nowadays, many IPv6 transitioning technologies has been proposed such
as Dual-Stack, DS-Lite, 6rd and so on. Each of them proposes
individual requirment to the CPEs. To promote the competitive
ability of products,the CPE manufacturers certainly will try to
support more technologies as much as possible. Meanwhile, the
operators tend to use single or less technologies. Moreover, users
can buy and use their own equipments instead of using the one which
operator gives them, that will bring the diversity of CPEs.
Assume that an operator uses one or more transitioning strategies in its
network. There are two ways to make the CPEs available. The first
one is to make a pre-configuration for each CPE in advance. But,
when the users modify the configuration or change to their own
equipment, the connection will fail. The Second method is to deploy
Network Management System (NMS) to configurate all the CPEs. Various
CPEs from different manufactories usually need different NMS which
means either the operator needs to maintains multiple NMS in their
network or operator can only use one manufacturer's product in a
subnet. What's worse, when users buy and use their own CPE instead
of using the original one, there will be no any solutions to
configurate correctly except visiting service.
Some specific messages need to be define between CPE and DHCP Server
to communicate the IPv6 transition technologies.
