IPv6 Transition Technologies Selection in NFV
draft-hui-v6ops-ipv6trans-select-nfv-00.txt
Abstract
Nowadays, many IPv6 transition technologies have been proposed, such
as Dual-Stack, 6rd and so on. A CPE may support some of them
instead of only one. But the ISPs always support different kinds of
transition technologies, such as Dual-Stack, DS-lite and so on. So
they must control all the CPEs to match the exact transition tech
through some standard messages. When the ISP network uses NFV, the
message communication will between the network gateway and the V-CPE
to configure the IPv6 transition technology in CPE.

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 requirement 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 NFV 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 configure all the CPEs. Various
CPEs from different manufactories usually need different NMS which
means either the operator needs to maintain 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
configure correctly except visiting service.
NFV makes the vCPE to control the CPE, so we need some messages to
configure the IPv6 transition tech between network gateway and vCPE.
