TDP Transition Data Plane
4 IPv6-based SDN & NFV Deployment
4.1 Introduction
The exhaustion of the IPv4 address space has been a practical problem that providers are facing today. The migration to
IPv6 is ongoing and picking up steam throughout the world.
Depending on the amount of technology debt and legacy present in the existing infrastructure, the IPv6 transition might
require significant upgrades and different approaches to the roll-out in order to maintain efficiency. Instrumentation and
operational tools, back-end systems and processes will also need to be updated for the new protocol. Therefore,
operators might have to upgrade network devices to support different transition strategies but more importantly to
support different visions of the future infrastructure. The transition will increase the OPEX and CAPEX needs during
the transition. The increase will be determined by the specifics of the provider and particularly by the speed with which
the provider chooses or is forced to execute the transition.
One option is to consider managing the transition by using SDN/NFV concepts and technologies. A unified Transition
Data Plane (TDP) enables DevOps in IT environment by providing extensibility via programmability, by integrating
deployment and operation into the implementation, and by streamlining OSS. The IPv6 transition can be viewed as
another service enablement exercise managed by TDP. In a TDP enabled environment, an IPv6 transition powered by
SDN could lower the deployment and operational costs by decoupling the data plane and control plane, and by
providing unified data plane devices. It also nurtures the development of native IPv6 services through the availability of
open Northbound APIs. An Open IPv6 can reduce the operational complexity and risk via the unified data plane which
adapts to different transition scenarios.
4.2 Unified Openv6 Use case
4.2.1 Evolve from one Scenario to Another
During the IPv6 transition period, the network will go through three stages: IPv4-only network, dual-stack network and
IPv6-only network. The network should support both IPv4 services and IPv6 services at each stage.
There are multiple IPv6 transition technologies for different network scenarios (e.g. IPv4 network for IPv4/IPv6 user
access, IPv6 network for IPv4/IPv6 user access, IPv4 servers for IPv6 visitors, etc.). Different network scenarios will
