Introducing IPV6 involves the fundamental network, service network, terminal, support system, CP,SP, government and media

CT’s goal in the next two yearsIP backbone IPV6 ready

All the purchased terminals are equipped with IPV6

CT’s Target

IPV6 access ready in some MANs

1~2 self-running services fulfill end-to-end IPV6 service

1~2 sample MANs are able to provide end-toend IPV6 services

TOP 10 ICPs are IPV6 ready

What are the principles?Network-wide IPV6

Target Principle

1

Protecting InvestmentKeeping user experience Reducing impact on network

2

Fundamental Networks come first Service Networks soon after CP/SPs come later

Minimizing price3 Conducting tests at selected points come first Popularizing all-around come after

4 Existing services need to be seamlessly moved New services need to be IPV6 enabled directly

The details of deployment policy--networkBackbone MAN Support System

Backbones use dualstack for transiting, both core and aggregation network;

MAN use dual stack for transition. Most of the subscribers will use dual stack connection and a small number of subscribers will use tunnel in case they don’t have IPV6 ability. For small number of applications, protocol translation mechanisms will be put into use.

Old DNS software system’s need to upgrade to support IPV6 record. The new built DNS are required to support IPV6 access. The new built dual-stack Network management system should support IPV6 MIB database. AAA system doesn’t need be changed, only need supporting IPV6 subscriber certification by software upgrading.

Third-party CP/SP

New services should be IPV6 enabled as early as possible, while existing service should be support IPV6 gradually by upgrading. For those platforms which are directly exchanging information with the client terminals should be IPV6 ready as quickly as possible. On the other hand, back-end management systems are not so urgent.

Mobile core Network and Soft-switching Network should be transited to IPV6 gradually according to the requirement of services. The new built IMS system should be equipped with

IPV6 directly .

CT should push the government to work out mandatory policies to give incentives to the CP/SP to introduce IPV6.

CT’s trial--CNGI

CT started CNGI since 2003 Network testing platform includes core network、management center ,exchange center and 7 residential network; Applications on Service gateway, service platform and P2P have been researched on the testing platform; CT made some studies on IPV6 introduction solutions collaborating with suppliers (eg. cisco, huawei)
