IPv6 over DSL- Deployment Scenarios - Franck Leclercq, 6WIND VP sales Asia-Pacific
Deployment steps • Products are available today • SW & HW • Numerous legacy applications are running on v6, others are arriving • IPv6 is progressively integrated into network architectures • With the goal to provide value added services • IPv6 will progressively arrive in corporations and houses with the new OS versions and applications
How will IPv6 change the world? • Allowing • Peer-to-peer application deployment • VoIP, videoconferencing, content sharing, games… • Plug and Play • IP services have to become commodity services • IP connectivity everywhere at anytime • Efficient mobility • IP on all wireless technologies • Secured transfers
DSL Deployment • +25 Millions DSL Lines worldwide • 80% for residential users • Penetration of DSL(DSL Lines per 100 population) • South Korea 12.12 • Taiwan 6.28 • Japan 2.60 • France 1.24 • China 0.05 (www.point-topic.com)
IPv6 and DSL... • DSL => Always-On => more IP addresses needed • IPv6 128 bits address space is a solution to public IPv4 address shortage • DSL => Always-On => Peer-To-Peer • IPv6 allows end-to-end global connections with no NAT and stable addresses • DSL => Asia => IPv4 address shortage today • IPv6 is a solution for Internet access in Asia • DSL => Broadband Internet Access => Line Sharing • IPv6 address allocation mechanisms facilitate several public addresses behind a single DSL line
Come back to origin • IP was designed to allow end-to-end data transfers • Whatever the transmission technology • Offering a global addressing scheme • Implementing simple protocols and mechanisms

IPv6, a chance for the Internet • Restoration of the Internet model with IPv6 IPv6 IPv6 IPv6 IPv6 • Simple, stable network service • => higher performance, more robust, more secure, more manageable • Enabling anyone to offer new applications and services • => allowing rapid innovation and growth
Conclusion • IPv6 deployment could be done at different paces, either "aggressively" or "progressively" • IPv4-only, IPv6-only and IPv4+IPv6 subscribers can be mixed in the same ADSL zone. • IPv4 data path can be preserved under certain circumstances while moving to IPv4+IPv6 access • Both bridged and routed access could be envisaged for IPv4+IPv6. • Unlike for IPv4, bridged access for multiple IPv6 terminals is feasible due to the large IPv6 address space and the prefix allocation mechanisms • Subscriber’s management systems based on PPP and RADIUS for IPv4 can be reused while deploying IPv4+IPv6 access.
