IPv6 over DSL- Deployment Scenarios - : IPv6 over DSL - Deployment Scenarios - Franck Leclercq, 6WIND VP sales Asia-Pacific


Deployment steps : 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 How will IPv6 change the world?


DSL Deployment : 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... : 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 : 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 IPv6, a chance for the Internet


Conclusion : 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.
