Deployment stepsDeployment steps

• Products are available today SW & HW

• Numerous legacy applications are running on v6, others are arriving

• IPv6 is progressively integrated into network architecturesWith the goal to provide value added services

• IPv6 will progressively arrive in corporations and houses with the new OS versions and applications

• 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

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

ConclusionConclusion

• 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.
