IPv6@home

• Many nodes!

• 128-bit addresses• Hierarchy• Multiple addresses• DNS

IPv6 at Home

• “Just plug it in…”

• Autoconfiguration, AC– Neighbor Discovery– Stateless AC (router ads)– Stateful AC (DHCPv6)

• Related technologies– Jini (Sun)– UPnP (Microsoft)

Plug and Play

Router Advertisements

IPv6 at HomeMobility

• Future devices will be mobile

• Autoconfiguration• Security• Mobile IPv6

IPv6 at HomeMultimedia

• Convergence of telephony, radio, TV...

• High performance– optimized design– “Jumbograms”

• QoS• Multicasting

IPv6 at HomeSecurity

• Important!– Autoconfiguration– Mobility– E-commerce

• Native IPsec– Authentication– Encryption

IPv6 TransitionMechanisms

• IPv4 connectivity– NAT-PT– SOCKS/proxies– Dual-Stack (AIIH)

• IPv6 connectivity– 6to4– 6over4

• Old applications– Bump in the Stack (BIS)

Conclusions

+ IPv6 delivers all required functionality+ Transition mechanisms

- IPv6 still work in progress- Few IPv6 implementations

Too immature to deploy!

IPv6@home

Future Work

• Follow the development• Additional IPv6 projects/thesis works• Always consider IPv6 in future projects• IPv6 implementations
