  1. 1. A master thesis work by Christer Engman (e94_cen@e.kth.se) Network Services Telia Research AB Department of Teleinformatics Royal Institute of Technology IPv6@home
  2. 2. IPv6@home Agenda • Home Networking • IPv6 • IPv6 at Home • IPv6 Transition • Experiments • Conclusions
  3. 3. IPv6@home Home Networking Connect everything! Internet
  4. 4. IPv6@home IPv6 • Supersedes IPv4 • Appeared in 1992 • IPv4 “full” between 2005 and 2010 • Enhanced functionality Internet Protocol version 6 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 Year Deadline? Appearance Today
  5. 5. IPv6@home • Many nodes! • 128-bit addresses • Hierarchy • Multiple addresses • DNS IPv6 at Home Addressing 192.168.2.27 3ffe:0:2000:73b9:200:f8ff:fe32:5fc
  6. 6. IPv6@home 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
  7. 7. IPv6@home IPv6 at Home Mobility • Future devices will be mobile • Autoconfiguration • Security • Mobile IPv6 Router Mobile Node Internet Server Internet Home Server direct route tunnel
  8. 8. IPv6@home IPv6 at Home Multimedia • Convergence of telephony, radio, TV... • High performance – optimized design – “Jumbograms” • QoS • Multicasting
  9. 9. IPv6@home IPv6 at Home Security • Important! – Autoconfiguration – Mobility – E-commerce • Native IPsec – Authentication – Encryption
  10. 10. IPv6@home Strategy IPv6 Transition Core network Access network Access network Access network Home Networks IPv6 IPv4
  11. 11. IPv6@home IPv6 Transition Mechanisms • IPv4 connectivity – NAT-PT – SOCKS/proxies – Dual-Stack (AIIH) • IPv6 connectivity – 6to4 – 6over4 • Old applications – Bump in the Stack (BIS) IPv6 IPv4 + IPv6 IPv4
  12. 12. IPv6@home Experiments Lab network setup • IPv6 support • Connectivity • DNS • Transition mechanisms TRAB Intranet Linux Windows 98 Windows 2000 ipv6.trab.se
  13. 13. IPv6@home Conclusions + IPv6 delivers all required functionality + Transition mechanisms - IPv6 still work in progress - Few IPv6 implementations Too immature to deploy!
  14. 14. IPv6@home Future Work • Follow the development • Additional IPv6 projects/thesis works • Always consider IPv6 in future projects • IPv6 implementations
