Results and Conclusions
18
Lessons learned (1)

• 6WINIT identified several applications which
  benefit from new higher bandwidth wireless
  networks and IPv6 (in the long term) but
  currently lack of commercial interest
• 6WINIT was optimistic regarding wireless IPv6
• in practice native v6 only in WLAN, tunnelled in
  GPRS (UK) and UMTS (Stockholm)
• in Finland no GPRS (NATs and firewalls)
• IPv6 networks work sufficiently (usually)
• remote access to home environment has been
  demonstrated from China, Tunisia, USA,

19
Lessons learned (2)

• IPv6 software is still buggy
• IBM OSGi (Java-based) IPv6 URL handling
• Java Media Framework lots of problems with IPv6
  streams
• autoconfiguration problems on some hardware
• Apache had problems with IPv6 virtual hosts
• There are lots of missing pieces
• IPv4 only software
• ease of use
• testing!!!

20
We need IPv6 but how do we get it?

• Students, nerds etc. should be able to play with
  IPv6
• free testers, possibility of new innovations
• Research world uses and promotes IPv6
• it is a good tool for networking research
• EU supports IPv6 projects (not entirely good
  thing)
• Production/commercial use?
• it is difficult to show that IPv6 is useful
  benefits are largely invisible to the end users,
  implementation is not easy
• starts from some IPv6 friendly islands (e.g. 3/4G
  wireless networks, Asia, )
