lca2011 – day3 – keynote

Geoff Huston

  • New technologies from the 70s – Unix and Packet switching (TCP/IP)
  • Open technologies – anyone can implement
  • TCP/IP not better than competing technologies but it’s openness greatly helped it win
  • One thing to “be open” , another to “stay open”
  • Useful technologies are rarely static
  • Technology evolves, uses change (eg growth of wireless), exploitation models change
  • Challenges – net neutrality, next generation networks, mobility and mobil service evolution, Triple/Quad play schemes
  • The really important thing is “We are running out of addresses”
  • 190 m addresses given out in 2009, 248m in 2010
  • 300million new things on the network
  • 9 million new addresses just in Australia
  • 7 /8s left, rate of 1/month
  • plan that IPv6 transition would happen before ipv4 ran out
  • Only 0.3% hitting google IPv6
  • IPv4 will run out during 2011/2012
  • Need to transition to ipv6 in 200 days
  • Won’t happen, have to muddle thing with ipv4
  • NATs are an externalized problem
  • ISP NATs, multi-level, within ISP network
  • aperture through through which the Internet can be seen and used. Reduced port space
  • transition to ipv6. Dual stack requires everybody to have a ipv4 address
  • If you run 6to4 15% of connections don’t connect.
  • Transition could take 5-40 years
  • Making ipv4 addresses last longer, they will cost
  • TCP/IP is the network monoculture
  • Will openness be lost in the transition?
  • Telcos being asking to make big investment in ipv6. No really in their interests to have an open network.
  • Similar for large Internet companies like google and amazon
  • Delays help the incumbents, open network infrastructure is at risk
  • Need to figure out how to motivate big companies to goto ipv6 and open infrastructure
