IPv6

  • 128 bits of address space

340 X 1036 unique addresses

  • IPSEC not optional
  • Flow ID

Flow ID

  • ipv6.google.com (animated Google logo)

Mobility and Mobiles

  • 3.5 Billion Mobiles and counting (15% Internet enabled)
  • Text/Web Access
  • Payment systems
  • Innovative interfaces - Note I/O discovery
  • Navigation systems

– GPS, Galileo?, Mobile Tower triangulation, Bldg Announcements?

  • Geo-location based services

Internet-enabled Devices

slide-16
SLIDE 16

An Internet of Things

Programmable – Java, Python, etc. Examples: Examples:

  • WebTV, Personal Digital Assistants, Mobiles,Video games,

Picture Frames, Washing Machines, Surf Board!

  • Refrigerator (and the bathroom scales)
  • Automobiles
  • Internet-enabled wine corks (also note new quantum theory of

wine: Schrödinger’s wine bottle)

  • Internet-enabled socks (clothing)

( g)

  • Universal Remote Controls
  • Sensor Networks

Near Term Changes

  • IPv6 - 128 bit addresses (3.4 X 10^38)
  • DNSSEC (.se, .pr, .bg, .br, others?)

– Root zone a big issue g – Challenge for *.google.com

  • Internationalized Domain Names

– Non-Latin Unicode characters – ASCII Punycode encoding “xn--…” – Potential hazards (e.g. paypal, .py (paraguay or russia?))

  • New ccTLDs and gTLDs

– ISO 3166-1 (ASCII 2 char) -> iCCTLDs?

Cloud Collaboration

  • Multiple Data Centers (replication, responsiveness)

D i i h i

  • Dynamic capacity sharing
  • Data sharing (“latest copy is always in the cloud”
  • Video and audio conferencing with data sharing
  • Inter-Cloud interactions (new research area!)

– How to refer to other clouds? – How to refer to data in other clouds? – How to make data references persistent (unlike URLs)? – How to protect Clouds from various forms of attack (inside, outside)? – How to establish an access control regime (inside, between clouds)? – What semantics can we rely on with inter-cloud data exchange? – What notion of “object” would be useful for inter-cloud exchange?

Challenges of the Digital Age

  • Semantic Web
  • Complex objects that can only be rendered via computer

– 3D interactive objects j – Complex spreadsheets – Interactive environments

  • BIT ROT!

– Preserving interpretive programs (Windows 3000 and PPT 1997) – Preserving interpretive programs (Windows 3000 and PPT 1997) – And the operating systems that run them – And the hardware that run the operating systems p g y – For thousands of years!!

  • End-to-end information flow across the solar system
  • Layered architecture for evolvability and

interoperabilit interoperability

  • IP-like protocol suite tailored to operate over long

round trip light times

  • Integrated communications and navigation services
