          Next Generation Internet – IPv6

•   Address space with IPv4 is being depleted
•   Addressing space is the most visible feature of IPv6.
•   IPv6 uses 128 bits addresses, pushing the                theoretical limit of
    unique IPv6 nodes to about 340 billion billion billion billion unique
    • A must to implement “always-on”, mobility, peer-to-peer communications,
       machine-to-machine communications,...

•   Other significant capabilities of IPv6 include:
    • Integrated quality of service (QoS),
    • Reintroduces end-to-end security,
    • Automatic configuration (plug and play), data multicasting,
    • More efficient network route aggregation at the global backbone level.
    • ...
   IPv6 is a key issue on the road ahead to the e-economy.
           Some recent tidbits
“There is a kind of capacity problem. How is the Net going to support
billions of additional users and devices, and new data-hungry
        Vint Cerf (Intel Development Conference, San Francisco sept 2004)

« …the PC-centric era is fast giving way to the wireless age. The trend is
most apparent in Asia where cellphones with Net access are the
computing gizmo of choice. There are about 10x more cell phones capable
of handling e-mail and Web surfing being sold than PCs

…… China is planning to adopt IPv6 more rapidly than any other country in
the world. And if Huawei’s close ties to the Chinese Government help it
become the early leader in the technology, it could get the jump on rivals
such as Cisco, Alcatel and Lucent.. »

 Some perceived IPv6 drivers
• Mobile IP
• Peer 2 peer networking
• Peer 2 peer gaming
• Peer 2 peer voice over IP
• RFID networks
• Sensor networks
• Critical mass of digital end-user devices
• Critical Mass of ADSL and cable digital access
• Wi-Fi, Wi-Max, Mobile tech, Zigbee….

• National policies and economic weight

           Mobile IP as IPv6 driver

•   Mobile nodes must be able to move from router to
    router without losing end-to-end connection
    • A home address to maintain connectivity
    • Many,many care-of address to maintains route-ability
•   billions of care-of addresses needed in the future:
    forget v4

        Peer to peer networking as IPv6

•   Entertainment content sharing
    • Napster, Kazaa, Morpheus,
    • Grokster, Gnutella …

•   Science content sharing
    • Quarknet
    • SDSS
    • Neptune…

•   Distributed data processing
    • SETI@home
    • Folding@home                Sloan Digital Sky

            Peer to peer VoIP
             as IPv6 Driver ?

•   Aug 29th 2003: Skype set up in Stockholm by Niklas Zennstrom
    and Janus Friis, founders of Kazaa. Promises high quality p2p
    phone calls over the internet to always-on customers (ADSL
    and cable).
•   April 6th 2004: launches PocketSkype for Wi-Fi hotspot access
•   Based on e2e VoIP, a good algorithm for voice, PC’s with
•   “We have a big ambition with Skype: it is to make it the global
    telephone company” (Int’l Herald Tribune oct 13th 2003).
•   July 2004: Teleglobe, Level3, iBasis provide Skype PSTN
•   Skype reaches 28 million users

            P2P gaming as IPv6 Driver

•   Gaming market is projected to exceed $5
    billion by 2006.
•   On line gaming today is mostly
    client/server: creates serious bandwidth
    and processing bottlenecks
•   Xbox and Playstation are IPv6 ready
•   Korea’s Ncsoft becomes the number one
    on-line game developer.

           RFID’s as IPv6 driver

•   Current RFID’s contain 18 bytes of data.
•   Wal-Mart Stores Inc.'s top 100 suppliers already attach RFID
    tags to shipping pallets so the chain can track shipments; all
    suppliers by 2006.
•   Generalized use of RFID implies terabytes of traffic daily.
•   RFID tags considered for passports and even banknotes
•   IATA might mandate RFID as baggage tags
•   RFID in casino chips in Vegas!

      Sensor networks as IPv6 driver

•   Self organizing sensor networks (DARPA Sensit
•   Smart Dust and follow-up projects : Goal is
    autonomous sensing and communication in a cubic
•   Intel Deep Network projects
    • “Locally networking billions of embedded nodes, driving
      computing deeper into the infrastructure that surrounds us.”

    • Radio Free Intel : vision of adding wireless capabilities to every
      device by integrating the radio circuits and systems directly into
      every component
•   Intel’s Planetlab?

         «Countdown to a battle for the
         living room »(Financial Times Jan 14th 2004)

•   The Consumer Electronic show in Vegas early January
    saw the first serious salvos in what could be a titanic
    battle between the computer industry (Intel, Microsoft)
    and the electronics industry (Sony, Philips, Toshiba,
    • The essence of the battle is a kind of a home « mediacenter » with
      all devices connected in a plug and play mode, preferably wireless.
    • « once music, video, photography and mobile telephone become
      digitized, recording, replaying and editing become an exercise in
      applied computing »
•   Sony had already announced that starting 2005 all its
    products will be IPv6 enabled. The Microsoft Xbox also.
    Let the battle start!
IP(v6) Digital Home

IP(v6) Convering Digital World

       Wi-Fi, Wi-Max, ZigBee, Mobile-Fi,

•   Will the convergence of
    cellular telephony and IP
    come on the heels of fixed
    line telephony and IP?

•   VoIP is considered disruptive
    for fixed line carriers business
    models at this stage.
    Will cellular telephony be the
    next battlefront?

      broadband connection, allowing all students and
      teachers to have access to online knowledge and
      educational resources

     This measure will be complemented by the
      development of an education resource databank
      and the installation of 1 PC per classroom

2   CPE is IPv6 compliant

    IPv6 including its meaning.
•   Overall, respondents of this survey have a high
    interest or awareness on IPv6.
