2 Today s Internet IPv4 Address space with IPv4 is being rapidly depleted Stanford or MIT have more addresses than China The requirements of the wireless world are huge 1billion cellular terminals in billion cars in 2004? Billion Internet appliances in 20?? Strong world-wide wide political support to move to IPv6 All major software firms have announced IPv6- enabled products All major manufacturers are gearing up to be IPv6 ready

3 Next Generation Internet IPv6 Addressing space is the most visible feature of IPv6. IPv6 uses 128 bits addresses es,, pushing the theoretical limi of unique IPv6 nodes to about 340 billion billion billion billion unique addresses! A must to implement always-on, 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. e economy.

7 Where are we going with IPv4? IPv4 is leading us to a world that encourages walled gardens and information barriers, discouraging innovation. NAT-induced, work-arounds, digital divide, etc. There is still no IPv6 killer application,, but restoring the true Internet will allow another wave of evolution, innovation and creativity.

8 Where are we Today with IPv6? IPv6 is a mature technology Stable base standards (still being polished, as with IPv4!) Stable products (routers & operating systems, etc.) Emerging ISP support Large stable public domain applications Emerging commercial applications and middleware IPv6 is a committed technology Required for full 3G deployment Required by defence industry Required by emerging markets and economies Required for further innovation Required to mitigate the digital divide

9 IP(v6) Convering Digital World

10 IP(v6) Digital Home

11 Ultra Wide Band: full-spectrum wireless Wi-Fi took home networking in 2003, and expect its popularity to grow in will also usher in a new wireless technology that is already beginning to steal Wi-Fi's thunder. With speeds approaching 500Mbps, UWB promises to deliver the bandwidth-intensive intensive multimedia applications of the connected home. Expect to see UWB technology in flat-panel monitors and entertainment centres by year's end. Wouldn't it be nice if cameras, computers, PDAs,, MP3 players, TVs, and printers could all automatically recognize each other and configure themselves to join your home network? YES, with a new version, UPnP 2.0, that will include

12 Broadband IPv6 World-Wide

13 Some Recent Press News (I) ISPs ignore IP timebomb, ISPs are storing up trouble by ignoring IPv6 [ ] The predicted surge in users signing up for "always-on" broadband connections will force service providers to upgrade to IPv6 in the next few years. Service providers could do the simple, short-lived thing, duplicating and extending their existing IPv4-based services. But in a year or two they will run out of addresses... The broadband 'explosion' is still a relatively manageable number, but not for long Mobile vendor unveils first IPv4/IPv6 handset [11 [ ] The growth in internet-connected mobile devices and emerging internet markets, especially in the Asia-Pacific region, requires a change in standards. Interim fixes like NAT will, according to the vendor, work reasonably well for fixed devices. But they will create additional problems for mobile devices which can

14 Some Recent Press News (II) Verio Starts Commercial IPv6 Services in North America [ ] The Chinese government announced that it will help Chinese service providers in building IPv6-based next generation infrastructure on a national scale [ ] 2003] NTT East announced that it will start commercial IPv4/IPv6 dual stack service at the beginning of 2004 [ ]. 2003]. US Commerce Dept launched Notice of Inquiry to examine the issues implicated by the deployment of IPv6 in the United States [ ]. France Telecom has a roadmap that will lead to general deployment in 2004 of the dual stack option across the entire network (core and access) [P. Release, 15 Jan 04]

15 Some Recent Press News (III) Telefónica introduced the first services based on IPv6 technology, during the IPv6 Global Launch Event,, under the organization of the European Commission. Its IP backbone, already has fully equipped nodes to provide IPv6 international access integrating communication services between Europe and Latin America through IPv6 [P. Release, ] 04] Web-enabled enabled lamp casts light on IPv6,, Matsushita has announced a desk lamp that sets up an IPv6 Internet address and can be controlled through a LAN [ ] Japan, China and South Korea are reportedly planning to jointly develop IPv6, in a move that will challenge the US- dominated market for current IPv4-based Internet technology [ ]. E-CH, the association recommending standards for egovernment in Switzerland, is working on a document tha will recommend the introduction of IPv6 capable systems [ ].

16 Commercial IPv6 Services Expand Further in Japan [Oct. 2003] mpanies/services Experimental/Commercial Access Technology Connectivity Type 6/IPv4 Dual Stack Service Commercial Dedicated Line dual stack gan in November Dedicated line connectivity at 1.5Mbps, 128Mbps, 64Mbps. Monthly fee is 117,000 yen for Mbps with 6 IPv6 addresses, for example. 6 Native Service Commercial Dedicated Line native 6-only connectivity through 1.5Mbps, 128Kbps, 64Kbps dedicated lines. No extra charge for IPv6. 6 Gateway Service Commercial Dedicated Line native ative IPv6 connectivity service for service providers, with IPv6 address block assignment up to /40 based on the need e clients can also use the address blocks if directly assigned by APNIC. Charge is determined on a negotiation basis. 6 Tunneling Service Commercial Dedicated Line, DSL, FTTH, ISDN IPv6 over IPv4 tunnelin 6 connectivity service for NTT Communications users. It is offered through a variety of access technology, including

19 Conclusions Digital convergence is happening IP is becoming the unifying services architecture IPv6 resolves address limitations of IPv4 IPv6 also enables new services which cannot be implemented with IPv4 Always-on for every human being, Peer-to-Peer connectivity on global scale, etc. Challenges of mobile and wireless Internet can only be met by IPv6 IPv4 provides costly, limited, inefficient, insecure, patchy alternative

20 Conclusions (II) Strong worldwide political support to IPv6 Visibility of IPv6 reached unprecedented levels in political circles. More strategic thinking and global approaches are needed. Co-operation at National and International level is highly desirable. The European IPv6 TF and the Regional/National TFs are instrumental in paving the road ahead for IPv6. IPv6 transition has already started
