  1. UK Call for Action on IPv6 Peter Kirstein Kirstein@cs.ucl.ac.uk DTI Briefing on IPv6, 30-04-03

  2. What are the Advantages of IPv6 • Larger Address Size than IPv4 • 1970 – 256 Hosts (Arpanet) • 1980 – 4B Hosts (Internet, IPv4) • 2004 – at least 16 BB (Internet IPv6 as used) • Much more consistent services than IPv4 • End-end security (IPsec) • Good Mobility Support (MIPv6) • Uniform support for Multicast • Proper support in Packet for Quality of Service • Easier re-configurabilty DTI Briefing on IPv6, 30-04-03

  3. The Principal Benefits • The larger address space will be essential • The only question is whether it is required for 2005 or 2008 in the UK • It is already required in the Pacific Rim • It will be required almost immediately anywhere one wishes to install wireless access on an appreciable scale • Security, Mobility, QoS and Multicast could be provided over IPv4 • Because they were added on later, they are not consistent over IPv4; that must wait for IPv6 • Ease of re-configurability depends on lower 64 bits unique to the device, upper the network DTI Briefing on IPv6, 30-04-03

  4. The Stages of IPv6 • Development of Standards – 92-03 • Ratification of standards – 99-04 • Preparation of enabling technologies – 97-05 • Pilot R & D projects – 97-03 • Pilot deployment Projects 01-04 • Adoption for key applications 02-06 • Marketing pull from early developers 01-06 • Commercial Deployment 04-08 • Mobile from around 2005, but see later slide DTI Briefing on IPv6, 30-04-03

  5. The Status • IPv6 is not at the Bleeding edge in early 2003, though it is still at the Leading edge • Many current applications now run under IPv6 – but do not really use its advantages • Most large suppliers now have pretty good iPv6 stacks and support in their products • Though this support is still improving regularly • The wide-scale adoption of IPv6 will have major impact on applications and usage • It will require many years experience to understand nature DTI Briefing on IPv6, 30-04-03

  6. Enabling Technology - Projects • KAME – Japanese financed, FreeBSD 96-03 • USAGI – Japanese financed Linux successor • Developed pre-commercial reference implements • Japan/Korea has have projects on deployment of network and applications for 5 years • The European Commission has supported R & D projects for about three years • Some European countries have had enabling projects DTI Briefing on IPv6, 30-04-03

  7. Enabling Technologies -Commercial • Early work on prototypes 98-01 – US, Japan • Sun, Cisco, IBM, Microsoft • Early products 99-01- mainly non-US • Hitachi, 6WIND, Ericsson … • Sun introduced steadily into products • Main release since 01, Java-enabled since 02 • Cisco lost chance to bid to NTT in 01 • Mounted a major (and successful) catch-up DTI Briefing on IPv6, 30-04-03

  8. Pilot Deployments in NRENs • Large Japanese, some US, lesser Korean • Substantial Deployments in European NRENs • French RENATER, Dutch SURFNET, German DFN • European GEANT running dual stack, with links to Internet 2 and the Japanese WIDE • British two years behind the leaders, coming in slowly • British BERMUDA half person 3 universities 00-02 • European projects mainly EC • 6NET and Euro6IX looking at what is still missing • Unlike our neighbours almost no UK funding or promotion DTI Briefing on IPv6, 30-04-03

  9. The Mobile World • 3GPP has agreed to adopt IPv6 from Release 5 • Limited part of standard, mainly packet format and SIP, not IPsec, Multicast, RTP and multimedia • Problem with UMTS slowed down interest • Had intended to already move to IPv6 deployment • Mobile operators only adopting part of IPv6 • UMTS will use more only under customer pressure • WIFI may well adopt it more fully than UMTS – causing problems for uses wanting uniform access DTI Briefing on IPv6, 30-04-03

  10. British Involvement in IPv6 • Small-scale UK university activity from UK sources • Lancaster U, Southampton U, UCL (BERMUDA, UKERNA) • Strong UK academic involvement in European projects • Little commercial though some, e.g. BT strongly involved • Negligible Involvement of defence or health • With outsourcing of communications, these UK agencies consider any activity should be undertaken by industry • Some Dstl involvement in INSC, but only studies • Good Lancaster involvement with US industry • Cisco and Micosoft mainly on mobile IP and testbed DTI Briefing on IPv6, 30-04-03

  11. IPv6 Task Forces • Japanese/Korean initiatives at high level, IPv6 Task Forces almost incidental • US White Paper from White House • US Task Force industry and government backed • European Task Force some backing from EC • Central funding for European-level activities • Roadmaps on developments • Proposals for R & D and other measures • Several National Task Forces • French, German, Swiss, Spanish ….. • Normally government and industry backed • UK Government waiting for lead from UK industry DTI Briefing on IPv6, 30-04-03

  12. Ad Hoc UK Task Force • Prof Peter Kirstein (Chairman) • Christian de Larrinaga (Director) • Dr. Tim Chown (Secretary) • Peter Hovell (Treasurer) • High sounding – but not that active yet. Problem that there is nobody with full-time commitment DTI Briefing on IPv6, 30-04-03

  13. Activities of Task Force • An early meeting of the Task Force attracted representatives from: • BT Exact, Cisco, NTT, Xchangepoint, LINX, Microsoft, IBM, UKERNA, U. of Southampton, University College London, U. of Lancaster, CESG, Network Brokers • Interest in the Task Force has been expressed by over 200 interested professionals • Should be co-ordinating UK-orientated IPv6 initiatives through • Trials, Research, EU participation, Events • Needs at least one dedicated staff member, and some resources to mount events DTI Briefing on IPv6, 30-04-03

  14. Does the lack of National Activity matter? • There has been concern that there are few IPv6-enabled applications • This is the least of the problems, porting to allow apps to work under IPv6 is fairly easy • Making them take full advantage of IPv6 is much harder, and needs commitment from large communities like Defence, NHS, Transport etc. • Our competitors are starting to get this experience, we are not DTI Briefing on IPv6, 30-04-03

  15. The International Scene • Most major US suppliers are now ready to provide IPv6 facilities • Government has already given seed money • Many getting applications experience in Europe • Traditionally they use own commercial funds • Both Japan and Korea have funding of more than $100M for developing applications and deployments • Europeans have many projects – but very limited UK commercial deployment – mainly BT DTI Briefing on IPv6, 30-04-03

  16. British Problems with IPv6 • The supplier industry has little development funds often rely on customer to sponsor R &D awareness • The large user organisations – e.g. Defence, Transport, NHS have outsourced their computing, communications and networks • They expect suppliers to do the R & D; the suppliers are waiting for the requirement and finance from agencies • Many shortcomings of IPv4 can be patched up in the short-term by the suppliers • Specific problems often cheaper to fix the IPv4 rather than consider moving to IPv6 – and profitable to the fixer DTI Briefing on IPv6, 30-04-03

  17. Longer Term Problems • We have major procurements – e.g. for the NHS • Previous NHSnet must be completely replaced • Could not consider moving to IPv6 now, but will need IPv6 in normal lifetime of this new net • Should be considering at least the need to transition • Should be in a position to specify what aspects are important to ease the transition • Without obtaining experience now, we will be in the same state in 2010 when upgrade is needed DTI Briefing on IPv6, 30-04-03

  18. UK Needs • Needs someone with a full-time commitment to bring up the awareness of IPv6 at all levels • Should service awareness events • Should be committed to further British involvement at all levels • In view of outsourcing, should be in position to propose pump-priming • Includes bringing in IPv6 in areas like Grid • Currently there is almost no UK focus DTI Briefing on IPv6, 30-04-03

  19. The Way Forward • If we sit on the fence, we will regret it • If there is no National demand for action, we will continue to sit on the fence • Industry should be more active from own funds and in European projects • Government and large users should be more proactive in understanding the impact • Training & Awareness activities should be funded • Some from Industry should feel ownership, from government responsibility and users concern DTI Briefing on IPv6, 30-04-03
