  1. IPv6 in GÉANT DANTE – Ana Romero 6DISS workshop, March 2006 Kopaonik Presenting: János Mohácsi NIIF/HUNGARNET

  2. GÉANT2 pan-European Research Network successor to GÉANT • Connecting 34 • European Countries • and 30 NRENs • Mixture of leased circuits and dark fibre to provision current high bandwidth demands • Juniper routers and Alcatel optical equipment Backbone topology from Aug 2005

  3. IPv6 implementation on GEANT • Implementation of dual stack in all GEANT backbone in early 2003 • First NRENs v6 connected in spring 2003 – Renater (.fr) and RedIRIS (.es) • GEANT IPv6 service operational since Oct 2003

  4. IPv6 Connectivity in GÉANT

  5. IPv6 connectivity to NRENs • 30 out of 31 NRENs connected • 27 out of 30 are native connections • rest are tunnels • ~580 routes announced to NRENs • Only 2000::/4 prefixes between /19-/35 permitted

  6. IPv6 connectivity to non-EU Research Networks (I) • Abilene (US) => All native connections – examples of connectivity: - ARIN Region: DoD (22), VBNS (145), Univ.Wiscosin (2381), Univ.Indiana (22398) • CLARA (LatinAmerica) => Native • LACNIC Region: RNP (1916), Retina (3597) • TEIN2 (South East Asia) => Native • APNIC Region: Australia NREN (7570), Singapore NREN (7610)

  7. IPv6 connectivity to non-EU Research Networks (II) • ESnet (US) => Native link • Ca-net (CA) => Native in two links • SInet (JP) => Tunnel in New York

  8. IPv6 connectivity to ISP • Providing free interconnection for European NRNs to the whole v6 internet • Tunnel connections with ISPs • Encouraging ISP to develop their networks in IPv6 • Access to commercial IPv6 networks

  9. IPv6 Traffic in GÉANT

  10. NREN IPv6 total traffic volume

  11. IPv6 Vs IPv4 Traffic volume GÉANT v6 traffic volume:2% IPv6 of the total traffic IPv6 daily traffic stats for SWITCH access to GÉANT Daily total traffic stats for SWITCH access into GÉANT Daily statistics from one of the most IPv6 users in GÉANT: SWITCH (.ch) with average of 50% total traffic in IPv6 (in outbound traffic)

  12. Multicast IPv6

  13. Native Multicast IPv6 across GÉANT backbone Pilot service ready since early 2005 Test done in 2004 in collaboration with Multicast v6 TF Request for specific multicast v6 features to Juniper Several NRENs connected to the multicast IPv6 enable core 12 NRENs already connected - 7 in native, rest in tunnels Connectivity to M6bone via Renater Native connectivity to Abilene Multicast IPv6 in GÉANT

  14. Future plans: Embedded RP • Interdomain multicast IPv6: implementing embedded RP • interdomain solution where the RP can be selected when setting a session • Available in JUNOS since 7.0 • Needs to be deployed in all the domains • other vendors such as Cisco also support it

  15. Conclusions • GÉANT and NRENs leading IPv6 • Most of NREN IPv6 is deployed for a long time • Encouraging to see how v6 traffic grows • Work is still needed at the end user • small proportion of end users connected • develop IPv6 applications • Multicast IPv6: new technology • work needed in interdomain mcastv6 and applications
