IPv6 in GEANT – 6DISS workshop, March 2006
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
IPv6 in GEANT – 6DISS workshop, March 2006
• 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
IPv6 implementation on GEANT

IPv6 Connectivity in GÉANT
IPv6 in GEANT – 6DISS workshop, March 2006
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
IPv6 in GEANT – 6DISS workshop, March 2006
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)
IPv6 in GEANT – 6DISS workshop, March 2006
• ESnet (US) => Native link
• Ca-net (CA) => Native in two links
• SInet (JP) => Tunnel in New York
IPv6 connectivity to non-EU Research Networks (II)
IPv6 in GEANT – 6DISS workshop, March 2006
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

IPv6 Traffic in GÉANT
IPv6 in GEANT – 6DISS workshop, March 2006
NREN IPv6 total traffic volume
IPv6 in GEANT – 6DISS workshop, March 2006
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)
IPv6 Vs IPv4 Traffic volume
IPv6 in GEANT – 6DISS workshop, March 2006
Multicast IPv6
IPv6 in GEANT – 6DISS workshop, March 2006
Multicast IPv6 in GÉANT
• 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
IPv6 in GEANT – 6DISS workshop, March 2006
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 7.0Needs to be deployed in all the domains
other vendors such as Cisco also support it
IPv6 in GEANT – 6DISS workshop, March 2006
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
