1. Academic and Research Network of Slovenia Static IPv6 in GÉANT and Internet2 LSR a joint effort by ARNES, DANTE, RedIRIS and Juniper TF-NGN meeting Budapest, 17-18 Oct 2002

2. Academic and Research Network of Slovenia GÉANT IPv6 deployment plan activity by the end of 2002 –dual-stacked routers in GÉANT –static IPv6 routes –part of these activities: IPv6 land speed tests dynamic routing in 2003

3. Academic and Research Network of Slovenia Members of the team ARNES –Avgust Jauk, Boštjan Lemut, Matjaž Straus DANTE –Agnès Pouélé, Roberto Sabatino RedIRIS –Esther Robles, David Martínez, Miguel Angel Sotos Rodriguez Juniper –Jean-Marc Uze, technical support (Bruno De Troch) and many others

4. Academic and Research Network of Slovenia IPv6 LSR preparation choosing hosts –hardware 1.1/1.3GHz 2xPIII CPU, 1GB RAM Intel PRO/1000 XT and 82543 GE Adapter –software Linux (2.4 kernel) iperf v1.62, wu-ftpd-2.6.2-/pure-ftpd-1.0.12-1, ncftp-3.1.3-4.ipv6.2 TCP stack parameters RAM disks Juniper routers –JUNOS 5.3R2.4 and 5.3R3.3 tested by DANTE –additional hardware: tunnel PIC (lent by Juniper)

5. Academic and Research Network of Slovenia IPv6 LSR test plan IPv4 performance tests IPv6-in-IPv4 tunnel –with test routers –with production routers native IPv6 –single stream and multiple stream –two paths: direct path Ljubljana – Madrid long path via New York

6. Academic and Research Network of Slovenia IPv6 LSR tunnel setup

7. Academic and Research Network of Slovenia IPv6 LSR first path SI-AT-CH-IT-ES 2518 km 62 ms RTT 480/490 Mb/s

8. Academic and Research Network of Slovenia IPv6 LSR second path SI-AT-NY-UK-FR- CH-IT-ES 14.800 km 229 ms RTT 350/400 Mb/s

9. Academic and Research Network of Slovenia IPv6 LSR second path on GEANT Link Level Topology (geant-msr-0209.pdf)

10. Academic and Research Network of Slovenia IPv6 LSR TCP stack short path –window size estimate: 60 ms  600 Mb/s  4.4MB –4MB not enough! –16MB used long path –window size estimate: 230 ms  600 Mb/s  17MB –16MB and 32MB used

11. Academic and Research Network of Slovenia IPv6 LSR results testtransfer rateLSR mark IPv4 460 Mb/s- IPv6 tunnel on test routers 430 Mb/s- IPv6 tunnel on production routers 370 Mb/s- IPv6 single stream 480 Mb/s1215 Tbm/s IPv6 multiple stream 490 Mb/s1233 Tbm/s IPv6 single stream via NY 350 Mb/s5154 Tbm/s IPv6 multiple stream via NY 400 Mb/s5894 Tbm/s

12. Academic and Research Network of Slovenia IPv6 LSR entries in Internet2 competition single stream on first path - 1215 Tbm/s –accepted as a new Internet2 record (04 Oct 2002) single and multiple stream on a longer path (5154/5894 Tbm/s) –submitted on 09 Oct 2002, but not accepted yet

13. Academic and Research Network of Slovenia IPv6 LSR conclusion IPv6 forwarding in GÉANT comparable with IPv4 no problems observed on double-stacked Juniper routers much more to be done to deploy IPv6 in the near future (dynamic routing, management etc)
