Presentation Transcript

  1. Operation TF

  2. まとめ • 発表の目的 • Operator TFの円滑な議事進行 • 議題、提案点その他 • 次のスライドを参照願います • 結論 • アナウンス • スケジュールや手法、役割分担など具体的な実行計画を伴う合意

  3. Agenda • UDL Operation • UDL 13Mbps bandwidth extension • IPv4 Routing on UDL • Other Routing Issues • New network design in SFC • Security

  4. UDL Operation

  5. Topics • Report • UDL13Mbps extension and UDstation installation done • Keio establish maintenance contracet with UDcast for UDstation and UDbox • Backup UDstation and UDboxes will arrive soon • Backup UDStation box • Coming Soon • TBD Later • MTU 1500 on UDL • MTU 1452 on UDL should be legacy (SONY Feed problem) • TBD Later • Issues on UDstation 13Mbps Performance • Configuration is 13Mbps but actual output by MRTG is around 10Mbps • TBD Later • IPv4 routing on UDL • Install Private IPv4 for routing on the UDL (schedule and design) • TBD Later

  6. Backup UDstation and UDbox • Expected arrival date • Direction of operation • Expected topology including backup UDstation

  7. MTU 1500 on UDL • Current status • 1500 on sfc-udl-feed and ITB • ospf6dではipv6 ospf6 mtu 1452 • 1452 on others • OSPFv2 with ITB is okay • OSPFv3 with all uses if mtu 1452 definition in ospf6d.conf • AI3 Meeting後にOperator Meetingを開催して変更をします。 • 各サイトのRRにて、UDL I/FのMTUを1500に変更します。 • スケジュール未定 • TSペイロード長を考慮したMTUを設定

  8. Issues on UDStation 13Mbps Performance

  9. UDStation 13Mbps Performance • TCP tests on UDL: • Multiple wget sessions on SFC RO2: • web server is sfc-cpu, output is /dev/null • MTU is 1500 • Output is around 10Mbps (less than smartbit results)

  10. Comparing the Results iperf TCP results: Around 11Mbps Wget results: Around 10Mbps MRTG Sfc-udl-feed:bge1

  11. Testing direction and announcement • Do more tests to confirm • iperf vs wget • Smartbit UDP vs iperf UDP • If wget or iperf is less than Smartbit: • Why? • Contact UDcast? • Use tcpdump, then gets more accurate number • UDL maybe blocked for testing

  12. IPv4 routing on UDL

  13. Routing for AIT and ITB • BDL bandwidth changes due to UDL 13Mbps migration • SFC-ITB and SFC-AIT are 128kbps • OSPFv2 is running on UDL • Neighbor: ITB, AIT should be neighbor, too. • Prefer routes via UDL than BDL

  14. Install Private IPv4 for routing on the UDL • Background • Discussion • Design • Schedule

  15. Other Routing Issues

  16. SFC installed a Cisco Router • SFC installed Cisco with 5 I/Fs • Show current status and changes made in the routing /topology

  17. Connection to WIDE Fujisawa NOC BGP MAIN 202.249.26.115 2001:d30:101:4::3 sfc-c7200 gi0/1 vlan 200 gi0/2 vlan 140 gi0/3 vlan 49 fa5/0 vlan 31 1G-SX Tagged VLAN: 31,49,140 ? gi0/2 foundry1 S3/23 fa0/1 WIDE switch 100-TX Tagged VLAN: 31,49,140 AI3 switch ? ? fa0/29 202.249.26.116 2001:d30:101:4::4 202.249.26.114 2001:d30:101:4::2 202.249.26.113 2001:d30:101:4::1 Cisco 12000 gsr1. fujisawa sfc-gate BGP backup BGP backup BGP MAIN

  18. M6bone • Current status: • Tunnel with RENATER using sfc-c7200-gate • Failure on advertising AI3 prefix to RENATER • Trouble shooting is on-going • Next: • Move c7200 to AI3 rack • BGP peers Fujisawa cisco 12000 • Push APAN-JP and TEIN2 to activate PIM-SM and MBGP

  19. FreeBSD-specific Issues • Routing socket issue FreeBSD 4.10 ~ • Kernel doesn’t inform all route deletes if too many deletes in a small period • Ex: route flush • Result: Zebra doesn’t reinstall all routes deleted by, e.g., route flush • Husni patched zebra code • Already run on some routers in AI3 • Should let others know

  20. Multicast Routing: XORP Issues • SOI Asia is using XORP 1.1 • Some bugs. E.g.: doesn’t update MRIB if there are changes in kernel • Should upgrade to XORP 1.3 + patches • Unpatched XORP 1.3 has next-hop interface problem in MRIB

  21. AI3 SFC NetworkMiddle-term Design

  22. Todos for preparation • Show the final topology • Show the intermediate topology for the near future (Change topology with current cisco) and discuss routing and addressing

  23. C-band BDLs sfc-udbox sfc-udbox2 sfc- bridge Sfc-udl-feed sfc-ro1 -gate sfc-ro2 -gate sfc-gate2 sfc-gate WIDE APAN NSPIXP6 NAIST

  24. Generic Requirement • Less operational cost and more stability • Integrate some PC routers to Cisco routers • Distinguish challenge and stable operation (ex. sfc-udl-feed) • Capability of fiber optic connections in backbone • Redundancy against hardware troubles • Backup for core routers • Backup for UDstation • Interoperability between challenge and stabile operation IPv6 deployment

  25. Less operational cost and more stability • Integrate some PC routers to Cisco routers • Decrease the risk for hardware trouble • Trials with PC router like sfc-udl-feedv.s backup using Cisco router • Need to clear out the minimum interoperability between challenge and stable operation

  26. Capability of fiber optic connections in backbone • For the future operation, routers and switches connecting to the backbone may need gigabit Ethernet interface

  27. Redundancy against hardware troubles • Duplicate some important routing entities • sfc-gate • sfc-udl-feed • sfc-sat • sfc-udstation

  28. IPv6 deployment • Server upgrade • WEB Cache • DNS • SOI-Asia applications? • Routing in the UDL network • IPv6 for all SOI-Asia partners • Private IPv4 for a part of partners • BDL partners • IPv6-only connection for new RO sites

  29. Security

  30. Unsrat Open Proxy • Show and confirm the ai3 security policy
