  1. TEIN2 NOC Updates Xing Li 2007.5.15

  2. Outline • General Operation Updates • Current Status of Advanced Service • Traffic Analysis between TEIN2 and GEANT2 • BGP Peering Statistics • Thoughts

  3. General Operation Updates(2007.2 – 2007.4) • TEIN2 Topology • Major Operation Issues • Trouble Ticket Statistics • Link Availability • Link Utilization

  4. TEIN2 Topology

  5. Major Operation Issues • Deactivated STM-4 circuit between Beijing and Copenhagen • Cooperated with TEIN2-JP NOC on cutover of new HK-JP STM-4 circuit • Cooperated with TEIN2-JP NOC on cutover of new SG-JP STM-4 circuit • Cooperating with AARNet NOC on acceptance of 2 new SMW4 STM-1 circuits between Singapore and Frankfurt • Cooperated with MYREN, DANTE and circuit provider on SG-MY link flapping problem

  6. Major Operation Issues(continued) • Upgraded JUNOS on BJ/HK/SG POP routers • Activated MPLS over TEIN2 backbone • Cooperated with SingAREN and APAN-JP NOC on backup transit service from SingAREN for traffic between TEIN2 and APAN-JP • Increased the access bandwidth between CERNET and TEIN2 backbone from 622Mbps to 1Gbps

  7. Major Operation Issues(continued) • Cooperated with DANTE and TEIN2 NRENs on evaluation of possible contribution from TEIN2 backbone for PRAGMA project • Cooperatd with TEIN2 NRENs and partners on IPv4/v6 multicast routing issues • Deployed a new measure server in SG POP

  8. Trouble Ticket Statistics

  9. Link Availability(w/o maintenance)

  10. Link Utilization(average)

  11. Link Utilization(maximal)

  12. Current Status of Advanced Service

  13. Traffic Analysis between TEIN2 and GEANT2 • 3 links between TEIN2 and GEANT2 • BJ-EU_2 (STM-16) • SG-EU_1 (STM-4) • SG-EU_2 (STM-4) • Statistics based on cflow • Sample rate: 100:1 • Time scale • From 2007. 2.1 to 2007.04.30

  14. Packet Length(BJ-EU_2)

  15. Packet Length(SG-EU_1/2)

  16. AS Top 10(BJ-EU_2) AS Description: 4538 CERNET 786 JANET 680 DFN 1103 SURFNET-NL 224 UNINETT 1653 SUNET 12816 MWN 553 BELWUE 2107 ARNES-NET 9916 NCTU-TW

  19. Protocol Top 10(SG-EU_1/2)

  20. Service Top 10(BJ-EU_2) Traffic Distribution: 86.8% Unknown (P2P etc.) 11.7% WWW 0.7% Media Stream (RTSP) 0.3% FTP 0.2% DNS 0.1% E-Mail (SMTP)

  21. Service Top 10(SG-EU_1/2) Traffic Distribution: 80.1% Unknown (P2P etc.) 16.4% WWW 1.8% FTP 0.7% DNS 0.4% E-Mail (STMP) 0.2% Media Stream (RTSP)

  22. Address Block Top 10(BJ-EU_2)

  23. Address Block Top 10(SG-EU_1/2)

  24. BGP Peering Statistics(IPv4)

  25. BGP Peering Statistics(IPv6)

  26. Distributed Network Management

  27. Distributed Network Management

  28. Thoughts – towards TEIN3 • Layer 2 services. • Currently, TEIN2 backbone support MPLS • Network Measurement services. • Measurement servers are in all TEIN2 Pops support DVTS, iperf and multicast.

  29. Thanks!
