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

26. 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!
