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

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.
Thanks!
