Brief Update fromOperation-TF
Topics
• Two-UDL Experiment
• UDL 13Mbps Status
• Satellite Link Utilization
Two-UDL Experiment
Two-UDL Experiment
• Result: Failed• Cisco bridge at BDL doesn’t forward Ethernet frames due
to MAC learning– MAC filtering at catalyst doesn’t help
• Fallback Plan as solution based on the current situation– SFC transmit 128Kbps
• Minimum just for routing protocol exchange
– Partner transmit 1Mbps/0.5Kbps• Feedback and commodity from partner site
– Design the routing so that traffic goes from SFC to partner via UDL, and from partner to SFC via BDL

13Mbps Status
UDL 13Mbps Status
• Status: Not completed yet– Failure on SFC SONY-Feed
• Suitable configuration not implemented
• No technical support
– Failure on JSAT SONY-Feed• Suitable configuration not implemented
• Availability unknown for technical support
– Failure on UDStation• JSAT codec not completed (Need padding for SONY-BOX)
• Modify to activate Pdding on UDStation
What is the cause of failure?
• JSAT codec is not completed on UDstation– UDstation uses packing– Padding is not available on SONY-Receiver, which causes packet
loss on SONY-Receiver when it receives traffic• What is padding / section packing?• What does UDStation (Section Packing) causes on SONY-RECV
(Padding-only)?
• Performance / Interoperability Problem?– When we send packet no to cause section packing…
• UDStation -> UDbox is Good• UDStation -> SONY-box is bad
Padding and Section Packing

Section Packing
Direction
• Wait for UDstation completing the JSAT codec
• Migrate to UDstation from SONY-FEED• Migrate to 13Mbps
– Feed: UDstaion– Receiver; SONY-BOX + UDbox
• Be careful not to disturb SOI-Asia Classes– Detail is in the next page
Todos & Schedule
• ~ Beginning of May– Complete JSAT codec on UDStation to migrate from SONY-Feed
• ~ Middle of May– Test 13Mbps configuration in IF Environment
• UDstation in mixed environment• SONY-Recv + UDBox
• ~ End of May– Fix the new bandwidth allocation for 13Mbps with Two-UDL
fallback plan– Finalize the instruction for 13Mbps migration
• Beginning of June ~– Ready for 13Mbps Migration in RF– Concern on SOI-Asia classes
