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

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
