  1. Brief Update fromOperation-TF

  2. Topics • Two-UDL Experiment • UDL 13Mbps Status • Satellite Link Utilization

  3. Two-UDL Experiment

  4. 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

  7. 13Mbps Status

  8. 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

  9. 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

  10. Padding and Section Packing Padding Section Packing

  11. 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

  12. 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
