Update on Two-UDL Experiment and Satellite Link Utilization Status

This brief update outlines the status of the Two-UDL experiment, highlighting that the results have failed due to issues with MAC learning and Ethernet frame forwarding at the Cisco bridge. The fallback plan includes SFC transmission at 128Kbps for routing protocols and 1Mbps/0.5Kbps from partner transmission. The report also addresses failures in the JSAT and SONY feeds due to unimplemented configurations and a lack of technical support. Future steps involve completing the JSAT codec, testing at 13Mbps, and ensuring attention to ongoing classes during this migration and configuration process.

  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
