State machine design for Bananapi R4

• High level design

  • Initial Setup:
    • User enables speed test by setting Enable_Speedtest=true
    • This is validated through cosa_ip_dml.c
    • Parameter is stored in TR-181
  • Test Execution:
    • User triggers test by setting Run=true
    • System checks Enable_Speedtest status
    • If enabled

      • • /usr/ccsp/tad/speedtest.sh # Launches with lowest priority

  • Download Phase:
    • speedtest-client initiates download
    • BBHM updates tracked in real-time:

      • pStats->TestBytesReceived += s_result;

      • pStats->TotalBytesReceived += s_result;

    • Timing parameters updated:
      • ROMTime (start)
      • TCPOpenRequestTime
      • BOMTime (begin of measurement)
  • Upload Phase:
    • Similar flow to download

      • pStats->TotalBytesSent += s_result;

  • Completion:
    • Final statistics stored in BBHM
    • All parameters accessible via TR-181
    • Run parameter set back to false

  • The entire process is managed by the Test and Diagnostics framework, with:

    • Real-time statistics collection
    • Proper error handling
    • Persistent storage of results
    • TR-181 parameter updates throughout the test
    TBD

• Low level design
