Content

  • DeltaINT-O
    • DeltaINT with delta omission
  • DeltaINT-E
    • DeltaINT with delta encoding
  • In DeltaINT-O/E
    • Software experiments
      • HPCC-DINT
        • Source code of congestion control
      • INTPath-DINT
        • Source code of gray failure detection
      • Mininet-DINT
        • Source code of path tracing, latency measurement, and fine-grained monitoring
    • Hardware experiment
      • Tofino
        • P4 code of four families of in-band network telemetry on Tofino switch
    • NOTE: as the only difference between DeltaINT-O and DeltaINT-E is on metadata insert for negligible delta (i.e., omission or encoding), while all other operations are the same (e.g., state load, delta calculation, and state update), we dump per-node device-internal states and calculates the bandwidth cost of DeltaINT-E by software simulation in software experiments
