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
