Infrastructure?...That’s easy!

RIPE ATLAS: 11k++ probes (02/2020)

Results

DPs: 80K destinations CPs: BGP dumps every 2h

Dataset

6 VPs in PEERING ~ 10/20 days 2 Additional VPs ~ 8 months Currently ~ not running ~ undisclosed (soon)

Conclusions

Results

  • Few lies, but not zero!
  • Some exceptions with high MM rate
  • Look closer at the remaining mismatches

Infrastructure

  • Need for co-located VPs
  • Peering Testbed (few full RIBs)
  • Look for more co-located VPs
