Experiments
Analyzed secondary paths between between 20 source/destination AS pairs
- Inject and monitor BGP faults
- Survey providers to determine policies behind paths
To provide intuition, we will focus on faults injected into three ISPs at Mae-West
- Observed faults via fourth ISP (in Japan)
- Three ISPs roughly map onto tier1, tier2, tier3 providers
- Results from these three ISPs representative of all data
