Bottlenecks
Identification
- Traceroute
- from/to multiple sites can identify common path segments in the maps
- Can see onset of losses with traceping
- Pathchar can identify bottlenecks
Then need to work on:
- avoiding bottlenecks (new peering)
- getting bottleneck owners to improve
- this is difficult, lots of potential bottlenecks, bottlenecks move, not under our control
