PingER - Surveyor Complementarity
Surveyor has one way measurements, PingER only round-trip
Surveyor dedicated platforms & strong central management
- experience with PingER shows this has benefits.
PingER more parsimonious (bandwidth, disk space)
- better for poor connectivity sites - e.g. Russia, China
- but necessarily less accurate especially at small (hourly time resolution on low loss links).
PingER good for looking at long term trends & grouping where statistics are less a problem.
