2. Introduce a “Virtual Latency Penalty / RTT Offset” Parameter for Individual WANs in DWB
This would be nice.
More generally, I’d want this latency “fudge factor” policy at the WAN level so it works for both outbound policies as well as DWB tunnels.
Personally, I’d bet that it implementing it as a “floor” instead of an offset would yield better and more predictable results. For example, if the floor is 100 ms, then the min RTT will always be 100 ms (even if the observed latency happens to be lower).
