Anyone knows of/used TCP::rtt (smooth TCP round trip time)?
Hi,
I was wondering if anyone has any experience with or knows of the algorithm used with the TCP::rtt metric which is supposed to return the "smoothed round-trip time estimate for a TCP connection"?
I've done some experimentation and sometimes the rtt is zero - which I assume means that there hasn't been enough data for the estimate? It is also difficult to figure out how the smoothing algorithm works and how far back in time does the estimate go. It also seems to be less accurate in small latency situations.
Any help on this would be greatly appreciated!
