Thanks for the long, good and detailed answer. Your observations regarding how samples and compression works explains why I'm seeng these large losses in the aggregated graphs. I do follow and agree on your reasoning why this is a good thing.
This is a side track, but I'm not in complete agreement regarding that "all loss is evil". Losses due to transmission failures (CRC errors etc) are bad. Losses due to congestions are a good thing, else you end up in a bufferbloat scenario with large latencies. (I'm a network engineer, one of the DSL routers had a buffer so large that we had 30 seconds delay on ADSL, which is not a good user experience). In my scenario I do know that there is a ICMP rate limiter in the DSL router, and at the BRAS. Each with different points where they kick in. And rather lots of devices on this access producing ICMP. My user experience is a lot better than what the graphs may indicate. :) And I also test a lot pre production firmwares, different routers, sometimes I swap out the ethernet cable for WLAN bridge or PLC bridge. Sometimes we test differend profiles on the DSL link. So, yes things move around a lot on my setup. -Erik _______________________________________________ smokeping-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/smokeping-users
