I'm not buffering. Switches have packet buffers. I'm seeing switch buffers getting overrun by what appears to be Netflix traffic coming in at rates faster than the subscribers throttled speeds.

I'm not talking error retries on the line. I'm talking like two to three times in excess of what the customers CPE device can handle. I'm observing massive buffer overruns in some of our switches that appear to be directly related to this. And I can't figure out what possible good purpose Netflix would have for attempting to do this.Pardon my ignorance of WISP-specific bits here, but how are they supposed to know to back off on their bitrate ramp-up if you keep buffering rather than dropping packets when the TX rate exceeds the customer's service rate? Or what am I missing?Curious if anyone else has seen it?-- Hugo hugo () slabnet com: email, xmpp/jabber PGP fingerprint (B178313E): CF18 15FA 9FE4 0CD1 2319 1D77 9AB1 0FFD B178 313E (also on Signal)
