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.
How big are your buffers (preferrably answer would be in milliseconds)? What access speeds are you providing? It's standard behavior for network traffic to sometimes be at higher speeds than the customer access speeds, the sender only knows about congestion if there is an increase in RTT or if there is packet loss (or in case of ECN, EC=1 flag), and the only way to find out is to probe (=run faster than customer access speed). -- Mikael Abrahamsson email: swmike@swm.pp.se
