Dear all, I am starting with Linux Qos mechanism. I believe that for my needs the two Qdiscs: - PRIO - pfifo_fast are enough. In fact I am trying to set up a simple Linux-box 1Lan-1Wan able to distinguish and give priority to VoIP traffic against IP BE traffic on WAN interface. Yet I cannot find any examples concerning these Qdisc (for pfifo_fast I cannot even find manpages) . May you help me ? Thanks in advance for your support.
