Should be documented in the man page. Some comments are due anyway: > > add 65001 queue 13 out iptos lowdelay iplen 0-250 xmit IF_EXT The 'iptos lowdelay' short packets should cover protocols like NTP or VoIP. > > add 65002 queue 13 out proto udp src-port 12334 xmit IF_EXT Port 12334 is my Skype magic port. > > add 65003 queue 13 out proto udp iplen 0-250 xmit IF_EXT Remaining short UPD packets, like DNS query/replies etc. > > add 65004 queue 12 out proto udp xmit IF_EXT > > add 65005 queue 12 out proto icmp xmit IF_EXT I like pings to be responsive. > > add 65006 queue 12 out proto tcp tcpflags ack iplen 0-80 xmit IF_EXT ACK-only packets should have priority, otherwise traffic in reverse direction is unnecessarily slowed down by traffic in forward direction (and the other way around). > > add 65007 queue 11 out proto tcp iplen 0-300 xmit IF_EXT Interactive typing (remote emacs, console, ...) > > add 65008 queue 11 out proto tcp src-port 80,88 xmit IF_EXT Replies from my web server. > > add 65009 queue 10 out proto tcp dst-port rsync xmit IF_EXT Backup has the lowest priority. > Just one question - you're saying that it is possible to shape /delay, > drop etc./ the packets so quickly so that when a pipe is fully utilized > someone hits a queue with a higher weight /for example port 80 would be > prioritized over p2p traffic/ it would be like as if the pipe was not used > at all? So it appears to me. Running Skype along with reading mail and running a nightly backup works fine.
