Barry,
: Eth0 is connected to a private network which has on it a Media Server
: streaming rtsp files Eth1 is a wireless card on an ad-hoc network with
: a laptop, a pda, and a desktop.
Understood.
: The idea is then to imitate different QoS levels to the different
: devices, the idea being that the pda shouldn't need as much bw as the
: desktop etc. So the three devices get dhcp leases dependant on their
: mac address, and then their ip address is used to identify them and
: (hopefully) tc will then allow me to create sfqs for each device.
Understood.
: I have tested the devices without any shaping, and also with shaping of
: all rtsp/mms protocol based traffic to the 50kb class. This works and
: has been confirmed by the stats on the media client, it can be quite
: clearly seen any way the video starts to jump and stutter.
OK.
: However I have been unable to get the shaping to only occur on one
: device, maybe the laptop for example whose address is 10.1.1.10
I don't really understand what you mean here.
Have you tried creating separate classes for each device?
sfq doesn't do any shaping
htb (classes) perform shaping
So, here's a fractured/partial tcng config:
#define MY_PDA 10.1.1.8
#define MY_LAPTOP 10.1.1.10
class ( <$video> ) if tcp_sport == PORT_RTSP && ip_dst == MY_LAPTOP ;
class ( <$laptop> ) if ip_dst == MY_LAPTOP ;
class ( <$pda>) if ip_dst == MY_PDA ;
class ( <$other>) if 1 ;
htb() {
class ( rate 3500kbps, ceil 3500kbps ) {
$video = class ( rate 50kbps, ceil 50kbps ) { sfq; } ;
$laptop = class ( rate 50kbps, ceil 1500kbps ) { sfq; } ;
$pda = class ( rate 50kbps, ceil 50kbps ) { sfq; } ;
$other = class ( rate 200kbps, ceil 3500kbps ) { sfq; } ;
}
}
I can't tell if this does what you'd like, but maybe it does.
Good luck,
-Martin
