I want to look into policing for enforcing the ceiling per element, but =
to my disappointment I cannot get it working. whatever I use for values, =
nothing changes in the measured trhoughput I I don't know why.

If I use the stuff below I expect that the throughput for host =
asterix.askesis.nl will be 10Bps. Which is not the case. But whatever =
values I use nothing changes in the throughtput. It appears that tat the =
ingress rules is ignored. Any ideas?


  ingress
  {
        /*
        TCNG manual p. 39
        SLB(cbs,cir [,mpu])
            cbs: commited burst size in bytes (size of bucket)
            cir: commited information rate in bps (rate of entering =
bucket)
            mpu: minimum policed unit in bytes (size of bucket =
in/decrement ?)
        */
        $network =3D SLB( cbs 10B, cir 10 Bps);

        /*
        SLB_ok, if true pass the packet
        SLB_else_drop, if true drop the packet
        */
class(<>) if ip_src =3D=3D host "asterix.askesis.nl"
&& =
SLB_else_drop($network);
  }

You don't need policing for the forcing a ceil, htb can this too.

Do you know how slow 10Bps is ?????   Use some real values like 10KBps or s=
o.

Do you want to shape outgoing traffic or incoming traffic?  Ingress is for=

incoming traffic, htb is outgoing traffic.
You can use htb for incoming traffic if you use the imq device or if you ca=
n=20
shape on a router, you can shape on both interfaces.
