Re: [Astlinux-devel] traffic-shaper: fq_codel (Fair Queueing CoDel)

Hi Lonnie

Thanks again for all your work.

So with htb you shape default traffic to the Line Rate (or line CIR) minus Required Voice Bandwidth (e.g. 100K G.711 x max sessions). But with hfsc, you set it to the Line Rate (or line CIR) and default traffic has access to the full Line Rate while there is no voice traffic. Is this correct?

Hi Devs,

A quick note, as of r8362, the "traffic-shaper" plugin, now uses the fq_codel (Fair Queueing CoDel) for both 'htb' and 'hfsc' types.

In the past, many of us have found the 'hfsc' shaper not as good as expected.  With the addition of fq_codel the 'hfsc' shaper type works much better than before in my limited testing.

Personally I have a 50/10 Mbps cable connection, so I set the Uplink Speed to 10000 and disabled any ingress shaping, ex.

Testing this sort of shaping stuff is difficult to do, but so far is working well for me.

Everyone reading this should do some tests of their own.
