Down to the QoS part....

[SomeWhereOverTheRainBow]

So I have built 2 new Openwrt Routers x86/64. I am down to selecting the proper QoS script. While I understand what "type" of QoS I want, I lack understanding on one concept - What is the difference between
simplest.qos:
Simplest possible configuration: HTB rate limiter with your qdisc attached.

and,

simplest_tbf.qos:
Simplest possible configuration (TBF): TBF rate limiter with your qdisc attached. TBF may give better performance than HTB on some architectures.

What I mean is, what architectures are they talking about when they say some are better with TBF and others are better with HTB?

 

[dave14305]

Architectures as in hardware family / chipset / target.

I use qosify to get CAKE with eBPF (kernel level) marking of DSCP for diffserv4.

here is the arch details.

Maybe if you feel like sharing some of your configuration details I would like to test them. I am using currently TBF testing it out. I only have experience with HTB.

Here is maybe a better image

What connection speed are your ups and downs? just asking so I can see how to best adjust those for testing,

nvm I see this part right here

for your Q setup script what are you using? Layer_cake or Piece of cake?

Since you’re on 21.03, the qosify package isn’t available to you. It comes with 22.03 or snapshots.

Not using sqm-scripts anymore. But when I did, I adapted ctinfo-4layercake.

You have many options on OpenWrt. Better to read a lot over there on their wiki and forum.

That is part of the problem. While the wiki leads to good knowledge, there is always a point where you hit a spot of vagueness, thus leading me to ask what specific Architectures is TBF preferred over HTB? A vague info on the wiki, and I haven't found any documentation on google or chatter in their forum.

 

[dave14305]

what specific Architectures is TBF preferred over HTB?

Probably old, slow MIPS routers from years ago. OpenWrt usually has sane defaults for most features. Try something and if it doesn’t work for you, change to something else.

I tested out the simplest with HTB, pretty cool results. I am currently moving to try out Cake with Piece_of_Cake. For cable service providers, would you bother adjusting the Advanced link layer options for MTU greater than 1500? I was under the impression adjustments here are not necessary with a cable ISP.
