Re: [Bloat] Congestion control with FQ-Codel/Cake with Multicast?

Hi Linus, One correction on that last message: After sending and re-reading I belatedly realized it's completely viable to snoop SDP over SAP if you wanted to. So I guess it's not a non-starter if you don't care about solving other kinds of multicast traffic in addition to the ones in that can a

Hi Linus, I did do some multicast tests with an OpenWRT that was recent when I did them in about 2019-2020 IIRC. I did not look at any FQ/CAKE while doing it. I wouldn't call FQ a viable, fair congestion control for this, though I do expect it would isolate the damage to flows that share the que

Hi David, That’s an interesting point, and I think you’re right that packet arrival is poorly modeled as a Poisson process, because in practice packet transmissions are very rarely unrelated to other packet transmissions. But now you’ve got me wondering what the right approach is. Do you have
