Most of the "bufferbloat" aftermarket fixes work by assuming the ISP connection has a fixed data capacity. You are the first person I've found on mikrotik fiddling with their fq_codel implementation. Can CAKE not identify periodic flows and then observe that the time gaps between those periodic flows expand and so there is bufferbloat? How do you, from cake's intermediate position in the network figure out whether any gaps in the packet sequence are caused by congestion or simply be the remote sender not having sent something at that exact point in time?

The default queuing discipline in Linux employs three parallel bottles of varying sizes; one for bulk traffic, one for high-priority traffic, and one for everything else ("normal" traffic). Do you plan to implement proper SQM in the future such as Cake or fq_codel to help address traffic between mesh nodes as well as bufferbloat on the WAN port? CAKE helps a lot > when running on ingress, but it can't come close to running on both > ends. Bufferbloat is high latency (or lag) that occurs when there’s other traffic on your network. 19 was released on Monday, 22 October.

I use a PCQ queue tree to keep my bufferbloat under load between 20-100ms compared to 300-1000ms without it. A few years ago I used fq_codel at a campground to shape a 0. net. Cake: the latest in sqm (QoS) schedulers Today I finally had the opportunity to try out Cake , the new replacement for the combination of HTB+fq_codel that the bufferbloat project developed as part of CeroWRT's sqm-scripts package.

Summary: This release adds: the CAKE network queue management to fight bufferbloat, it is designed to fight intended to squeeze the most bandwidth and latency out of even the slowest ISP links and routers; support for guaranteeing minimum I/O latency targets for cgroups; experimental support for the future Wi-Fi 6 (802. The latency (and jitter) caused by bufferbloat has been a solved problem for almost five years: fq_codel, and the newer cake qdisc's are are in the Linux kernel, and people's home routers now could install LEDE/OpenWrt (https://lede-project. org). Re: help with bufferbloat, fq_codel, codel and cake not working. Also, cake, as a deficit mode shaper, it is the opposite of how htb functions in terms of bursts. End-to-end congestion control methods, such as TCP and QUIC, are the main ways of avoiding congestion on the Internet, and much research has gone into improving the latency performance of TCP. 4. [Posted April 25, 2022 by corbet] Dave Täht has put together a summary of the state of fair queuing and the fight against bufferbloat in general. Just get it as part of the SQM tools in OpenWRT and enable it. A+ bufferbloat score even with a dozen people maxing out the connection.
