Codel on Cerowrt-3.3.6-2
A preliminary test release of CeroWrt is now available that has support for Kathie Nichols' and Van Jacobson's new AQM, codel, and Eric Dumazet's fq_codel.
A test release of CeroWrt is now available that has support for Kathie Nichols' and Van Jacobson's new AQM, Codel , and Eric Dumazet's new fair queuing implementation on top of that, fq_codel.
fq_codel is enabled on all interfaces by default. It is vastly simpler than what we were using before (sfqred) and draws upon and improves on the same body of ideas (head drop, fq, timestamping) but now tied to Kathie and Van's blinding insights as to a good drop strategy, and Eric's successor ideas as towards head of queue behavior and cache line optimizations.
There is a simple_qos.sh script that can be set to your uplink and downlink speeds, but no uci interface for it as yet, nor gui. (help on finishing aqm-scripts and the luci interface gladly accepted)
To see all the chocolately goodness of what fq_codel can do to wired and wireless latency, it would be good for more to play with it.
Benchmarks have been very good thus far, and more benchmarks and analysis are highly desired.
This release suffers from an unrelated bug ( #379 ) and should NOT be installed as your main router. I would love to beat this bug because it's the only prio 1 remaining but thus far, no luck. Under lighter loads CeroWrt appears to work just fine, but that's for me. YMMV.
