Hi I was not able to get your example to work, all local traffic would stop, but using the example in the link I have in my first email I was able to get A+ https://www.waveform.com/tools/bufferbloat?test-id=dbde0dcc-3ba1-4d07-8732-9... Connecting via WIFI and doing that test gave me a D, so I'll need to do some work on the WIFI here at work. Mike On 4/3/2024 6:41 am, Jason Hecker via Public wrote:
I have been using CAKE lately. For a 100Mbit/100Mbit fibre link this is the setting that gets an A+ onhttps://www.waveform.com/tools/bufferbloat with jitter under 5ms each way. I had to do repeated tests until I arrived at using RTT=150ms as the magic number. Another site with a 200/200 link the RTT is 175.
I have never used queue trees in my life, simple queues have always sufficed. I was a big fan of PCQ before CAKE.
/queue type add cake-bandwidth=100.0Mbps cake-mpu=84 cake-nat=yes cake-overhead=38 cake-overhead-scheme=ethernet cake-rtt=150ms kind=cake name=CAKEMOD
/queue simple add name=MainQueue2 queue=CAKEMOD/CAKEMOD target=192.168.0.0/24
This modified CAKE is used on both up and download as it's a symmetric link.
For my home link 1000/50 FTTP NBN I use different queue settings for up and down.
/queue type add cake-bandwidth=50.0Mbps cake-mpu=84 cake-nat=yes cake-overhead=38 \ cake-overhead-scheme=ethernet kind=cake name=CAKENBNUP add cake-bandwidth=1000.0Mbps cake-mpu=84 cake-nat=yes cake-overhead=38 \ cake-overhead-scheme=ethernet cake-rtt=200ms kind=cake name=CAKENBNDOWN**
I have set the bandwidth in CAKE itself as it actually worked out well in spite of the warning in red:
# CAKE type with bandwidth setting detected, configure traffic limits within queue itself
I did not set the limit in the main simple queue. As it's the only item in this queue I think it's fine to set the limit in CAKE itself. If I was doing parent/child hierarchies it'd be different.
I am using CAKE on 4011 and 5009 routers that have plenty of beefcake CPUwise. The ol' hEX might have an issue.
Don't forget to keep in mind the different ethernet bus arrangements if you have switching enabled or disabled.
