Re: Using RouterOS to QoS your network - 2020 Edition

TCP uses a three-way handshake to establish a reliable connection, why prioritize the ack traffic only?? We aren't trying to prioritize the handshake. The handshake is only 3 small packets to establish the TCP connection. Once you establish the connection and then start downloading at full speed, y...

Re: Using RouterOS to QoS your network - 2020 Edition

the congestion methods mentioned all seem to apply to TCP exclusively TCP and QUIC are stream protocols - as in you have a large amount of data and you will send multiple packets to transfer it. What the connection methods do is to drop some packets as a signal that the stream should slow down. So ...

@pcunite
No worries. I'll see if I can rerun the test graphs with the updated baseline when office reopens.

Re: Using RouterOS to QoS your network - 2020 Edition

I've done some testing with a closer server. Four cases considered: baseline, QOS2020, QOS2020-Optimised (my recommended changes), mikroCAKE (pseudo-CAKE implementation). Graphs of the bandwidth vs latency, and a latency distribution plot. All tests were Perth to Sydney, 30 seconds of baseline eithe...

Re: Using RouterOS to QoS your network - 2020 Edition

Wow, thank you for doing this. To remove any ambiguity, would you please post your queue config ( between code tags ) so I can study it? How well did my reference implementation do for you? I want to make sure that your config is not too specific to your needs as we do need something general that p...

Re: Using RouterOS to QoS your network - 2020 Edition

Did a pile of testing today with Flent measuring bufferbloat and performance. The final system that gave the best results (no increase in latency when limited to 90% of line bandwidth) is below. Set the two parent queues (UP and DOWN) to have a bucket-size of 0.005. This means that up to 5ms of toke...
