Hi there, I am attempting to run some experiments with DCTCP using mininet (so this is all user-level emulation -- my switch is a linux namespace using OVS). My question is on how to apply DCTCP's AQM. DCTCP's AQM just marks all packets with CE if they are received when the queue is over a threshold value of K and otherwise does not mark CE. The DCTCP papers I have seen suggest that RED can be used to achieve this: set probability to 1, burst to 1, and min and max to the same value.
However, tc-red, in accordance with this paper, does not allow burst to be significantly below the minimum threshold value, so I am unable to set the parameters I would like -- in particular to set burst to 1 -- without monkey-patching tc. Is there a way to achieve this simple threshold-ECN marking AQM with tc, or another approach?
