However, LibreQoS would fit best if you can build something in line with the design assumptions: https://libreqos.readthedocs.io/en/latest/docs/v2.0/design.html Specifically the part about putting it in between other routers and running a routing protocol with those. There are some good recommendations around suitable hardware and sizing/scaling too: https://libreqos.readthedocs.io/en/latest/docs/v2.0/requirements.html What kind of upstream bandwidth are you working with at the conference? I run the Mikrotik implementation of CAKE on a campsite. It really helps to get the most out of our asymmetrical gigabit coax line over there, no fiber available yet. So far, we got close to 500 devices on our outdoor Wi-Fi network with mostly good experiences, amazing. Before that, FQ_CoDel on PfSense worked well too, but the network wasn't as busy back then. I'd like to see CAKE on BSD some day.
