It's worse than I thought. I just watched this explainer video from = ExtremeNetworks: https://www.youtube.com/watch?v=3DowBrkFk9afM If I understand correctly, they want the AP to solve a hard = (bin-packing) problem, in real-time, with unclear rules for maximizing = client goals (should the VoIP packet go first?). And no mention of = airtime fairness or latency... Or am I missing something? Thanks. Rich=
