Hi Genis, I would like you to validate whether the options of adding headroom per CoS work for you.
IMO, adding headroom per CoS makes more sense since CoS defines a specific flow and the application might be interested to modify headroom per flow. Since with your current proposal the same is possible but that would mean you need to create different pools per different types of flows.
