The examples and documentation that I've found for RouterOS quality of service and queuing, all seem to need a known bandwidth to be set either as the maximum for a given traffic class, or the max available on the interface. Are there any mechanisms that adapt to the rate that's actually available at the time? In particular I was thinking of LTE applications where the available bandwidth can vary from time to time. For example let's say I wanted to prioritise SIP on an LTE uplink, I don't want to throttle other bandwidth to allow enough space for SIP, instead I'd want the device to preferentially transmit my priority traffic, either by choosing it's queue preferentially if that's how it works, or by high priority packets "jumping the queue" so to speak.
