I am not sure if this can be implemented but lets explain the situation.
We want to have different speeds depends of time in the day but we don’t want clients to be disconnected. Simply radius server will send request for only queue change without user disconnecting.
It would be cool to have time-of-day queues supported with a radius attribute. Unfortunately, I doubt it will get much traction with the boys at MT.
There are a few ways to cope with this. First, if the service is DHCP, setting a max time won’t cause any interuption to service. PPPoE is a different animal, but should still only be a few ms to reconnect.
Next, instead of passing queues directly from radius, pass an address list instead. Then queue by address list and have a script run to change those queues on an appropriate schedule.
IMO, PCQ and queue trees with address lists are the way to go. There should be a way to do it with simple queues, but I’ve not found a working solution yet.
Good luck!
