Maybe I don't fully understand the fundamentals, but there is a question.
There is an option "bandwidth contract" on IAPs.
On what step does it apply?
1. The IAP takes the client traffic normally (the only prioritization on this step is Fair Access and Preferred Access), then cuts it's and sends it further with limited bandwidth.
2. Or does the IAP somehow cut the traffic before the full receiving?
The question is about - what is the goal to restrict the bandwidth?
Is it for proper utilization of internet connection, or is it for proper utilization of the IAP's resources or/and RF?
