BW guarantees in the forwarding plane are implemented with a queuing infrastructure and a scheduler that allocates BW to those queues. If you differentiate the traffic correctly at every node and map it to the correct queue, the scheduler will guarantee a minimum BW allocation to the queue regardless of the offered load to other queues.
