Methods and computing systems for allocating an information rate to a particular traffic type of a plurality of traffic types of egress traffic is described. A state of the particular traffic type for a particular time slot of a current time period is determined. This includes determining the information rate such that a loss probability threshold is not exceeded, based on historical data of the particular traffic type. The historical data includes a plurality of observed throughput rates of the particular traffic type during a plurality of previous time periods at which the particular traffic type experienced the state of the particular traffic type. The information rate (e.g., a committed information rate) is allocated to the particular traffic type for the particular time slot.
