In one embodiment, a plurality of connections couple to a plurality of service providers (SPs) that each provide services at a cost. The cost of the services of each SP is determined according to a tiered pricing structure that includes one or more tiers. Each tier correlates a particular amount of data transferred with the SP to a particular cost. A data collector collects measurement data that indicates an amount of data transferred with each SP. A processor selects a target tier in the tiered pricing structure of each SP based on the measurement data. The processor also generates a momentary target utilization rate (MTUR) for each SP based on the target tier for the SP and the measurement data. The processor then distributes utilization of services among the SPs based on the MTUR and tiered pricing structure of each SP to minimize the cost of the services provided by the SPs.
