A networked computing system employing a hybrid rate-limiting scheme, including one or more service provider device(s) (SPD) and one or more subscriber computing device(s) (SCD), and a data communications network facilitating data communications amongst the networked SPD and SCD devices. A SPD may apply the hybrid rate-limiting scheme to data communications provided to a SCD, based on both data bit count and data packet count information. The rate-limiting scheme may include a dual token bucket algorithm that facilitates rate-limiting PDUs in a data transfer queue utilizing one token bucket for metering data bits and another token bucket for metering data packets. The hybrid rate-limiting scheme may also employ a triple token bucket algorithm that includes one token bucket for metering data bits related to payload only data, a separate token bucket for metering data bits related to total PDU data, and another token bucket for metering data packets.
