摘要
In a method and multi-queue packet scheduling system for managing network packet traffic, each of a plurality of output buffer queues is assigned with a reserved weight in bandwidth sharing of an output link, is associated with a respective service class, and may be optionally assigned with a maximum rate to constrain packet transmission therethrough. The output buffer queues are adapted for enqueueing incoming packets therein according to associated service classes of the incoming packets. A shared bandwidth rate calculator determines in real-time shared bandwidth rates of maximum-rate constrained backlogged output buffer queues with reference to the reserved weights and such that the shared bandwidth rates do not exceed the assigned maximum rates. A packet scheduler transmits outgoing packets from the backlogged output buffer queues in accordance with a schedule that is based on the shared bandwidth rates determined by the shared bandwidth rate calculator.
