Determining rate differential weighted fair output queue scheduling for a network device

A method comprising:

• determining, by a device, a current oversubscription factor based on a plurality of packets at one of a plurality of virtual output queues,
• wherein a virtual output queue, of the plurality of virtual output queues, is associated with one or more ports of the device;
• determining, by the device, a target oversubscription factor based on dividing a sum of previous oversubscription factors by a quantity of the plurality of virtual output queues;
• adjusting, by the device, scheduling weights for the plurality of virtual output queues when a difference exists between the target oversubscription factor and the current oversubscription factor;
• and
• performing, by the device, one or more actions based on the adjusted scheduling weights.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
• determine a current oversubscription factor based on an arrival rate and a departure rate of a plurality of packets at one of a plurality of virtual output queues,
• wherein the plurality of virtual output queues is associated with a plurality of ports of the network device;
• determine a target oversubscription factor based on dividing a sum of previous oversubscription factors by a quantity of the plurality of virtual output queues;
• adjust scheduling weights for the plurality of virtual output queues based on the current oversubscription factor;
• and
• perform one or more actions based on the adjusted scheduling weights.
