Abstract: A network device includes one or more dies, wherein each die, of the one or more dies includes one or more packet forwarding components and a switch fabric component. The switch fabric component of a particular die, of the one or more dies, may be connected to the one or more forwarding components of the particular die, and may be configured to provide a switching plane for the one or more packet forwarding components of the particular die. A first die, of the one or more dies, may be connected to the one or more packet forwarding components of a second die of the one or more dies, and may be configured to provide a switching plane for the one or more packet forwarding components of the second die.

Abstract: A network device may receive packets and may calculate, during a time interval, an arrival rate and a departure rate, of the packets, at one of multiple virtual output queues. The network device may calculate a current oversubscription factor based on the arrival rate and the departure rate, and may calculate a target oversubscription factor based on an average of previous oversubscription factors associated with the multiple virtual output queues. The network device may determine whether a difference exists between the target oversubscription factor and the current oversubscription factor and may calculate, when the difference exists, a scale factor based on the current oversubscription factor and the target oversubscription factor. The network device may calculate new scheduling weights based on prior scheduling weights and the scale factor, and may process packets received by the multiple virtual output queues based on the new scheduling weights.
