1. A method comprising: determining, by a device, that a subset of scheduling nodes is being backpressured; setting, by the device and after determining that the subset of the scheduling nodes is being backpressured, a first value to a maximum of a second value or a third value associated with the subset of the scheduling nodes; setting, by the device and after determining that the subset of the scheduling nodes is being backpressured, the second value to match a fourth value associated with the subset of the scheduling nodes; and replenishing, by the device and based on at least one of the first value or the second value, credits associated with the subset of the scheduling nodes.
