Abstract: A router requests a reservation for an egress port prior to dequeuing data from an ingress port data queue. A request is also made for the allocation of a buffer. After the reservation is received and a buffer is allocated, the data is copied the ingress port data queue to the buffer, and an identifier of the buffer is enqueued to an identifier queue of the egress port. After the identifier is dequeued, the data is copied from the buffer to an egress data queue of the egress port, and the buffer is released for reallocation. The buffer can be released prior to completion of the data being copied from the buffer. The queues associated with the egress port determine whether their depths equal or exceed a threshold associated with the respective egress queues. If one or more of the depths does equal or exceed the associated threshold, the granting of reservations for the egress port are postponed.
