ABSTRACT:
A network device for dynamically allocating memory locations to plurality of queues. The network device determines an amount of memory buffers that is associated with a port and assigns a fixed allocation of memory buffers to each of a plurality of queues associated with the port. The network device also shares remaining memory buffers among the plurality of queues, wherein the remaining memory buffers are used by at least one of the plurality of queues after the fixed allocation of memory buffers assigned to the queue is used by the queue. The network device further sets a limit threshold for each of the plurality of queues. The limit threshold determines how much of the remaining memory buffer may be used by each of the plurality of queues. When one of the limit threshold is reached for one of the plurality of queues or all of the remaining buffers are used, a request by the one of the plurality of queues is denied.
