Abstract:
1. A network device for dynamically allocating memory locations to a plurality of queues, the network device comprising: assigning means for assigning respective portions of a temporary memory buffer to each of a plurality of ports and assigning respective portions of a shared memory buffer to each of the plurality of ports; and allocating means for allocating respective fixed allocations of the respective portions of the temporary memory buffer assigned to each of the plurality of ports to each of the plurality of queues associated with each port and allocating respective fixed allocations of the respective portions of the shared memory buffer assigned to each of the plurality of ports to each of the plurality of queues associated with each port, wherein after each queue has accumulated a predefined amount of data for a respective class of service in the temporary memory buffer, the data for the respective class of service is transmitted from the temporary memory buffer to the shared memory buffer based on at least: such that the allocating means reduces a shared memory buffer access bandwidth of the shared memory buffer by a predefined amount that is less than a processing bandwidth of a system clock.
