ABSTRACT:
A method is provided for temporarily storing data packets, in which incoming data packets (D1, D2, D3) are distributed to and temporarily stored in two or more logic queues (QU1, QU2) on the basis of data (P1, P2) contained in the incoming data packets (D1, D2, D3), and in which all of the logic queues (QU1, QU2) share a common buffer memory (MEM) having locations that are dynamically allocated to the logic queues (QU1, QU2) only when required. The method features the steps of rejecting individual data packets (D1, D2, D3) if proper treatment is not ensured for all data packets, determining queue length data on the lengths of the logic queues (QU1, QU2), determining queue allocation data on which of the logic queue (QU1, QU2) an incoming data packet (D1, D2, D3) will be allocated, and selecting the incoming data packets (D1, D2, D3) to be rejected on the basis of the queue length data and the queue allocation data.
