Verfahren und Vorrichtung zum Zwischenspeichern von Datenpaketen sowie Vermittlungsstelle mit einer solchen Vorrichtung

摘要

During overload conditions, the probability of loss of data packets (D4-D8) is approximately of equal magnitude in all queues (QU1, QU2). The loss probability cannot be graded. Data packets (D4-D8) are temporarily stored in a number of logical queues (QU1, QU2) which are dynamically allocated the storage locations of a common buffer memory (MEM). The unavoidable loss of data packets is systematised by selective discarding of data packets. A data packet (D6-D8) stored in a low-priority queue (QU2) is deleted when an incoming data packet (D1) is allocated to a higher-priority queue (QU1) and the total length of queues has exceeded a certain length. - A buffer with various adjustable access control or operating procedures can be implemented in a simple manner. - Fast solution, suitable for ATM.
