VERFAHREN ZUR ERFASSUNG VON DATENSTAUS AM EINGANG EINES ATM-SCHALTERS MIT VERTEILTER STRUKTUR UND SPEICHERUNG AM EINGANG

摘要

A process for detecting upstream congestion within an ATM switch. The switch includes several junctions linked together by a cross-connector. In each input junction, the number of incoming cells bound for a same specified output port of a junction are counted. Results of the count supplied by the input junctions are transferred to the output port. Results of the counts in the output junction are aggregated and a congestion is declared in the output port if the aggregate number of cells is greater than a specified threshold value.
