Abstract:
Method for achieving fair share between point-to-point connections and point to-multipoint connections in a switch, comprising at least one buffer for each physical link and at least one buffer for point-to-multipoint connections, the method comprising the steps of:storing the cells belonging to point-to-point connections in a queue structure according to the physical link on which they are transmitted; storing the cells belonging to point-to-multipoint connections in another queue for point-to-multipoint connections; selecting a physical link on which a point-to-point cell should be transmitted; determining if the first cell in the point-to-multipoint queue should be transmitted on the physical link selected; if both a point-to-point cell and a point-to-multipoint cell should be transmitted on the physical link selected, determining which one of the point-to-point cell and the point-to-multipoint cell was first stored in the queue structure and transmitting this cell to an output queue.
