Abstract: A switching network includes an upper tier including a master switch and a lower tier including a plurality of lower tier entities. The master switch includes a plurality of ports each coupled to a respective one of the plurality of lower tier entities. Each of the plurality of ports includes a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Each of the plurality of ports also includes a receive interface that, responsive to receipt of data traffic from a particular lower tier entity among the plurality of lower tier entities, queues the data traffic to the virtual port among the plurality of virtual ports that corresponds to the RPI on the particular lower tier entity that was the source of the data traffic. The master switch further includes a switch controller that switches data traffic from the virtual port to an egress port among the plurality of ports from which the data traffic is forwarded.

Abstract: Ein Switching-Netzwerk enthält eine obere Ebene mit einem Master-Switch und eine untere Ebene mit mehreren Entitäten der unteren Ebene. Der Master-Switch enthält eine Mehrzahl von Anschlüssen, die jeweils mit einer entsprechenden aus der Mehrzahl von Entitäten der unteren Ebene verbunden sind. Jeder aus der Mehrzahl von Anschlüssen enthält eine Mehrzahl von virtuellen Anschlüssen, die jeweils einer entsprechenden aus einer Mehrzahl von fernen physischen Schnittstellen (RPIs) an der Entität der unteren Ebene entsprechen, die mit diesem Anschluss verbunden ist. Jeder aus der Mehrzahl von Anschlüssen enthält außerdem eine Empfangsschnittstelle, die in Reaktion auf den Empfang von Datenverkehr von einer bestimmten Entität der unteren Ebene aus der Mehrzahl von Entitäten der unteren Ebene den Datenverkehr in Warteschlangen zu dem virtuellen Anschluss aus der Mehrzahl von virtuellen Anschlüssen einreiht, der der RPI in der bestimmten Entität der unteren Ebene entspricht, bei der es sich um die Quelle des Datenverkehrs handelt. Der Master-Switch enthält ferner eine Switch-Steuereinheit, die Datenverkehr von dem virtuellen Anschluss zu einem Ausgangsanschluss aus der Mehrzahl von Anschlüssen schaltet, von dem der Datenverkehr weitergeleitet wird.
