Abstract: A distributed fabric system has distributed line card (DLC) chassis and scaled-out fabric coupler (SFC) chassis. Each DLC chassis includes a network processor and fabric ports. Each network processor of each DLC chassis includes a fabric interface in communication with the DLC fabric ports of that DLC chassis. Each SFC chassis includes a fabric element and fabric ports. A communication link connects each SFC fabric port to one DLC fabric port. Each communication link includes cell-carrying lanes. Each fabric element of each SFC chassis collects per-lane statistics for each SFC fabric port of that SFC chassis. Each SFC chassis includes program code that obtains the per-lane statistics collected by the fabric element chip of that SFC chassis. A network element includes program code that gathers the per-lane statistics collected by each fabric element of each SFC chassis and integrates the statistics into a topology of the entire distributed fabric system.

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: A switching network includes an upper tier and a lower tier including a plurality of lower tier entities. A master switch in the upper tier, which has a plurality of ports each coupled to a respective lower tier entity, implements on each of the ports 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. Data traffic communicated between the master switch and RPIs is queued within virtual ports that correspond to the RPIs on lower tier entities with which the data traffic is communicated. The master switch enforces priority-based flow control (PFC) on data traffic of a given virtual port by transmitting, to a lower tier entity on which a corresponding RPI resides, a PFC data frame specifying priorities for at least two different classes of data traffic communicated by the particular RPI.

Abstract: A method for providing location independent dynamic port mirroring on distributed virtual switches is disclosed. A controller is provided to configure one or more virtual switches within a group of physical machines to appear as a set of distributed virtual switches. In response to the receipt of a data packet at a port of a physical machine, a determination is made whether or not the port has a monitor port located on the physical machine. If the port has a monitor port located on the same physical machine, a copy of the data packet is sent to the monitor port of the physical machine. If the port has a monitor port located on a different physical machine, a copy of the data packet along with an identification (ID) of the port and an ID of the monitor port are encapsulated, and the encapsulated information are sent to a controller.
