摘要： An approach is provided which a system selects a first virtual function from a plurality of virtual functions executing on a network adapter that includes a memory area. Next, the system allocates, in the memory area, a memory corresponding to the first virtual function. The system then stores one or more translation entries in the allocated memory partition, which are utilized to send data traversing through the first virtual function. As such, the system sends, utilizing one or more of the translation entries, the data packets from the network adapter to one or more destinations. In turn, the system dynamically resizes the memory partition based upon an amount of the memory partition that is utilized to store the one or more translation entries.

The master switch includes a plurality of ports each coupled to a respective one of the plurality of lower tier entities. Each port 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 port also includes a receive interface that, responsive to data traffic from a particular lower tier entity, queues the data traffic to the virtual port 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 from which the data traffic is forwarded.

摘要： Techniques 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.

摘要： Systems and methods for switching traffic include a physical machine running source and destination virtual machines (VMs). The source VM issues a data unit addressed to the destination VM. The physical machine has a physical network interface in communication with the VMs. The physical network interface transmits a sub-packet, which includes a partial portion of the data unit, over a network while a majority portion of the data unit remains at the physical machine. A network switch on the network receives the sub-packet transmitted by the physical network interface. The network switch performs one or more OSI Layer 2 through Layer 7 switching functions on the sub-packet and returns that sub-packet to the physical network interface. The physical network interface identifies the data unit stored in the memory in response to the sub-packet returned from the network switch and forwards the identified data unit to the destination VM.

摘要： 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.
