摘要： A method and network switch for switching data units assigns a unique virtual port to each end-node operating on a physical machine connected to a physical port of network switch. A data unit, sent by a given end-node operating on the physical machine, is received at the physical port. The received data unit is switched to the virtual port assigned to the given end-node. Based on the virtual port assigned to the given end-node, the data unit is switched to a second physical port of the network switch for subsequent forwarding of the data unit towards its destination.

摘要： A data center includes a physical host machine operating a virtualized entity and a network switch having a physical port connected to the physical host machine. To configure the network switch, the network switch has a management module that acquires information about the virtualized entity operating on the physical host machine. The network switch associates the acquired information about the virtualized entity with the physical port, assigns the virtualized entity to a group associated with a traffic-handling policy, and processes packet traffic from the virtualized entity in accordance with the traffic-handling policy. The virtualized entity can be, for example, a virtual machine or a multi-queue network input/output adapter operating on the physical host machine.

摘要： A switching network includes an upper tier having a master switch and a lower tier including a plurality of lower tier entities. The master switch, 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 with which the data traffic is communicated. The master switch applies data handling to the data traffic in accordance with a control policy based at least upon the virtual port in which the data traffic is queued, such that the master switch applies different policies to data traffic queued to two virtual ports on the same port of the master switch.

摘要： In a switching network, each of a plurality of lower tier entities is coupled to each of multiple master switches at an upper tier by a respective one of multiple links. At each of the multiple master switches, a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier are implemented on each of a plurality of ports. Each of the plurality of lower tier entities implements a respective egress port mapping indicating which of its plurality of RPIs transmits egress data traffic through each of its multiple links to the multiple master switches. In response to failure of one of the multiple links coupling a particular lower tier entity to a particular master switch, the particular lower tier entity updates its egress port mapping to redirect egress data traffic to another of the multiple master switches without packet dropping.

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.
