摘要:
A system includes a server including: logic adapted for receiving traffic from a virtual machine (VM), the traffic including at least one packet, logic adapted for hashing at least a portion of the at least one packet according to a hashing algorithm to obtain a hash value, and logic adapted for selecting an uplink based on the hash value; at least one accelerated network interface card (NIC), each accelerated NIC including: network ports including multiple Peripheral Component Interconnect express (PCIe) ports adapted for communicating with the server and a network, each network port including an uplink, logic adapted for encapsulating the at least one packet into an overlay-encapsulated packet, logic adapted for storing a media access control (MAC) address corresponding to the selected uplink as a source MAC (SMAC) address in an outer header of the overlay-encapsulated packet, and logic adapted for sending the overlay-encapsulated packet via the selected uplink.

摘要:
Systems are provided for overlaying a virtual network on a physical network in a data center environment. An overlay system is arranged in an overlay virtual network to include an overlay agent and an overlay helper. The overlay agent is implemented in an access switch. The overlay helper is implemented in an end station that is in communication with the access switch. Overlay parameters in compliance with an in-band protocol are transmitted between the overlay agent and the overlay helper.
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:
A technique for operating a virtual switch includes determining network connection requirements for virtual machines controlled by a virtual machine monitor. Resources available, for processing data traffic of the virtual machines, are also determined. Finally, based on the network connection requirements and the resources available, a port of a virtual switch is selected to operate as a virtual Ethernet bridge or a virtual Ethernet port aggregator.

摘要:
Packet processing logic of a host system's virtualization manager detects packets on the ingress or the egress path to/from a virtual port having three bitmap arrays for processing packets within a virtual local area network (VLAN). The logic checks the VLAN identifier (VID) of the packet to determine, based on an offset position within the corresponding bitmap array, whether the port supports the VLAN. Both the ingress array offset position and egress array offset positions correspond to the value of the VID, and are set within the specific bitmap array during configuration of the VLAN on the port. When the VLAN is supported by the port, the logic enables the packet to be processed by the port. Otherwise, the logic discards the packet. A strip bitmap array indicates when a packet's VID should be removed prior to forwarding the packet on the egress of a port (or destination port).
