  • Scalable network function virtualization service
    Patent number: 12047281
    Abstract: A network function virtualization service includes an action implementation layer and an action decisions layer. On a flow of network traffic received at the service, the action implementation layer performs a packet processing action determined at the action decisions layer.
    Type: Grant

  • Enabling bypass flows for network traffic between devices
    Patent number: 10868758
    Abstract: Bypass flow may be enabled for network traffic between devices. A source device may include a flow identifier in an outbound packet that is sent to a destination device. An inbound packed sent from the destination device may include information that describes a network path between the source device and the destination device. Subsequent outbound packets bound for the destination device may be rewritten based on the information describing the network path to bypass one or more network devices in the network path.

  • Guaranteeing bandwidth for dual-homed hosts in fabric extender topologies
    Patent number: 9473357
    Abstract: Techniques are provided for optimizing bandwidth in a network. Information describing a network bandwidth capacity of a port extender device is received at a switch. The port extender device is connected to the switch. The port extender device is configured to provide ports for the switch. The network bandwidth capacity of the port extender device is compared to a minimum network bandwidth guarantee threshold. If the switch determines that the network bandwidth capacity of the port extender device is below the minimum network guarantee threshold, the switch sends to the port extender device a message configured to cause the port extender to deactivate one or more links between the port extender device and one or more servers in communication with the port extender device.

  • Increasing multi-destination scale in a network environment
    Patent number: 8964530
    Abstract: An example method for increasing multi-destination scale in a network environment is provided and includes receiving a packet at a pair of switches comprising a first switch and a second switch in a network environment, where the first switch is configured as an elected forwarder, and the second switch is configured as a standby forwarder. A fabric extender (FEX) is connected to the first switch and the second switch with a virtual PortChannel. The method further includes forwarding the packet to a host connected to the FEX. The elected forwarder is configured with substantially all multi-destination virtual interfaces (VIFs) on the FEX in a forwarding table. The standby forwarder forwards the packet to the elected forwarder. In specific embodiments, the elected forwarder programs the FEX with the VIFs.
