  • Patent number: 12231558
    Abstract: A network interface card, such as a SmartNIC, is used to provide encryption, such as network encryption virtual function (NEVF), for a virtual machine, so that a customer can control network keys in a virtual cloud network. The NEVF includes a memory device (e.g., SRAM) and a crypto processor (e.g., a crypto core). The memory device stores a crypto key. The crypto processor uses the crypto key to encrypt data to and from a virtual machine in the virtual cloud network. A key management system can be used to securely transfer crypto keys to the NEVF. Having one NEVF per virtual machine can enable a customer to manage the crypto key for a virtual cloud network.

  • Patent number: 12182599
    Abstract: Aspects of the present application relate to systems, methods and non-transitory computer readable media for network virtualization in a rack-based switch. The method can include sending a communication from a first virtual machine (“VM”) instantiated on a first host machine to a first network virtualization Top of Rack (“ToR”) switch. The first network virtualization ToR can include a peripheral component interconnect express (“PCIe”) switch coupled to a plurality of host-side Ethernet ports, a virtualization device communicatingly coupled to the PCIe switch, which virtualization device can include a plurality of virtualization functions, and a switching ASIC coupled to the virtualization device and to a network-side Ethernet port. The method can include forming the communication into an Internet Protocol (“IP”) packet with a first virtualization function of the virtualization device, and sending the IP packet to a second VM with the switching ASIC.

  • Patent number: 12177120
    Abstract: Techniques for loop prevention while allowing multipath in a virtual L2 network are described. In an example, a network virtualization device can generate a first L2 bridge protocol data unit by applying a first loop detection protocol specific to only the first port and the first host machine. The network virtualization device can transmit, to the first compute instance via the first port, a first frame that includes the first L2 BPDU. The network virtualization device can receive, from the first compute instance via the first port, a second frame. The network virtualization device can determine that the second frame comprises the first L2 BPDU. The network virtualization device can determine that a loop exists between the network virtualization device and the first compute instance based on the first loop detection protocol and the first L2 BPDU of the second frame.

  • Publication number: 20240411584
    Abstract: A method for providing a dedicated region cloud at customer is provided. A first physical port of a network virtualization device (NVD) included in a datacenter is communicatively coupled to a first top-of-rack (TOR) switch and a second TOR switch. A second physical port of the NVD is communicatively coupled with a network interface card (NIC) associated with a host machine. The second physical port provided a first logical port and a second logical port for communications between the NVD and the NIC. The NVD receives a packet from the host machine via the first logical port or the second logical port. Upon receiving the packet, the NVD determines a particular TOR, from a group including the first TOR and the second TOR, for communicating the packet. The NVD transmits the packet to the particular TOR to facilitate communication of the packet to a destination host machine.

  • Publication number: 20240396794
    Abstract: Generally described, systems and methods are provided for monitoring and detecting causes of failures of network paths. The system collects performance information from a plurality of nodes and links in a network, aggregates the collected performance information across paths in the network, processes the aggregated performance information for detecting failures on the paths, analyzes each of the detected failures to determine at least one root cause, and initiates a remedial workflow for the at least one root cause determined. In some aspects, processing the aggregated information may include performing a statistical regression analysis or otherwise solving a set of equations for the performance indications on each of a plurality of paths. In another aspect, the system may also include an interface which makes available for display one or more of the network topology, the collected and aggregated performance information, and indications of the detected failures in the topology.

  • Patent number: 12074791
    Abstract: Techniques for controlling packet flows through the generation of packet flow rules are described. In an example, a network virtualization device receives network data. The network virtualization device determines a set of networks of a virtual network based on the network data. The network virtualization device receives flow data of the customer. The network virtualization device generates a packet flow rule based on the flow data and the set of networks. The packet flow rule defines a network boundary of one or more networks such that a first packet having a destination within the network boundary can flow and such that a second packet having a destination outside of the network boundary is to be dropped. The network virtualization device stores the packet flow rule in association with the compute instance.

  • Patent number: 12074846
    Abstract: Techniques are disclosed for scaling an IP address in overlay networks without using load balancers. In certain implementations, an overlay IP address can be attached to multiple compute instances via virtual network interface cards (VNICs) associated with the multiple compute instances. Traffic directed to the multi-attached IP address is distributed across the multiple compute instances. In some other implementations, ECMP techniques in overlay networks are used to scale an overlay IP address. In forwarding tables used for routing packets, the IP address being scaled is associated with multiple next hop paths to multiple network virtualization devices (NVDs) associated with the multiple compute instances. When a particular packet directed to the overlay IP address is to be routed, one of the multiple next hop paths is selected for routing the packet. This enables packets directed to the IP address to be distributed across the multiple compute instances.

  • Publication number: 20240283852
    Abstract: When a cloud services provider infrastructure (CSPI) receives a request from an administrator to perform an operation on an appliance, a load balancer may select a first server within the CSPI to process the request. If the first server does not have a connection with the appliance, the first server may generate a redirect response that includes server identification information identifying a particular server having a pre-established connection with the appliance. The first server may send the redirect response to the application that the administrator used to send the request. The application may then generate a second request that includes the server identification information, and send the second request to the CSPI. A load balancer in the CSPI may then forward the second request to the particular server, and the particular server may use the pre-established connection to send a request to the appliance requesting performance of the operation.
