  • Patent number: 12231339
    Abstract: Methods and apparatus for extending OpenvSwitch (OVS) megaflow offloads to hardware to address hardware pipeline limitations. Under a method implemented on a compute platform including a Network Interface Controller (NIC) having one or more ports and running software including OVS software and a Linux operating system having a kernel including a TC-flower module and a NIC driver a new megaflow is created with a mask in the OVS software employing a subset of microflow fields for a packet. The microflow fields and the megaflow mask is sent to the NIC driver. A new megaflow is implemented in the NIC driver employing a subset of the microflow fields and the NIC driver creates a new hardware flow on the NIC employing a packet match scheme using all the microflow fields. The NIC also programs a NIC hardware pipeline with the new hardware flow using a match scheme that may depend on the available hardware resources, such as the size of a TCAM.

  • Patent number: 12170624
    Abstract: Examples described herein relate to one or more processors, when operational, to execute instructions stored in memory device, to cause performance of: execute a driver that is to: negotiate capabilities of hardware with a control plane for a virtualized execution environment and limit capabilities of the hardware available to the virtualized execution environment based on a service level agreement (SLA) associated with the virtualized execution environment. In some examples, the driver is to advertise hardware capabilities requested by the virtualized execution environment. In some examples, the control plane is to set capabilities of a hardware available to the virtualized execution environment based on the SLA.

    Abstract: A set of threads of an application are identified to be executed on a platform, where the platform comprises a multi-node architecture. A set of queues of an I/O device of the platform are reserved and associated with one of a plurality of nodes in the multi-node architecture. Data is received at the I/O device, where the I/O device is included in a particular one of the plurality of nodes. Response data is generated through execution of a thread in the set of threads using a processing core and memory of the particular node, and the response data is caused to be sent on the I/O device based on inclusion of the I/O device in the particular node.

  • Patent number: 10135687
    Abstract: A virtual switch connected to at least one virtual machine of multiple virtual machines communicatively connected through an overlay network, receives a data packet, each of the virtual machines configured within a separate one of multiple virtual groups in the overlay network, the data packet comprising a packet header comprising at least one address. The virtual switch receives a virtual group identifier for the at least one address from at least one address resolution service returning the virtual group identifier and a resolved address for the at least one address, in response to an address resolution request for the at least one address. The virtual switch sends the data packet through the virtual switch to the resolved address only if the virtual group identifier is allowed according to a filtering policy applied by the virtual switch for a particular virtual group identified by the virtual group identifier.
