Abstract: In some examples, for process-to-process communication, such as in function linking, a virtual channel can be provisioned to provide virtual machine to virtual machine communications. In response to a transmit request from a source virtual machine, the virtual channel can cause a data copy from a source buffer associated with the source virtual machine without decryption or encryption. The virtual channel provisions a key identifier for the copied data. The destination virtual machine can receive an indication data is available and can cause the data to be decrypted using a key accessed using the key identifier and source address of the copied data. In addition, the data can be encrypted using a second, different key for storage in a destination buffer associated with the destination virtual machine. In some examples, the key identifier and source address is managed by the virtual channel and is not visible to virtual machine or hypervisor.

Abstract: An apparatus includes an interface to memory, and a processor to execute one or more instructions. The instructions cause the processor to receive, via an application programming interface (API), a plurality of packets, respective packets of the plurality of packets comprising a respective header and a respective payload. Further, the instructions cause the processor to determine, by a QUIC protocol stack, to encrypt the plurality of packets in parallel. Further, the instructions cause the processor to encrypt the payloads of the plurality of packets in parallel. Further, the instructions cause the processor to encrypt the headers of the plurality of packets in parallel.

Abstract: Various systems and methods for implementing protocol state aware power management are described herein. A network interface device for implementing protocol state aware power management includes circuitry to provide a direct memory access interface; medium access control (MAC) circuitry to interface with a network; and control circuitry to: classify packets received at the MAC circuitry as packets used to open network connections or packets used to close network connections; maintain statistics of packets used to open network connections and packets used to close network connections; calculate a power hint based on the statistics of packets used to open connections and packets used to close network connections; and write a receive descriptor to a host memory using the direct memory access interface, the receive descriptor including a power hint field with the power hint, the power hint used by a host processor to scale processor power based on the power hint.

Abstract: Methods and apparatus for secure networking protocol optimization via NIC hardware offloading. Under a method, security offload entries are cached in a flow table or a security database offload table on a network interface coupled to a host that implements a host security database mapping flows to Security Association (SA) contexts. Each security offload entry includes information identify a flow and information, such as an offset value, to locate a corresponding entry for the flow in the host security database. Hardware descriptors for received packets that belong to flows with matching security offload entries are generated and marked with the information used to locate the corresponding entries in the host security database. The hardware descriptors are processed by software on the host and the location information is used to de-reference the location of applicable entries in the host security database.

Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.
