Abstract: Examples described herein relate to an interface and circuitry. The circuitry can perform offloaded performance of a cryptographic handshake with a client in connection with initiation of a quick User Datagram Protocol Internet Connections (QUIC) connection with the client. In some examples, the cryptographic handshake comprises process a first client hello datagram from the client, the first client hello datagram is consistent with QUIC, and the offloaded performance of the cryptographic handshake with the client is offloaded from a processor to the circuitry.

Abstract: Examples described herein relate to a network device apparatus that includes a network interface card to process a received packet. In some examples, based on the received packet only including one or more frames for which acknowledgement of receipt is offloaded to the network interface card, generate an acknowledgement (ACK) message to acknowledge receipt of the received packet. In some examples, a frame for which acknowledgement of receipt is offloaded to the network interface card comprises a STREAM frame compatible with quick User Datagram Protocol (UDP) Internet Connections (QUIC). In some examples, a computing platform is coupled to the network interface card. In some examples, based on the received packet only including any frame for which acknowledgement of receipt is not offloaded to the network interface, the computing platform is to generate an ACK message for the received packet.

Abstract: Apparatus and method for performing address pre-translation to enhance direct memory access by hardware subsystems is described herein. An apparatus embodiment includes a processor to execute an enqueue instruction to submit, to a hardware subsystem, a job descriptor describing a job to be performed. The job descriptor includes virtual addresses of memory locations in which data required to perform the job are stored. An input-output memory management unit (IOMMU) is to obtain the address translations for the virtual addresses responsive to a pre-translation request from the processor. The address translations is obtained by the IOMMU prior to receiving a memory access request from the hardware subsystem. The IOMMU is to retrieve the data from the memory location using the address translations and to provide the retrieved data to the hardware subsystem to fulfill the request.

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: 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.

Abstract: Examples described herein relate to an apparatus comprising: at least one processor, when operational, to: perform a command to submit a work descriptor to a device, wherein: submission of the work descriptor causes an attempt to perform a substitution of an address in the work descriptor before submitting the work descriptor to the device. In some examples, the address comprises a guest virtual address (GVA) and the substitution of an address comprises replacement of the GVA with a host physical address (HPA) corresponding to the GVA. In some examples, the at least one processor is to: substitute the address in the work descriptor with an address translation of the address in the work descriptor if the address translation is available for access by a processor that performs the command.

Abstract: Examples described herein relate to a switch comprising a programmable data plane pipeline, wherein the programmable data plane pipeline is configured to provide microservice-to-microservice communications within a service mesh. In some examples, to provide microservice-to-microservice communications within a service mesh, the programmable data plane pipeline is to perform a forwarding operation for a communication from a first microservice to a second microservice. In some examples, to perform a forwarding operation for a communication from a first microservice to a second microservice, the programmable data plane pipeline is to utilize a reliable transport protocol.
