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 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: Examples described herein relate to a Transport Layer Security (TLS) offload engine to: based on detection of encrypted data unassociated with a previously detected data header: search for one or more data headers; identify at least two candidate data headers for validation; and based on receipt of an indication that the at least two candidate data headers are valid, perform decryption of received data in one or more packets. In some examples, the TLS offload engine is to: based on receipt of an indication that one or more of the at least two candidate data headers is not a valid header, search for two or more other candidate data headers.
