Abstract: A method includes receiving in a network element a packet, which includes a delay field that indicates an overall time delay accumulated by the packet until arriving at the network element. Upon receiving the packet, an interim value is substituted in the delay field. The interim value is indicative of a difference between the overall time delay and an arrival time of the packet at the network element. Before sending the packet from the network element, the overall time delay is updated in the delay field based on the interim value and on a departure time at which the packet is to exit the network element. The packet, including the updated overall time delay, is transmitted from the network element.

Abstract: A network device includes a hardware pipeline to process a network packet to be encrypted. A portion of the hardware pipeline retrieves information from the network packet and generates a command based on the information. A block cipher circuit is coupled inline within the hardware pipeline. The hardware pipeline includes hardware engines coupled between the portion of the hardware pipeline and the block cipher circuit. The hardware engines parse and execute the command to determine a set of inputs and input the set of inputs and portions of the network packet to the block cipher circuit. The block cipher circuit encrypts a payload data of the network packet based on the set of inputs.

Abstract: A method includes detecting, by an accelerator of a networking device, a serial number of a first data packet is out of order with respect to a previous data packet within a first flow of data packets associated with a packet communication network, wherein the serial number is assigned to the first data packet according to a transport protocol. The method includes reconstructing context data associated with the first flow of data packets, wherein the context data comprises encoding information for encoding of data records containing data conveyed in payloads of data packets in the first flow of data packets according to a storage protocol. The method includes using, by the accelerator, the reconstructed context data in processing a data record associated with a second data packet within the first flow, wherein the second data packet is subsequent to the first data packet in the first flow of data packets.

Abstract: A confidential computing (CC) apparatus includes a CPU and a peripheral device. The CPU is to run a hypervisor that hosts one or more Trusted Virtual Machines (TVMs). The peripheral device is coupled to the CPU and to an external memory. The CPU includes a TVM-Monitor (TVMM), to perform management operations on the one or more TVMs, to track memory space that is allocated by the hypervisor to the peripheral device in the external memory, to monitor memory-access requests issued by the hypervisor to the memory space allocated to the peripheral device in the external memory, and to permit or deny the memory-access requests, according to a criterion.

Abstract: A system includes a host processor, which has a host memory and is coupled to store data in a non-volatile memory in accordance with a storage protocol. A network interface controller (NIC) receives data packets conveyed over a packet communication network from peer computers containing, in payloads of the data packets, data records that encode data in accordance with the storage protocol for storage in the non-volatile memory. The NIC processes the data records in the data packets that are received in order in each flow from a peer computer and extracts and writes the data to the host memory, and when a data packet arrives out of order, writes the data packet to the host memory without extracting the data and processes the data packets in the flow so as to recover context information for use in processing the data records in subsequent data packets in the flow.
