Abstract: Aspects of the present disclosure are directed to systems, methods, and computer readable media for dynamic data transfer rate control. One method includes alternating a network device between a plurality of supported data transfer rates that are supported by the network device to achieve an unsupported data transfer rate that is not supported by the network device. Another method includes adding one or more dummy work descriptors to a data stream, and transmitting the data stream including the one or more dummy work descriptors at a supported data transfer rate that is supported by a network device to achieve an effective unsupported data transfer rate that is not supported by the network device.

Abstract: A communication apparatus includes input circuitry, an encapsulator, transmission circuitry and flow control circuitry. The input circuitry is to receive packets from a data source in accordance with a first communication protocol that employs credit-based flow control. The encapsulator is to buffer the packets in a memory buffer and to encapsulate the buffered packets in accordance with a second communication protocol. The transmission circuitry is to transmit the encapsulated packets over a communication link in accordance with the second communication protocol. The flow control circuitry is to receive from the encapsulator buffer status indications that are indicative of a fill level of the memory buffer, and to exchange credit messages with the data source, in accordance with the credit-based flow control of the first communication protocol, responsively to the buffer status indications.

Abstract: A peripheral device coupled to a host includes a network interface, a packet processor, and a Data Processing Unit (DPU). The packet processor receives from a communication network, via the network interface, packets that originated from a source in an original order and received at the peripheral device in as order different from the original order. The packet processor splits the received packets into headers and payloads, sends the payloads for storage in a host memory and sends the headers without the payloads for storage in a DPU memory, and based on the headers produces a hint indicative of processing to be applied to the headers, by the DPU, for identifying the original order. Based on the hint, the DPU identifies the original order of the packets by applying the processing indicated by the hint to respective headers in the DPU memory, and notifies the host of the original order.

Abstract: In one embodiment, a data communication device includes a network interface controller to process packets received from at least one of a host device for sending over a network, and at least one remote device over the network, at least one processor to execute computer instructions to receive a configuration, and extract filtering rules from the configuration, and at least one hardware accelerator to receive the filtering rules from the at least one processor, and filter the packets based on the rules so that some of the packets are dropped and some of the packets are forwarded to the at least one processor to send data based on the forwarded packets to another device.

Abstract: The technology disclosed herein enables an auxiliary device to run a service that can access and analyze data of a Trusted Execution Environment (TEE). The auxiliary device may establish an auxiliary TEE in the auxiliary device and establish a trusted communication link between the auxiliary TEE and the TEE (i.e., primary TEE). The primary TEE may execute a target program using the primary devices of a host device (e.g., CPU) and the auxiliary TEE may execute a security program using the auxiliary device (e.g., DPU). In one example, the primary and auxiliary TEEs may be established for a cloud consumer and the auxiliary TEE may execute a security service that can monitor data of the primary TEE even though the data is inaccessible to all other software executing external to the primary TEE (e.g., inaccessible to host operating system and hypervisor).

Abstract: A system and method are provided. In one example, a system is disclosed that includes a memory device and a first interface configured to connect with a first external device. The interface may include a device side that enables a first data exchange with the first external device and a system side that enables a second data exchange with the memory device, where the system side further enables an exchange of platform hints between the first interface and the memory device. The system may also include a hinting unit that populates the platform hints in an address bit.

Abstract: A network device in a communication network includes a controller and processing circuitry. The controller is configured to manage execution of an operation whose execution depends on inputs from a group of one or more work-request initiators. The processing circuitry is configured to read one or more values, which are set by the work-request initiators in one or more memory locations that are accessible to the work-request initiators and to the network device, and to trigger execution of the operation in response to verifying that the one or more values read from the one or more memory locations indicate that the work-request initiators in the group have provided the respective inputs.
