Abstract: A network element processes a data flow in accordance with a communications protocol in which respective incremental sequence numbers are assigned to segments of the data flow. The segments are sent from the network element to the other network element in order of the sequence numbers, and respective acknowledgements are received from the other network element. The acknowledgements may include the highest sequence number of the segments of the flow that were received in the other network element. After transmitting the last segment of the data flow an additional segment is sent to the other network element. When it is determined from an acknowledgement of the additional segment that the last segment of the data flow was not received by the other network element, the last segment is retransmitted.

Abstract: A method for communication includes establishing, using an end-to-end reliable transport context, a channel for exchange of data packets over a network between a first network interface controller (NIC) of a first computing node on the network and a second NIC of a second computing node on the network. The first NIC accepts first and second work items for execution on behalf of different, first and second sender processes, respectively, that are running on the first computing node. The first and second work items are executed by transmitting over the network from the first NIC to the second NIC, using the end-to-end reliable transport context, first and second messages directed to different, first and second receiver process running on the second computing node, using the same end-to-end reliable transport context. The second message is sent before receiving from the second NIC any acknowledgment of the first message.

Abstract: Communication apparatus includes a host interface for connection, via a host bus, to a host processor and a host memory, which is mapped to an address space of the host bus, and a network interface, configured to transmit and receive packets over a network. A local memory is configured to hold data in a memory space that is not mapped to the address space of the host bus. Packet processing circuitry, which is connected between the host interface and the network interface and is connected to the local memory, is configured to receive from the network interface a packet carrying a remote direct memory access (RDMA) request that is directed to an address in the local memory, and to service the RDMA request by accessing the data in the local memory.

Abstract: A method for communication includes posting, by a software process, a set of buffers in a memory of a host processor and creating in the memory a list of labels associated respectively with the buffers. The software process pushes a first part of the list to a network interface controller (NIC), while retaining a second part of the list in the memory under control of the software process. Upon receiving a message containing a label, sent over a network, the NIC compares the label to the labels in the first part of the list and, upon finding a match to the label, writes data conveyed by the message to a buffer in the memory. Upon a failure to find the match in the first part of the list, the NIC passes the message from the NIC to the software process for handling using the second part of the list.

Abstract: A method for communication includes receiving multiple work requests from a process running on a computer to transmit respective messages over a network. A single work item corresponding to the multiple work requests is submitted to a network interface controller (NIC) connected to the computer. In response to the single work item, multiple data packets carrying the respective messages are transmitted from the NIC to the network.

Abstract: A method for steering packets includes receiving a packet and determining parameters to be used in steering the packet to a specific destination, in one or more initial steering stages, based on one or more packet specific attributes. The method further includes determining an identity of the specific destination of the packet in one or more subsequent steering stages, governed by the parameters determined in the one or more initial stages and one or more packet specific attributes, and forwarding the packet to the determined specific destination.

Abstract: A network device includes one or more ports, match-action circuitry, and an action processor. The one or more ports are to exchange packets between the network device and a network. The match-action circuitry is to match at least some of the packets to one or more rules so as to set respective actions to be performed, at least one of the actions including a programmable action. The instruction processor is to perform the programmable action by running user-programmable software code. The instruction processor includes architectural registers, one or more of the architectural registers being accessible by the match-action circuitry, and the match-action circuitry is to write into the architectural registers information for performing the programmable action.

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.
