摘要： A method of communication includes receiving, in a network interface device, first and second requests from an initiator process running on an initiator host to transmit, respectively, first and second data to first and second target processes running on one or more target nodes, via a packet network. A single dynamically-connected initiator context is allocated for serving both the first and second requests. A first connect packet referencing the dynamically-connected (DC) initiator context is directed to the first target process so as to open a first dynamic connection with the first target process, followed by transmission of the first data over the first dynamic connection. The first dynamic connection is closed after the transmission of the first data, and a second connect packet is transmitted so as to open a second dynamic connection with the second target process, followed by transmission of the second data.

摘要： An input/output (I/O) device includes a host interface for connection to a host device having a memory, and a network interface, which is configured to transmit and receive, over a network, data packets associated with I/O operations directed to specified virtual addresses in the memory. Processing circuitry is configured to translate the virtual addresses into physical addresses using memory keys provided in conjunction with the I/O operations and to perform the I/O operations by accessing the physical addresses in the memory. At least one of the memory keys is an indirect memory key, which points to multiple direct memory keys, corresponding to multiple respective ranges of the virtual addresses, such that an I/O operation referencing the indirect memory key can cause the processing circuitry to access the memory in at least two of the multiple respective ranges.

摘要： A method for communication, includes allocating, in a network interface controller (NIC) a single dynamically-connected (DC) initiator context for serving requests from an initiator process running on the initiator host to transmit data to multiple target processes running on one or more target nodes. The NIC transmits a first connect packet directed to a first target process and referencing the DC initiator context so as to open a first dynamic connection with the first target process. The NIC receives over the packet network, in response to the first connect packet, a first acknowledgment packet containing a first session identifier (ID). Following receipt of the first acknowledgment packet, the NIC transmits one or more first data packets containing the first session ID over the first dynamic connection from the NIC to the first target process. Dynamic connections with other target processes may subsequently be handled in similar fashion.

摘要： A network communication device includes a host interface, which is coupled to communicate with a host processor, having a host memory, so as to receive a work request to execute a transaction in which a plurality of data blocks are to be transferred over a packet network. Processing circuitry is configured to process multiple data packets so as to execute the transaction, each data packet in the transaction containing a portion of the data blocks, and the multiple data packets including at least first and last packets, which respectively contain the first and last data blocks of the transaction. The processing circuitry is configured to compute a transaction signature over the data blocks while processing the data packets so that at least the first data block passes out of the network communication device through one of the interfaces before computation of the transaction signature is completed.

摘要： A network interface controller includes a host interface, which is configured to be coupled to a host processor having a host memory. A network interface is configured to receive data packets from a network, each data packet including a header, which includes header fields, and a payload including data. Packet processing circuitry is configured to process one or more of the header fields and at least a part of the data and to select, responsively at least to the one or more of the header fields, a location in the host memory. The circuitry writes the data to the selected location and upon determining that the processed data satisfies a predefined criterion, asserts an interrupt on the host processor so as to cause the host processor to read the data from the selected location in the host memory.
