Abstract: A method including providing a hardware-implemented networking system having a sending device, the sending device being configured to communicate with a receiving device via a communications medium, and performing the following at the sending device: providing an initial value for transmission timeout and setting a current value for transmission timeout to the initial value, sending one or more packets associated with a given queue from the sending device to the receiving device via the communications medium, setting a packet transmission timeout timer associated with the given queue to the current value for transmission timeout; and upon expiration of a packet transmission timeout timer associated with the given queue, performing the following: A. determining whether one or more packets have been successfully received by the receiving device, and performing one or both of the following steps B and C: B. if one or more packets have been successfully received by the receiving device, decreasing the current value for transmission timeout, and C. if no packets have been successfully received by the receiving device, increasing the current value for transmission timeout. Related apparatus and methods are also provided.

Abstract: A network device includes a first interface, a second interface, and circuitry. The first interface is configured to communicate at least with a memory. The second interface is configured to communicate over a network with a peer network device. The circuitry is configured to receive a request to transfer data over the network between the memory and the peer network device in accordance with (i) a pattern of offsets to be accessed in the memory and (ii) a memory key representing a memory space to be accessed using the pattern, and to transfer the data in accordance with the request.

Abstract: Network communication is carried out by transmitting messages in accordance with a predefined data exchange protocol among nodes that include a master domain and a plurality of client domains. A list of expected messages has a tail portion in the master domain and respective head portions in the client domains. A search is conducted for a match between the tag of a received message to tags in a list of unexpected messages that is maintained in the master domain. Upon a failure to find the match the receive is added to the list of expected messages. If a match is found then data in the message is written into a data buffer.

Abstract: Systems and methods are described herein for processing data packets. An example network adapter may include a network interface operatively coupled to a communication network and packet processing circuitry operatively coupled to the network interface. The packet processing circuitry is configured to receive, via the network interface, a plurality of data packets associated with a message; determine, for each data packet, at least one corresponding reserved stride in a strided buffer; store each data packet in the at least one corresponding reserved stride; process the strided buffer upon storing the plurality of data packets in a corresponding plurality of reserved strides; and generate a completion notification indicating that the plurality of data packets in the strided buffer has been processed.

Abstract: An apparatus includes a network interface and circuitry. The network interface is configured to connect to a communication network. The circuitry is configured to receive, from a host, first RDMA requests in accordance with a first transport service type, for transferring data between an initiator process running on the host and one or more responder processes running on one or more remote computers, to convert the first RDMA requests into second RDMA requests in accordance with a second transport service type, different from the first transport service type, to communicate messages corresponding to the second transport service type with the remote computers, to convert completions, which are received from the one or more remote computers in accordance with the second transport service type, into corresponding completions to the first RDMA requests in accordance with the first transport service type, and to send the corresponding completions to the initiator process.

Abstract: A system is described which monitors accesses to one or more peers using queue pairs (QPs). Each access is associated with a respective peer of the one or more peers. The system identifies, based on one or more of a rate and a count of the monitored accesses to the one or more QPs, a first peer of the one or more peers. In response to identifying the first peer, a reliable connection QP is established for the first peer of the one or more peers.
