Abstract: A system comprises a first processing block configured to receive, from a first local resource, a formatted transaction in a format that is not recognizable by a remote endpoint; determine a first transaction category, from among a plurality of transaction categories, of the formatted transaction based on content of the formatted transaction; perform one or operations on the formatted transaction based on the first transaction category to form a reformatted transaction in a format that is recognizable by the remote endpoint; and place the reformatted transaction in a queue for transmission to the remote endpoint.

Abstract: A network node includes a bus switching element, and a network adapter, an accelerator and a host, all coupled to communicate via the bus switching element. The network adapter is configured to communicate with remote nodes over a communication network. The host is configured to establish a RDMA link between the accelerator and the RDMA endpoint by creating a Queue Pair (QP) to be used by the accelerator for communication with the RDMA endpoint via the RDMA link. The accelerator is configured to exchange data, via the network adapter, between a memory of the accelerator and a memory of the RDMA endpoint.

Abstract: Apparatus including a first interface to a host processor, a second interface to transmit and receive data packets having headers and payloads, to and from a packet communication network, a memory holding context information regarding a flow of the data and assigning serial numbers to the data packets in the flow, according to a session-layer protocol, and processing circuitry between the first and second interfaces and having acceleration logic, to decode the data records according to the session-layer protocol, using and updating the context information based on the serial numbers and the data records of the received packets, and processing circuitry writing the decoded data records through the first interface to a host memory. The acceleration logic, upon receiving in a given flow a data packet containing a serial number that is out of order, reconstructs the context information and applies that context information in decoding data records in subsequent data packets in the flow.

Abstract: A method for data transfer includes receiving in an operating system of a host computer an instruction initiated by a user application running on the host processor identifying a page of virtual memory of the host computer that is to be used in receiving data in a message that is to be transmitted over a network to the host computer but has not yet been received by the host computer. In response to the instruction, the page is loaded into the memory, and upon receiving the message, the data are written to the loaded page.

Abstract: A method for data transfer includes receiving in an input/output (I/O) operation a first segment of data to be written to a specified virtual address in a host memory. Upon receiving the first segment of the data, it is detected that a first page that contains the specified virtual address is swapped out of the host memory. At least one second page of the host memory is identified, to which a second segment of the data is expected to be written. Responsively to detecting that the first page is swapped out and to identifying the at least one second page, at least the first and second pages are swapped into the host memory. After swapping at least the first and second pages into the host memory, the data are written to the first and second pages.

Abstract: A computerized system for efficient interaction between a host, the host having a first operating system, and a second operating system, the system comprising a subsystem on the second operating system which extracts data, directly from a buffer which is local to the host, wherein the system is operative for mapping memory from one bus associated with the first operating system to a different bus, associated with the second operating system and from which different bus the memory is accessed, thereby to emulate a connection between the first and second operating systems by cross-bus memory mapping.

Abstract: A method in a network node that includes a host and an accelerator, includes holding a work queue that stores work elements, a notifications queue that stores notifications of the work elements, and control indices for adding and removing the work elements and the notifications to and from the work queue and the notifications queue, respectively. The notifications queue resides on the accelerator, and at least some of the control indices reside on the host. Messages are exchanged between a network and the network node using the work queue, the notifications queue and the control indices.
