摘要： A method, computer program product, and device are provided for transparent separation of traffic. A communication interface is configured to transmit and receive traffic over a network. A stack is configured to dynamically identify the traffic as interactive traffic and non-interactive traffic. When the stack identifies the non-interactive traffic, the stack is configured to move the non-interactive traffic to a non-interactive queue.

摘要： A method, system, and program product for a data processing system having multiple hosts which dynamically determines blocking of packets in the data processing system. A connection is established between a host and an adapter for communication with a Local Area Network. A set of parameters is established for blocking packets transmitted from the adapter to the host. The set of parameters is stored in the adapter to be used by that connection. The packets transmitted from the adapter to the host are grouped or blocked in accordance with the set of parameters for that connection. Periodically, the packets being transmitted from the adapter to the host are evaluated for determining changes in the parameters. Changes to the set of parameters are recorded in the adapter for that connection to the host. Where there are multiple connections established between the adapter and multiple hosts, a set of parameters to be used for each connection is established such that packets are blocked in accordance with a respective set of parameters for a respective one of the hosts.

摘要： A current value of a changing operating-system-level condition can be determined, wherein the operating-system level condition is a condition of a host related to an operating system resource utilization or an operating system experienced latency. The operating-system level condition can be a condition of a layer of the OSI model above the Data Link Layer. An inbound blocking factor algorithm can execute that uses the determined current value as a variable. A value for an inbound blocking factor can be generated as a result of executing the inbound blocking factor algorithm. The generated value can be utilized as the inbound blocking factor to determine a manner in which incoming messages are to be conveyed from a network adaptor, through an adaptor interface boundary, to an operating system of the host.

摘要： Data received over a shared network interface is directly placed by the shared network interface in a designated memory area of a host. In providing this direct memory access, the incoming data packets are split, such that the headers are separated from the data. The headers are placed in a designated area of a memory buffer of the host. Additionally, the data is stored in contiguous locations within the buffer. This receive and store is performed without interruption to the host. Then, at a defined time, the host is interrupted to indicate the receipt and direct storage of the data.

摘要： A data connection of a shared resource is placed in isolation mode to remove its ability to communicate with other data connections of the shared resource. This ability to isolate the data connection is dynamic in that it can be turned on/off at any time. This provides increased data security for the entities using the data connection.

摘要： A method and system are disclosed for network adaptor optimization and interrupt reduction. The method may generate an immediate I/O interrupt notification to a host device driver in response to receiving data from a network. The method may also update an inbound buffer list based on the received data in the inbound buffer queue. Furthermore, the method may set the buffer state from an empty state to a primed state to indicate that the received data is available for processing. The method may also build an outbound buffer list based on outgoing data and add the outgoing data to an outbound buffer queue. Furthermore, the method may set a buffer state from an empty state to a primed state to indicate that the outgoing data is prepared for transmitting and signal a network adaptor with a notification signal.

摘要： Computer program products and methods for efficient handling of queued-direct input/output (QDIO) requests and completions at an adapter in communication with an I/O device are provided. A method includes accessing a queue with one or more storage block address lists (SBALs), where each SBAL includes a plurality of storage block address list entries (SBALEs) and is associated with an SLSB. The method further includes reading an SBAL count in one of the SBALEs, where the SBAL count indicates a number of the SBALs forming an I/O request to the I/O device. In response to determining that the SBAL count is greater than one, a number of the SBALs from the queue and associated SLSBs equivalent to the SBAL count are prefetched without waiting for a notification of completion of each of the SBALs forming the I/O request, and states of the associated SLSBs transition from adapter-owned to program-owned.
