    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： 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 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.
