    摘要： A network virtualization layer for an information handling system in which a physical machine coupled to a network is divided into a plurality of logical partitions, each of which has a host system residing thereon. In response to receiving a set command from one of the host systems specifying a data link layer (layer 2) address, the virtualization layer associates the data link layer address with the host system and forwards to the host system data packets specifying the data link layer address as a destination address. Unicast packets are forwarded to the single host system specifying the destination address as an individual MAC address, while multicast packets are forwarded to each host system specifying the destination address as a group MAC address. A host system may also specify a virtual LAN (VLAN) ID, which is used to scope the forwarding of packets to host systems sharing that VLAN ID.

    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 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： A facility is provided to allow retrieval of specific parameters by a communications stack (e.g., TCP/IP) of a multi-partitioned processing system from a shared network adapter coupling the processing system to a network. The processing system includes multiple communications stacks, each of which registers internet protocol (IP) addresses with the network adapter in an address resolution table shared by the multiple communications stacks. The facility includes query request and reply commands for selectively retrieving specific data from the shared address resolution table, wherein the specific data can include: local registered IP addresses for a communications stack issuing a query request, network address resolution entries associated with a particular HOME IP address, HOME IP addresses of one or more other communications stacks sharing the network adapter, IP addresses owned by other entities on the network, IP addresses which are in the address cache, as well as other types of data.

    摘要： A method and apparatus for exchanging data in a network computing system having a main storage capable of connecting to at least one application server and an interface element with at least one adapter capable of establishing processing communication with at least one application user(s). A state change signalling protocol is used for transfer of data between the main storage and said adapter. In addition a queuing mechanism is established in the main storage having a plurality of queues each with a plurality of buffers. Some of these queues are dedicated to be input and others as output queues. By applying the protocol each input and output data buffer is associated with each of the active input and output queues. In this manner the input and output buffers are managed by placing the buffers into various states which are maintained in a special location that is set aside and is associated with each buffer. After complete transmission of data, the state of each such buffer is changed in order to make it buffer available for reuse.
