摘要： A solution for reducing latency in a host computing device communicating with network-attached devices over a network. The host includes two network adapters that each support bidirectional communications with the host. The solution includes a dual module that represents the two network adapters as a single logical interface to both the host and the network-attached devices. An inbound module directs inbound data sent to the interface by the devices through one of the network adapters, while an outbound module directs outbound data sent to the interface by the host through the other. In one embodiment, the outbound module is responsible for intercepting data sent to the interface and sending it through the network adapter dedicated to outbound communications. The solution also includes a mode module to enable the latency reduction apparatus, and a collapse module that enables bidirectional communications through the remaining network adapter if a network adapter fails.

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： A method, system and computer program product for managing at least two physical links. A TCP/IP stack configures a first interface with attributes. The TCP/IP stack activates the first interface. The TCP/IP stack detects a channel path identifier (CHPID). The TCP/IP stack creates a second interface. The TCP/IP stack associates the second interface with the first interface. The first interface and the second interface are logically linked to exchange traffic corresponding to a single internet protocol address. The TCP/IP stack configures the second interface with at least one attribute. The TCP/IP stack activates the second interface. The two physical links may rely on two different physical link types.

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： The invention ensures that a single and consistent reply is made to an ARP request in a system of connected IP networks. When an adapter becomes active, the relative network on which it resides is determined by transmitting control packets over it and all other adapters known to the host and observing if and where responses are returned to the adapters. One adapter on a network is designated as active. If the same network contains other adapters, they are marked as standby adapters for the purpose of responding to ARP messages. Special processing is provided for offload adapters that perform there own ARP processing.

摘要： Methods, systems (apparatus) and computer program products that control the data rate through a communications adapter having at least one guaranteed bandwidth connection through the communications adapter are provided. The data rate is controlled by assigning to the guaranteed bandwidth connection, a maximum threshold value proportional to the amount of data to be transmitted through the communications adapter in a time interval to satisfy the guaranteed bandwidth of the connection. The amount of data transmitted through the communications adapter for the guaranteed bandwidth connection is then counted so as to provide a connection data count associated with the guaranteed bandwidth. Data transmitted for the communications adapter associated with the guaranteed bandwidth connection is not transmitted to the communications adapter if transmission of the data would cause the connection data count to exceed the maximum threshold value assigned to the guaranteed bandwidth connection. The connection data count is then reset after expiration of the time interval.
