    摘要： A link extender is used for extending links between end nodes or router nodes in a system area network. Nodes in the network transmit link alive symbols to indicate that a link is alive. The link extender includes a link alive propagation feature for propagating the loss of link alive between ports of the link extender.

    摘要： A data communicating device, having a number of inputs whereat data is received for communication from one of a number of outputs of the device, includes apparatus for selecting one of the inputs based upon a comparison of accumulated bias values that can change over time when an input is kept waiting. Each input is provided an assigned bias value from which is developed the accumulated bias value that is compared with that of other inputs arbitrating for access to an output. The output selects one of the inputs, based upon the comparison, and the accumulated bias value of the selected input is diminished by the sum of the assigned bias values of the inputs participating in the arbitration, but not selected, while the accumulated bias values of the other participants are each increased by their corresponding assigned bias values. Thereby, numbers of inputs having data destined for the same output will have their chance of gaining access to the output increased the longer they wait; conversely, inputs which do gain access have their chances for immediate subsequent access decreased in favor of allowing other inputs access.

    摘要： A multiple processing system, comprises at least a pair of processor units communicatively connected to a number of peripheral devices through a network that includes routing devices interconnected to route information in the form of message packets sent between the processor units and peripheral devices. Data describing the topographical interconnections of the system elements is maintained with the system. A service processor accesses the data, determines therefrom the topographical interconnections forming the network, assigns addresses/identifications to the system elements, and configures the router devices to establish the most direct routes between system elements for message packets sent on the network.

    摘要： A system and method for facilitating both in-order and out-of-order packet reception in a SAN includes requestor and responder nodes, coupled by a plurality of paths, that maintain the good and bad status of each path and also maintain local copies of a message sequence number. If an error occurs for a transaction over a given path, the requestor informs the responder, over a good path, that the given path has failed and both nodes update their path status to indicate that the given path is bad. A barrier transaction is used by the requestor to determine whether the error is transient or permanent, and, if the error is transient, the requestor retries the transaction.

    摘要： A digital control circuit is constructed to use a single signal line for the dual functions of control and sensing the presence of the controlled device. The control circuit includes a driver element having an output capable of being placed in a high impedance allowing the signal line to be pulled to a first predetermined voltage potential when the controlled device is connected thereto, and a second voltage potential when the controlled device is absent therefrom. A receiver circuit monitors the signal line to sense presence of the one or the other of the voltage potentials.

    摘要： A biased arbitration technique utilizes a transpose table to arbitrate access to a shared resource. Each column of transpose table is a binary bias vector encoding a bias value assigned to one of the requestors. The rows of the table are fetched to assure that requestors having high bias values are granted more frequent access to the shared resource. A look-ahead feature skips rows having all zeros and an unbiased cycle that assures all requesting ports are serviced regardless of their bias values.
