摘要： A data processing system comprises a host computer connected for the transfer of data to and from a plurality of data storage devices arranged in a string, the host computer including communication means comprising first and second ports connecting to first and second communication links, the first and second communication links being connected respectively to first and second data storage devices of said string. A bypassing means is provided between the first and second ports of the host system and the first and second data storage devices, the bypassing means being comprised of an independent bypass circuit on each of the first and second communication links between each of the first and second ports and the first and second data storage devices, the bypassing means being operable to bypass the host computer by connecting the first and second devices only when both of said independent bypass circuits detect a lack of data transfer on their respective links.

摘要： A method and apparatus for recovery from faults in a loop network (400) is provided. The loop network (400) has a host means (402), a first loop and a second loop (406, 408), a plurality of ports (410) connected to each of the loops (406, 408) and a control device (414, 440) on or connected to each loop (406, 408) with bypass control over at least one of the ports (410) connected to the loop (406, 408). In the event of a failure on the first loop (406), the host means (402) instructs the bypassing of at least one port (410) on the first loop (406), the host means (402) sending the instructions via the control device (414, 440) on or connected to the second loop (408). The host means (402) may determine the physical topology of the ports (410) on the first and second loops (406, 408) such that when a failure is reported to the host means (402) by a port (432) on the first loop (406), the host means (402) instructs the bypassing of a port (434) in a specific relationship to the reporting port (432) on the first loop (434). The host means (402) may instruct the bypassing of all ports (416) on the first loop (406) and subsequently selectively un-bypass ports (416) to ascertain the location of a faulty port or ports.

摘要： A method and apparatus are provided for fault location in a loop network (100, 200, 400). The network system having a host port (214) for supplying and receiving data and a plurality of successively connected ports (201, 202, 203, 204, 205) through which data from the host port (214) is transferred. A counter (122) for each port records data transfers in which the amount of data received at a destination port is less than an expected amount of data. When a transfer with less than the expected amount of data is identified for a data flow between a sending port (201) and a destination port (214), the counters are incremented for each port (202, 203, 204, 205, 214) after the sending port up to and including the destination port. Analysing means determines a fault location in the network system from the distribution of counts in the counters (122).

摘要： Described is a system and method of communicating between first and second nodes connected by a serial link wherein the data is transmitted between the nodes in the form of packets made up of multiple bit frames. Each packet that is correctly received by the second node is acknowledged by means of a pair of multibit frames. These frames may be interleaved among the frames making up any outgoing data packet that is being transmitted by the second node. The technique employed provides unambiguous acknowledgment of each data packet and if a data packet is received incorrectly, the packet is available in a buffer in the first node for resending.

摘要： A method and apparatus for recovery from faults in a loop network (500) is provided. The loop network (500) has a plurality of ports (520, 530, 532, 534) serially connected with means for bypassing the ports (520, 530, 532, 534) from the loop network (500). A control device (522, 524) is provided with bypass control over at least one of the ports (530, 532, 534). A host means (502) sends a command to the control device (522, 524) at regular intervals and the control device (522, 524) has a counter which restarts a time period at the receipt of each command. If the time period expires, the control device (522, 524) activates the means for bypassing all the ports (530, 532, 534) under its control. The loop network (500) may have two loops (516, 518) with at least some of the ports (520, 530, 532, 534) common to both loops (516, 518).

摘要： An error recovery method for use in an information communication system which comprises a plurality of nodes connected by links. Information is transferred between the nodes in frames of predefined types, including at least a first frame type used to transfer data and a second frame type used for error recovery. Each node has at least a first and a second mode of operation. In the first mode frames of both first and second types are accepted. In the second mode frames of the first type are discarded and only frames of the second type are accepted. A master node which controls error recovery is selected from amongst those nodes which can initiate transfers.
