摘要： A method and apparatus for determining common usage of elements among at least two channels in a data processing system having an arbitrary hardware element hierarchy including multiple channel paths over which data is transmitted. An internally executed initialization program builds a bit mask for channel paths to be compared wherein the bit masks describe the hierarchy of the hardware elements in the channel paths to be compared. A compare program provides a comparison result whose value reflects the impact of the failure of hardware elements that are common to the channel path being compared. The comparison results contains multiple bits, with set bits representing each element which is common to the hardware element common to the channel paths being compared. The impact of a failure of a common hardware element is greater the more significant the bit position of that component resides in the comparison results.

摘要： A disk drive operative to reduce squeeze hard error is described. In response to a write fault (404) indicating that data has been inadvertently written to some portion of a track adjacent to an intended track, track overshoot is determined (416) based on a position error signal (PES) and pre-stored head width data. If the track overshoot exceeds a threshold (418), data from the adjacent track is read and rewritten (422) to remove the overshoot interference. Preferably, the reading and rewriting is performed during an idle mode immediately following the write fault using previously stored addresses.

摘要： A hit-less cell switching device capable of switching ATM (Asynchronous Transfer Mode) cells between a system ZERO and a system ONE is disclosed. The system ZERO includes a first cell switch, a first input cell gate, a first output cell gate, and a first shaper. Likewise, the system ONE includes a second cell switch, a second input cell gate, a second output cell gate, and a second shaper. First, a controller opens the first and second input cell gates and first output cell gate, closes the second output cell gate, and puts the first and second cell switches and first and second shapers in a fully switched condition, thereby initializing the switching device. Subsequently, the controller closes the second input cell gate, evacuates queue buffers included in the second cell switch and second shaper, and opens the second output gate. After putting the two cell switches and two shapers in an in-switching state, the controller closes the first input cell gate and opens the second input cell gate simultaneously. When the first cell switch and first shaper are evacuated and the arrival of cells ends, the controller causes the second cell switch and second shaper to read cells out of their queue buffers, respectively. On confirming the end of switching of the first cell switch and first shaper, the controller closes the first output cell gate and opens the first input cell gate, thereby completing switching from the system ZERO to the system ONE.

摘要： The invention provides for a method for transporting a SONET formatted asynchronous transfer mode (ATM) signal and/or a synchronous transfer mode (STM) signal on a line switched ring over a unidirectional path. The SONET formatted ATM signal comprises cells mapped into a STS-Mc or m×STS-1s while the STM signal comprises STS-1s/VTs mapped STS-W. A unidirectional line switched ring is provided for transporting the STM STS-W using a unidirectional path switched protection protocol and the ATM STS-Mc using a unidirectional line switched protection protocol. A ring node comprises input and output ring interfaces, an STS management block, an ATM cell management block, and a non-ATM payload management block. The STS management block routes the traffic to the ATM cell management block and to the non-ATM payload management block, according to the traffic type. The STS management block also provides the UPSR protection for the STS-1s and ULSR protection for the STS-Mc. The ATM cell management block maps the add ATM cells received from the ATM ports into the STS-Mc signal, and delineates the cells from the STS-Mc to present them to the ATM ports. The non-ATM payload management block routes STM VTs or STS-1s to/from the non-ATM ports.

摘要： The architecture of the Smart Test is described. Instead of writing a script, the Tester designs a functional model of the system to be tested, such as an application. For example, the Tester would model the functions of the system to be tested, such as a main window, a menu bar, drop-down menus, specialized windows etc. The more complete the model, the better the chance testing will cover existing function. The Tester would also define any facts that the model might need (for example, the name of the file to be opened and saved). The Tester then defines any goals or subgoals to be attained. A goal might be saving the file. Then the rules under which the model will operate are defined. One rule might be if the file (named as a fact) has its date and/or time changed, then the goal of saving the file was reached and the test will end.

摘要： A client station on computer network uses an operating system such as JavaOS which is permanently stored at the server rather than on storage media at the client location. JavaOS is loaded and installed at the client upon bootup of the client. Java is an interpreted language; the source is available at the server and is downloaded as such. Upon the occurrence of a malfunction that causes the client to go off-line, i.e., disappear from the network, a dump image is sent to the server before the client reboots, so that the cause of failure can be determined. The dump image includes the contents of memory, including the JavaOS operating system, and the stack, threads, registers, and local/global variables, which can be analyzed at a source level. This image is sent to the server in formatted packets, by a path separate from that of the TCP/IP network protocol, since the client would not be functioning properly on the network. At the server, the packets making up the dump image are stored on storage media, and the image is reformatted for use by a standard debugging tool, ICAT.
摘要翻译：计算机网络上的客户端站使用诸如JavaOS的操作系统，该操作系统永久存储在服务器而不是存储在客户端的存储介质上。 JavaOS在客户端启动时被加载并安装在客户端。 Java是一种解释语言; 源在服务器上可用，并且这样下载。当出现导致客户端离线的故障，即从网络消失时，在客户端重新启动之前，将转储映像发送到服务器，从而可以确定故障原因。转储映像包括内存的内容，包括JavaOS操作系统，以及可以在源级别分析的堆栈，线程，寄存器和本地/全局变量。通过与TCP / IP网络协议的路径分开的路径，此映像以格式化的数据包发送到服务器，因为客户端在网络上将无法正常运行。在服务器上，构成转储映像的数据包存储在存储介质上，重新格式化映像，以供标准调试工具ICAT使用。

摘要： A fault tolerant switching architecture is provided with two separate switch fabrics each having a switch cure located in a centralized building and a set of SCAL elements distributed in different physical areas. Each SCAL element has both a SCAL receive element and a SCAL transmit element for access to a corresponding input and output port of the swatch core. A set of port adapters is distributed at different physical areas, with each connected switch fabrics via a particular SCAL element so that each switch core receives the sequence of cells coming from any port adapter and conversely any port adapter may receive cells from either one of the switch cores. Each switch fabric can detect an internal breakdown condition occurring in one of its element and send an error control signal to the peer element located in the other switch fabric. Each switch core extracts the Switch Routing Header (SRH) from the cells entering the switch core, and a routing table for obtaining a bit map value that indicates the output ports to which the cell should be routed. An additional controllable masking mechanism is used for altering the value of the bit map in response to the detection of the error control signal from the peer switch core. The routing process is then performed with the altered value of the bitmap.

摘要： This invention is to record data and skip an ECC block containing a defective sector when the defective sector is detected in an optical disk in which data is recorded in an ECC block unit constructed by 16 sectors and record a physical block number obtained by adding an amount of 16 sectors for each skipping into a reserve field of each sector of a next ECC block. Thus, continuous data such as moving pictures can be recorded in the ECC block unit, an ECC block containing the defective sector can be detected later in a case wherein the power supply is turned OFF by mistake or power failure in the course of recording when the recording process is effected while skipping an ECC block containing a defective sector, and data recorded up to the interruption can be reproduced without being influenced by the defective sector.
