    • Methods and apparatus are provided for encoding data. The method includes (a) providing a first table of first component values multiplied by code generator coefficients and a second table of second component values multiplied by the code generator coefficients, (b) determining a Galois field element based on a message symbol and a high order remainder symbol, (c) separating the Galois field element into first and second components, (d) using the first component and a generator coefficient index to access one or more first table values in the first table and using the second component and the generator coefficient index to access one or more second table values in the second table, (e) determining a current remainder symbol based on first and second table values having equal generator coefficient indices, and a previous remainder symbol, (f) performing step (e) for each generator coefficient of the code generator to provide a set of remainder symbols, and (g) performing steps (b)-(f) for each message symbol in a codeword to provide a set of final remainder symbols which constitute check symbols to be transmitted with the message symbols of the codeword.
    • 提供了用于编码数据的方法和装置。 该方法包括:(a)提供与代码生成器系数相乘的第一分量值的第一表和乘以代码生成器系数的第二分量值的第二表,(b)基于消息符号和高的值来确定伽罗瓦域元素 (c)将伽罗瓦域元素分离为第一和第二分量,(d)使用第一分量和发生器系数索引来访问第一表中的一个或多个第一表值,并使用第二分量和发生器 系数索引以访问第二表中的一个或多个第二表值,(e)基于具有相等的生成器系数索引的第一和第二表值以及前一余数符号来确定当前余数符号,(f)执行步骤(e) 对于码发生器的每个发生器系数提供一组余数符号,以及(g)对于码字中的每个消息符号执行步骤(b) - (f)以提供一组 构成与码字的消息符号一起发送的检查符号的最后余数符号。

    • A system for aborting web services automatically and a method thereof are provided. In the system, an application program container has a first web service application program embedded, intercepts a message that is transmitted and received between a second web service program located externally and the first web service application program, identifies the kind of an operation requested by the second web service application program, and keeps information required for compensation. A protocol manager generates and manages a first sub-transaction object by a request of the second web service application program. A local compensator compensates the first sub-transaction if a global transaction coordinator that coordinates the state and success factor of a global transaction which is an upper-layer transaction of the generated first sub-transaction sends a command to compensate a second sub-transaction already committed. A protocol service unit transmits and receives messages for managing the first sub-transaction by communicating with the global transaction coordinator. A registration service unit registers the generated first sub-transaction with the global transaction coordinator.
    • 提供自动中止Web服务的系统及其方法。 在系统中,应用程序容器具有嵌入的第一web服务应用程序,拦截在位于外部的第二Web服务程序与第一Web服务应用程序之间发送和接收的消息,识别由 第二个Web服务应用程序,并保留需要补偿的信息。 协议管理器通过第二Web服务应用程序的请求生成和管理第一子事务对象。 如果全局事务协调器协调作为所生成的第一子事务的上层事务的全局事务的状态和成功因子的全局事务协调器,则本地补偿器补偿第一子事务,发送一个用于补偿第二子事务的命令 承诺 协议服务单元通过与全局事务协调器通信来发送和接收用于管理第一子事务的消息。 注册服务单元将生成的第一子事务与全局事务协调器进行注册。
