    • Methods and apparatus are described for translating identifiers that are used by computers to reference various entities such as data structures, external objects, or connections in a telecommunications network, from a bulkier less manageable format to a smaller more manageable format. Such translations are carried out to reduce the needless processing and memory demands that are made of a localized set of components when the large identifiers the set receives from other components include fields that none of the members of the set need to access. The invention is centerd around a two-stage look-up method wherein an inputted external identifier is divided into two parts. The first part of the inputted external identifier is used as an address into a first look-up table that contains base-addresses of a second look-up table. The second part of the inputted external identifier is used as an offset-address into the second look-up table. The offset-address and the base-address are combined to access the second look-up table, which contains all the internal identifiers. The invention can be easily scaled to handle a larger range of external identifiers, and a larger number of internal identifiers. The invention operates at a fast and predictable speed. Use of the invention also leads to a significant savings in memory costs.
    • 描述了用于翻译计算机使用的标识符的方法和装置,以引用各种实体,例如电信网络中的数据结构,外部对象或连接,从庞大的较不易管理的格式到更小的更易于管理的格式。 执行这样的翻译以减少当集合从其他组件接收到的大标识符包括集合中的任何成员都不需要访问的字段时,由本地化的组件集合形成的不必要的处理和存储器需求。 本发明围绕两阶段查找方法,其中输入的外部标识符被分成两部分。 输入的外部标识符的第一部分用作包含第二查找表的基地址的第一查找表中的地址。 输入的外部标识符的第二部分用作第二查找表中的偏移地址。 偏移地址和基地址被组合以访问包含所有内部标识符的第二查找表。 本发明可以容易地缩放以处理更大范围的外部标识符和更大数量的内部标识符。 本发明以快速且可预测的速度运行。 使用本发明还可显着节省存储器成本。

    • Described herein is a system for executing distributed transactions. A coordinator and one or more participants cooperate to execute a distributed transaction, the distributed transaction including for each participant a transaction executed by the participant. To manage the transaction, the coordinator and the participant communicate over a network using, for example, a stateless protocol. Before each participant commits the transaction, the participants determine that the coordinator has committed the transaction. The coordinator commits the transaction after receiving acknowledgment from all the participants that they will commit the transaction. To determine whether the coordinator has committed the transaction, a participant transmits a message to the coordinator to acknowledge that it will commit the distributed transaction. The participant commits its respective transaction if it receives an acknowledgement from the coordinator. For the particular transaction being executed by a participant, the participant prevents other transactions from modifying a data item affected by the particular transaction. The participant will prevent such modifications until termination criteria for the particular transaction is satisfied, in which case the participant terminates the transaction.
    • 这里描述了一种用于执行分布式事务的系统。 协调者和一个或多个参与者合作执行分布式事务,所述分布式事务包括每个参与者参与者执行的事务。 为了管理事务,协调者和参与者通过使用例如无状态协议的网络进行通信。 在每个参与者提交交易之前,参与者确定协调者已经提交了交易。 协调人在收到所有参与者确认交易之后提交交易。 为了确定协调者是否已经提交了交易,参与者向协调者发送消息以确认它将提交分布式事务。 参与者如果收到协调员的确认,则提交其各自的交易。 对于由参与者执行的特定交易,参与者阻止其他交易修改受特定交易影响的数据项。 参与者将防止此类修改,直到满足特定交易的终止条件为止,在此情况下,参与者终止交易。
