    摘要： Systems and methods for providing e-business services based on security SLAs (service level agreements) in a hosted computing environment. More specifically, the systems and methods enable efficient enforcement of individualized security SLAs, wherein individualized SLA agreements are specified, mapped into security rules and continually monitored against system events via an efficient rule index to determine security violations and trigger proper actions.

    摘要： A method for computing n-dimensional decomposable image transformation using the 1D approach with constrained transpose memory provides a minimized rounding/truncation error. The method minimizes transpose memory size required to fulfill a defined accuracy requirement for n-dimensional image transformation. A set of input data elements are stored. Then, a first transform, of the multiple dimension transform, is performed on the set of input data elements so as to form an array of transformed data elements, each of the transformed data elements having a larger number of bits than the input data elements. A common range of the transformed data elements is determined, and a minimum number of bits required to represent the common range without loss of information is then determined. The memory word size available for storage of the transformed data elements is compared with a minimum number of bits so as to determine an excess number of bits. Only the excess number of bits of the transformed data is truncated/rounded so as to form an output set of data elements. Finally, the output set of data elements is stored.

    摘要： A data communications network includes network servers, clusters of network servers, as well as content providers and service providers, such as ISPs and ASPs, and further includes at least one data processor that operates under control of a stored program resident on a memory media. The stored program directs operation of the data processor to provide users with differentiated services by defining, for individual ones of the plurality of content providers, a plurality of levels of services for users, and for responding to service level tables received from individual ones of the plurality of content providers, where individual ones of users are assigned to one of the plurality of levels of service. There is also at least one resource requirement table for defining at least a minimum set of resources required for realizing individual ones of said plurality of service levels. The program further directs operation of the at least one data processor to merge the plurality of resource requirement tables into a merged resource requirement table for use by a particular one of the network servers. The particular one of the network servers assigns differentiated service levels to incoming user requests in accordance with the service level tables, and in accordance with the merged resource requirement tables and currently available resources. The resources can include one of numbers of available servers, available memory capacity, and available bandwidth. The program further controls operation of the at least one data processor to redirect an incoming user request to a network server having sufficient available resources to provide a specified level of service for the user request.

    摘要： This invention introduces a new concept called virtual construct intervals (VCI), where each predicate interval is decomposed into one or more of these construct intervals. These VCIs strictly cover the predicate interval. Namely, every attribute value covered by the predicate interval is also covered by at least one of the decomposed VCIs, and vice versa. Each construct interval has a unique ID or interval coordinate and a set of endpoints. A construct interval is considered activated when a predicate interval using it in its decomposition is added to the system. The predicate ID is then inserted into the ID lists associated with the decomposed VCIs. To facilitate fast search, a bitmap vector is used to indicate the activation of VCIs that cover an event value. The challenge is to find an appropriate set of construct intervals to make predicate decomposition simple and, more importantly, to build efficient bitmap indexes. Because each construct interval covers only a small range of attribute values, the invention also uses bitmap clipping to cut unnecessary bitmap storage. To facilitate bitmap clipping, the invention introduce the covering segment concept. Bit positions outside a covering segment are pruned.

    摘要翻译： 本发明引入了称为虚拟构建间隔（VCI）的新概念，其中每个谓词间隔被分解成这些构建间隔中的一个或多个。 这些VCI严格覆盖谓词间隔。 即，由谓词间隔覆盖的每个属性值也被分解的VCI中的至少一个覆盖，反之亦然。 每个构造间隔具有唯一的ID或间隔坐标和一组端点。 当在其分解中使用它的谓词间隔被添加到系统时，构造间隔被认为被激活。 然后将谓词ID插入到与分解的VCI相关联的ID列表中。 为了便于快速搜索，使用位图向量来指示覆盖事件值的VCI的激活。 挑战是找到适当的构造间隔集，使谓词分解变得简单，更重要的是构建有效的位图索引。 因为每个构造间隔仅覆盖一小段属性值，本发明还使用位图限幅来减少不必要的位图存储。 为了便于位图剪辑，本发明引入了覆盖段概念。 修剪覆盖段外的位位置。
