    • Techniques are provided for representing and managing data and associated relationships. In one aspect of the invention, a technique for managing data associated with a given domain comprises the following steps. A specification of data attributes representing one or more types of data to be managed is maintained. Further, a specification of algorithms representing one or more types of operations performable in accordance with the data attributes is maintained. Still further, a specification of relationships representing relationships between the data attributes and the algorithms is maintained. The data attribute specification, the algorithm specification and the relationship specification are maintained in a storage framework having multiple levels, the multiple levels being specified based on the given domain with which the data being managed is associated. The techniques may be provided in support of service level management. In such a domain, the present invention provides techniques for representing and managing service level agreement management data using a multi-level multi-ontology metadata store and extensible service level management framework.
    • 提供技术来表示和管理数据和关联关系。 在本发明的一个方面,一种用于管理与给定域相关联的数据的技术包括以下步骤。 维护表示要管理的一种或多种类型的数据的数据属性的规范。 此外,保持表示根据数据属性可执行的一种或多种类型的操作的算法的规范。 此外,维持表示数据属性和算法之间的关系的关系的规范。 数据属性规范,算法规范和关系规范被保存在具有多个级别的存储框架中,所述多个级别是基于与被管理数据相关联的给定域来指定的。 可以提供技术来支持服务水平管理。 在这样的领域中,本发明提供了使用多级多本体元数据存储和可扩展服务级别管理框架来表示和管理服务级别协议管理数据的技术。

    • A system, method, and computer program product for establishing multi-party VoIP conference audio calls in a distributed, peer-to-peer network where any number of nodes are able to arbitrarily and asynchronously start or stop producing audio output to be mixed into a single composite audio stream that is distributed to all nodes. A single distribution tree is used that has optimal communications characteristics to distribute the composite audio signal to all nodes. An audio mixing tree is established and maintained by adaptively and dynamically adding and merging intermediate mixing nodes operating between user nodes and the root of the single distribution tree. The intermediate mixing nodes and the root of the single distribution tree are all hosted, in an exemplary embodiment, on user nodes that are endpoints of the distribution tree.
    • 一种用于在分布式对等网络中建立多方VoIP会议音频呼叫的系统,方法和计算机程序产品,其中任何数量的节点能够任意地和异步地开始或停止产生混合到 单个复合音频流分配给所有节点。 使用具有最佳通信特性以将复合音频信号分配给所有节点的单个分发树。 通过自适应地动态地添加和合并在用户节点和单个分发树的根之间运行的中间混合节点来建立和维护音频混合树。 在示例性实施例中,分发树的中间混合节点和根分别在作为分发树的端点的用户节点上托管。
