摘要： The present invention is directed to a publish/subscribe system containing a plurality of brokers, a plurality of subscribers and plurality of brokers including publisher connecting brokers, intermediate brokers and subscriber connecting brokers. Subscriptions are introduced into the system by the subscribers through associated subscription brokers. New subscriptions are aggregated, assigned a virtual start time and propagated through the system toward the publishers. Each broker maintains subscription information in the form of a directed acyclic graph and a broker vector. Messages are published through the system by the publishers through their associated publisher connecting brokers. Each message is assigned a message vector associating subscriptions to that message. The published messages are routed through the brokers toward the subscribers in accordance with comparisons of message brokers and vector brokers conducted at each broker.

摘要： A content-based publish/subscribe system for providing gapless message delivery from a publishing client to a subscribing client, the system includes a plurality of brokers operatively coupled to one another via a network. Each of the brokers include at least one processor and are configured as a publisher-hosting broker, a subscriber-hosting broker or an intermediate broker. The subscriber-hosting broker is operatively coupled to the publisher-hosting broker via the network through the intermediate broker. At least a portion of the plurality of brokers are configured so as to eliminate a need for persistent storage of messages at the intermediate broker and to substantially guarantee a gapless delivery of one or more messages transmitted by the publishing client to the subscribing client, even in the presence of a failure in the publish/subscribe system.

摘要： A system and method for latency assignment in a system having shared resources for performing jobs including computing a new resource price at each resource and sending the new resource price to a task controller in a task path that has at least one job running in the task path. A path price is computed for each task path of the task controller, if there is a critical time specified for the task. New deadlines are determined for the resources in a task path based on the resource price and the path price. The new deadlines are sent to the resources where the at least one job is running to improve system performance.

摘要： A system and method for temporal synchronization of media streams in multimedia collaborative applications (i.e., a multi-user distributed applications used for interaction, both in the synchronous and asynchronous fashion among a group of users) in a wide-area distributed environment. The invention presents two abstractions; event streams and collaboration space, that together provide for coarse-grained temporal synchronization by using separate streams for different media and synchronizing the streams at the client location. VCR-like controls are also provided on groups of components in a collaborative application. The event stream provides many services such as replication, persistence, buffering, reading, and writing to archive. By implementing simple interfaces, existing collaborative applications, media players, and encoders become components that can be used to build complex multimedia collaborative applications. To efficiently implement a seeking function on a data component, the present invention introduces a framework for application-specific updates to a component state.
摘要翻译：用于在广域分布式环境中的多媒体协作应用程序（即，用于一组用户中的同步和异步方式中的交互的多用户分布式应用程序）中的媒体流的时间同步的系统和方法。本发明提出了两个抽象; 事件流和协作空间，它们通过为不同媒体使用单独的流并在客户端位置同步流来共同提供粗粒度的时间同步。在协作应用程序中的组件组中也提供类似VCR的控件。事件流提供许多服务，如复制，持久性，缓冲，读取和写入到归档。通过实现简单的接口，现有的协作应用程序，媒体播放器和编码器成为可用于构建复杂多媒体协作应用程序的组件。为了有效地实现对数据组件的寻求功能，本发明引入了用于组件状态的应用特定更新的框架。
