摘要： Reconfiguration of a continuously available routing network of a publish/subscribe system is achieved by quiescing data messages and control messages within the routing network to preserve first-in first-out ordering thereof, and then, reconfiguring the quiesced routing network. This reconfiguration technique is particularly applicable to a routing network having at least one special node comprising one of a logger node or a sequencer node, wherein the logger node is used to store a message to persistent storage within the routing network prior to delivery of the message to one or more clients, and the sequencer sequences a message with other messages received by the network prior to delivery thereof for ordered delivery of the messages to one or more clients of the network.

摘要： A scalable merge technique for information retrieval across a distributed network is provided, as well as a fault tolerant technique for communicating information across the distributed network. The merge technique includes multicasting a query request across a spanning tree of the distributed network from a root node to multiple clients of the tree, and receiving back at the root node, a merged response produced from responses from at least some of the clients of the spanning tree. The fault tolerant technique for communicating information across the distributed network includes assigning a unique identifier to each query request, automatically reconfiguring the network upon detection of a failure of a node of the network, and retransmitting the query request and/or any responses thereto within the reconfigured network.

摘要： A technique for reliably multicasting a message within a router network in a sequenced order with other messages is provided. At least one special router in the network has associated persistent storage for sequencing a message being routed to one or more clients. When a message is received at this sequencer node, the sequencer places a sequence number for the message in persistent storage and sends a sequencing acknowledgment back to those routers to which the message was originally routed, as well as back towards the source of the message. The sequencer acknowledgment includes the message id, and the sequencing number. When the sequencer acknowledgment is received by a router, it looks up the routing information from the original message, and sends the acknowledgment to those neighboring routers to which the original message was sent, excluding the link from which the sequencer acknowledgment was received. If the original message corresponding to the sequencer acknowledgment was buffered at this router waiting to be delivered, the message is then delivered to its client nodes.
摘要翻译：提供了一种以其他消息的顺序可靠地组播路由器网络内的消息的技术。网络中至少有一个特殊路由器具有关联的持久存储器，用于对正在路由到一个或多个客户端的消息进行排序。当在该定序器节点处接收到消息时，定序器将消息的序列号放置在持久存储器中，并将排序确认发送回消息最初路由到的那些路由器，以及返回到消息的源。定序器确认包括消息标识和序列号。当定序器确认由路由器接收时，它从原始消息中查找路由信息，并将确认发送给发送了原始消息的相邻路由器，不包括接收定序器确认的链路。如果在等待传递的路由器上缓冲对应于定序器确认的原始消息，则将该消息传递给其客户机节点。

摘要： A router within a network uses the data of a message received at the router to determine on which links out of the router the message needs to be forwarded. The router does not need any destination information from the message, and thus, the message need not include any destination information. Instead, the router uses an annotated search data structure to determine which links correspond to consumers interested in receiving the message. The message is sent only over those links.
摘要翻译：网络内的路由器使用在路由器接收到的消息的数据来确定路由器哪个链路需要转发该消息。路由器不需要来自消息的任何目的地信息，因此，该消息不需要包括任何目的地信息。相反，路由器使用带注释的搜索数据结构来确定哪些链接对应于对接收消息感兴趣的消费者。该消息仅通过这些链接发送。

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 technique for reliably multicasting a message within a router network is provided. At least one special router in the network has associated persistent storage for logging a message being routed to one or more clients. When a message is received at this logger node, the logger places the message in persistent storage and sends a logging acknowledgment back to those routers to which the message was originally routed, as well as back towards the source of the message. The logger acknowledgment includes the message id, the logger id, and a logging number. When the logger acknowledgment is received by a router, it looks up the routing information from the original message, and sends the acknowledgment to those neighboring routers to which the original message was sent, excluding the link from which the logger acknowledgment was received. If the original message corresponding to the logger acknowledgment was buffered at this router waiting to be delivered, the message is then delivered to its client nodes. Processes for recovering from node or link failure within the router network, and for at most once delivery of messages, at least once delivery of messages, and exactly once delivery of messages are also provided.

摘要： A generalized search data structure is used to match consumers to events in event computing systems. The search data structure includes one or more paths from a root of the structure to one or more leaves of the structure. Each path has at least one level and each level corresponds to a filter attribute. The value of at least one filter attribute in at least one path is a don't care value indicating traversal of that path is guaranteed to proceed. In addition to following the path with the don't care value, one or more additional paths may also be followed. Thus, traversal of the search data structure may yield zero or more results, indicating that zero or more consumers match the specified event. Various optimizations of the search data structure are possible.
摘要翻译：广义搜索数据结构用于将消费者与事件计算系统中的事件相匹配。搜索数据结构包括从结构的根到结构的一个或多个叶的一个或多个路径。每个路径至少有一个级别，每个级别对应一个过滤器属性。至少一个路径中的至少一个过滤器属性的值是一个不关心的值，表示该路径的遍历被保证继续。除了遵循不关心值的路径之外，还可以遵循一个或多个附加路径。因此，搜索数据结构的遍历可以产生零个或多个结果，指示零个或多个消费者匹配指定的事件。搜索数据结构的各种优化是可能的。
