摘要： Methods and systems are described to store state used to forward multicast traffic. The system includes a receiving module to receive request to add a first node to a membership tree. The membership tree includes a first plurality of nodes associated with a multicast group. The system further includes a processing module to identify a second node in the first plurality of nodes and to communicate a node identifier that identifies the first node over a network to the second node. The node identifier is to be stored at the second node to add the first node to the membership tree. The node identifier is further to be stored in the membership tree exclusively at the second node to enable the second node to forward the multicast traffic to the first node.

摘要： A method and system are described to multicast with an adaptive dual state. The system receives multicast traffic over a membership tree including a first plurality of nodes connected in a first topology destined for a plurality of multicast members of a first multicast group. Next, the system determines a rate of multicast traffic that exceeds a predetermined threshold based on the receiving the multicast traffic. Next, the system generates a dissemination tree including a second plurality of nodes connected in a second topology to reduce a number of hops to communicate the multicast traffic to the plurality of multicast members of the first multicast group. Finally, the system forwards the multicast traffic to the plurality of multicast members of the first multicast group over the dissemination tree.

摘要： Distribution of content between publishers and consumers is accomplished using an overlay network that may make use of XML language to facilitate content identification. The overlay network includes a plurality of routers that may be in communication with each other and the publishers and consumers on the Internet. Content and queries are identified by content descriptors that are routed from the originator to a nearest router in the overlay network. The nearest router, for each unique content descriptor, generates a hash identification of the content descriptor which is used by remaining routers in the overlay network to provide the appropriate functions with respect to the content descriptor. In particular, this allows all routers in the overlay network except the nearest router to properly route content without processing every content descriptor.

摘要： A vast amount of information currently accessible over the Web, and in corporate networks, is stored in a variety of databases, and is being exported as XML data. However, querying this totality of information in a declarative and timely fashion is problematic because this set of databases is dynamic, and a common schema is difficult to maintain. The present invention provides a solution to the problem of issuing declarative, ad hoc XPath queries against such a dynamic collection of XML databases, and receiving timely answers. There is proposed a decentralized architectures, under the open and the agreement cooperation models between a set of sites, for processing queries and updates to XML data. Each site consists of XML data nodes. (which export their data as XML, and also pose queries) and one XML router node (which manages the query and update interactions between sites). The architectures differ in the degree of knowledge individual router nodes have about data nodes containing specific XML data. There is therefore provided a method for accessing data over a wide area network comprising: providing a decentralized architecture comprising a plurality of data nodes each having a database, a query processor and a path index, and a plurality of router nodes each having a routing state, maintaining a routing state in each of the router nodes, broadcasting routing state updates from each of the databases to the router nodes, routing path queries to each of the databases by accessing the routing state.
摘要翻译：目前可以通过Web和企业网络访问的大量信息存储在各种数据库中，并作为XML数据导出。然而，以声明和及时的方式查询这些信息是有问题的，因为这组数据库是动态的，并且常见的模式很难维护。本发明提供了解决针对XML数据库的这种动态集合发出声明性特征XPath查询并及时接收答案的问题的解决方案。提出了一种分散架构，在一组网站之间的开放协议合作模式下，用于处理查询和更新XML数据。每个站点由XML数据节点组成。（它们以XML格式导出数据，并提供查询）和一个XML路由器节点（管理查询和更新站点之间的交互）。各种路由器节点对包含特定XML数据的数据节点的知识程度不同。因此，提供了一种用于通过广域网访问数据的方法，包括：提供分散式架构，其包括多个数据节点，每个数据节点具有数据库，查询处理器和路径索引，以及多个路由器节点，每个节点具有路由状态在每个路由器节点中保持路由状态，从每个数据库向路由器节点广播路由状态更新，通过访问路由状态将路由查询路由到每个数据库。
