Abstract: A method of assigning a priority to a document in a content-routed network including a plurality of routers interconnected by links, involves matching rules against the content of a received document to assign a priority, mapping the priority onto an egress link, and mapping the egress links onto the interconnect network between content routers to achieve end-to-end quality of service.

Abstract: A method of propagating multicast subscription and routing information between routers in a network, and constructing forwarding tables in the routers, allowing providers of the data (the publishers), and the multicast recipients of the data (the subscribers) to be decoupled from and have no knowledge of one another. This is done without the need to maintain (Source Network, Published-Multicast-Group) State in the routers, for a highly scalable solution in those applications where there is a possibility for a large, or infinite number of Published-Multicast-Groups, and in those applications where messages are being routed by content, so it is impossible to identify published-multicast-groups.

Abstract: In a method of managing a content-based network including a plurality of content routers, such as XML routers, dynamic links are established between the content routers which are not direct neighbors.

Abstract: A carrier grade content router, includes a distinct management plane for housing externally visible management applications, and coordinating and relaying external management requests to appropriate underlying application code in the router; a distinct control plane for running control protocols required within an XML routed network; and a distinct data plane for receiving and forwarding customer data. Some functions can be implemented in software or via a hardware accelerator.

Abstract: In a method of managing a content-based network, which is typically XML-based, and optionally may be overlaid on an underlying network having a plurality of network elements interconnected by links, a link state protocol maintains each network element's topological view of the overlay network from the underlying network. A subscription management protocol ensures dissemination of published content within the content-based network independently of the link state protocol.

Abstract: A method of adding meta-data to document in a content-routed network including a plurality of routers interconnected by links involves adding an encoded meta-tag to the document.

Abstract: An implicit routing protocol for content-based networks having a plurality of XML routers includes an XML Link State Protocol and an XML Subscription Management Protocol that routes customer data based on XML content. The XML Link State Protocol and the XML Subscription Management Protocol includes several messages that must be exchanged between XML routers in the network. These messages are encoded using XML.

Abstract: A method for exchanging control and customer data between network element in a communications network involves establishing a virtual connection between the routers, and exchanging the control and customer data over an http layer.

Abstract: The Web Store Converter extracts information from an existing source, such as a web site, and translates that information into an immersive 3D environment characterized by a spatial visual representation of the data. The process is defined in two parts, the Web Store Crawler and the Web Store Builder. The Web Store Crawler is responsible for parsing data from the input source, refining the data, grouping it into departments, retrieving image files and generating the input for the Web Store Builder. The Web Store Builder is responsible for analyzing this data, designing the 3D rooms, connecting the rooms, filling the rooms with components and adding realistic styles to the 3D environment.
