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.

Content routing in digital communications networks

A method of managing a content routed network, involves distributing published documents through said network for delivery to subscribers; maintaining data logs pertaining to said published documents at different points in the network; and correlating the data logs to obtain information about the operation of the network.

Data logging in content routed networks

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.

Dynamic links in content-based networks

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.

Content router with multiple forwarding elements instantiated on hardware entities

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.

Implicit routing in content based networks

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.

Meta-tagging in content routed networks

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.
