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

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.

Coding of routing protocol messages in markup language

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.
