摘要:
In accordance with the present invention, systems and methods for providing content-based instant messaging are provided, which allows users to send and receive messages based on whether the recipient fits the criteria specified by the content of the message. The system and method of the present invention identifies recipients by matching the content of the message to the interest, or expertise profile of the recipient. By enabling individuals to communicate with people that fulfill a certain criteria, it will enable the autonomous creation of communities of interest, and facilitate the identification of “experts” without the need to create a centralized expertise database.

A method, system and apparatus for routing data through a network based on the content or semantics of the data. Semantic routing engines route the data through the network based upon information maintained in routing tables. The routing tables used to route the content through the network are derived by aggregating information about either content consumers or content producers into ontological trees.

A system and method for providing cost-effective broadband mobile services using a hybrid wireless network consisting of wide-area cellular (“3G”) supplemented by hotspot caches are provided. The proposed architecture uses opportunistic access of high-bandwidth wireless hotspot to dramatically reduce the cost per MB of media delivered to mobile end-users. The system also uses a “semantic multicast routing” approach to caching and delivering media based on individual user profiles.

There is disclosed a decentralized flow control technique based on microeconomics. In this framework, there are three important entities: switches, network brokers and users. Switches independently price their resources to provide flow control and to encourage high utilization. A network broker, located at the entrance of the network, works as an agent for a user, monitoring the budget, prices and needs. Using this information the network broker may purchase resources to maximize the user's quality of service. This approach has several advantages such as: decentralized control, minimal signaling, Pareto-optimal resource distribution, price stability and high network utilization.

The present invention changes the wireless information service paradigm from a connection-oriented unicast network model to a dynamic content-driven multicast model using a technique called “content routing.” The present invention provides a system, method, and medium for routing content through a network from at least one content provider to at least one content consumer, wherein at least one of the content consumer or content provider communicate with the network using a wireless device. The content is routed though the network based on its content. The content is labeled with at least one content descriptor. The content descriptor characterizes or otherwise describes the content. Interest profiles are received from content consumers. Interest profiles from content consumers with a common network access point are aggregated into a single interest profile. Interest profiles can include more than the wireless consumers stated interest, such as for example, a content consumer's geographic location, the capabilities of the wireless terminal, type of service, policy preferences, and the like. Single interest profiles are shared across neighboring network access points to create a content routing table. Content, labeled with at least one descriptor, is routed through the network to content consumers based, in part, on content routing tables created from wireless content consumers'profiles.

A luminescent material, such as phosphor, is radiated by energy propagated from the side of an optical fiber, causing the luminescent material to emit visible light. The luminescent material can be of: a coincidentally-excited type, requiring the absorption of two wavelengths of radiation to emit visible light; memory-type, requiring absorption of one wavelength of charging radiation and absorption of another wavelength of controlling radiation to emit visible light; and quenchable type, requiring absorption of one wavelength of radiation to emit visible light and absorption of another wavelength of radiation to stop, i.e. quench, the emission of visible light. Two side-emitting optical fibers can be used, with each optical fiber providing one of the needed radiation wavelengths. One embodiment of the invention involves a matrix of optical fibers forming an optical display panel made using coincidentally-excited phosphors. Side-emitting optical fibers are used to simultaneously stimulate a phosphor pixel located between the two fibers, allowing matrix addressing of each pixel individually. The optical display panel is constructed of only optical components.

摘要:
The present invention is built upon an active network framework and an ontology-based information hierarchy, and, in addition to the features found in current network models, it provides a symmetrical framework for information filtering and binding in the network. Queries from information requesters are directly routed to relevant information sources and contents from information providers are distributed to the destinations that expressed an interest in the information. The query packets and content packets can carry commands that are executed at the active network nodes encountered by the packets as they traverse the network.
