Abstract: Methods, systems and media are provided for turning large volumes of globally distributed data into actionable information by building a distributed semantic graph and maintaining such graph with up to date changes in data and client needs are provided. The semantic graph can be used to run subscriptions over interconnected semantic servers where each server can be capable of coupling to data sources, client applications and other semantic servers.

Abstract: 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.

Abstract: 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.

Abstract: A new concept of soft quality-of-service (soft-QoS) is developed that bridges the gap between the efficient provision of network-level QoS and the requirements of multimedia applications. Soft-QoS is defined by a satisfaction index (a number that rates users' perceptual quality) and a softness profile (a function that captures the robustness of multimedia applications to network congestion). Another aspect of this invention is a bandwidth allocation scheme for multimedia applications with soft-QoS requirements is presented. The implementation of the bandwidth allocation scheme on a network element realizes a soft-QoS controller. The controller uses the connections' softness profiles to compute a bandwidth allocation that maximizes the minimum satisfaction index of active connections.

Abstract: 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.
