A system in which data signatures are used to identify copyrighted content passing through a network. The data signatures are derived from files containing copyrighted content to be identified. The signatures are used to search within peer-to-peer data streams flowing through one or more network nodes in a communications network. Any specific technique may be used for pattern recognition between the signatures and the monitored traffic. When a particular file of interest is identified, the system may operate to perform one or more of several possible actions, including stopping the transmission, allowing the transmission but recording the event, making an offer to the recipient allowing them to legally purchase the file, or sending alternative information or intentionally corrupting the information to render it useless to the recipient.

Method and system for content detection and interception in communication networks

A telecommunication station set such as an IP phone is configured based on proximity of a user. Proximity of the user relative to the station set can be determined using RF-ID, UWB, GPS, direct user input, contextual information or other technology. For example, the user may carry a badge equipped with an RF-ID tag. The RF-ID tag is operative in response to an RF-ID reader associated with the phone, when in close proximity, to signal user ID and password, which may be encrypted. The user ID and password are sent to a SIP server, which authenticates the user and retrieves user-specific configuration details which are returned to the IP phone. The IP phone configures itself with the user-specific parameters. If the user moves away from the phone, as determined by the RF-ID tag being out of range of the reader, the IP phone de-configures itself.

Automatic configuration of telecommunication station sets

Documents written using a markup language such as XML may be decomposed into Path and Parent Associated Node (PPAN) elements, each of which is a linear data structure that includes the content of a node, the parent-child relationship of the node, and the path level of the node. A number of PPAN elements may be grouped together to form A PPAN chain. A PPAN matching process uses the PPAN elements/PPAN chain to search for structured documents that match the PPAN chain. The PPAN matching process is able to perform query and match at the same time to accelerate the PPAN matching process, and also enables complex services to be represented by generic structured documents. Optionally, the PPAN matching process may support wildcard requests so that services may be discovered without prior knowledge of the services.

In response to a network topology change, a clock root node calculates a new clock path for each affected node by building a clock source topology tree, and identifying from that tree a path to the network node from a clock source of higher or equal stratum relative to that network node. The root node then sends a network message to each node indicating the new path that the node should use. Each node receives the message and compares the new path with the existing path. If the paths are different then the node acquires the new path just received in the message. If the paths are the same then the node does nothing and discards the message.

Protocol for clock distribution and loop resolution

A method of determining whether to set up a delay-sensitive communication session over an internet protocol (IP) based network includes sharing link state information among the network nodes of the link state protocol controlled network, receiving an IP packet that conveys a request to set up a delay-sensitive communication session over the network; determining, based on the shared link state information, a shortest path through the link state protocol controlled network for the requested delay-sensitive communication session and whether the shortest path is deemed suitable for the delay-sensitive communication session, and setting up the delay-sensitive communication session over the shortest path only when the shortest path is deemed suitable for the delay-sensitive communication session.

A method and system for monitoring context information associated with a wireless communication entity for determining a potential occurrence of a network disruption for that wireless communication entity. Upon determining a potential occurrence of a network disruption, causing an adjustment of bandwidth available for data transfer involving the wireless communication entity. The adjustment is used to prevent or mitigate service disruptions.

Method and system for reducing service interruptions to mobile communication devices

System and method for determining location-enhanced presence information for a particular entity subscribed to a communications system. Location information indicative of a current location for the particular entity is obtained, as well as presence information indicative of a current activity status of the particular entity within the communications system. A combination of the current location and current activity status of the particular entity is applied as a condition to a set of conditional rules associated with the particular entity, for determining current location-enhanced presence information for the particular entity.

Secure access to inventory data concerning a supplier's product located at a seller's premises is provided by tagging units of product with a supplier identifier and a product identifier. The identifiers may be embedded in RFID tags or EPC labels. A secure VPN tunnel is established between a supplier and a seller. The VPN tunnel is associated with a particular supplier identifier such that only inventory data associated with the supplier identifier that matches the supplier is transmitted on the VPN tunnel, and inventory data associated with supplier identifiers that do not match the supplier are filtered out. Hence, the seller can provide the supplier with access to inventory data without exposing sensitive information related to the seller and other suppliers.

Secure, differentiated reading of sensors and RFID tags

Described are a method and system for determining whether to establish a call over an internet protocol (IP)-based network. A network device inspects an IP packet to determine that the IP packet conveys a message to initiate a call. The network device determines a shortest path through a link-state network to be taken by traffic associated with the call if the call is admitted. The network device also determines whether each link in the shortest path through the link-state network is available for supporting the traffic associated with the call and issues a message that rejects admission of the call if at least one link in the shortest path through the link-state network is unavailable for supporting the traffic associated with the call.

A technique for transmitting an optical signal along an optical wavelength path through an optical network having a plurality of network nodes is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for transmitting an optical signal along an optical wavelength path through an optical network having a plurality of network nodes. Such a method may comprise transmitting a first message from a first node to a second node requesting an optical wavelength path from the first node to at least the second node, and simultaneously configuring the first node for transmitting an optical signal along the optical wavelength path from the first node to the second node.

A method and apparatus for communicating wireless network landscape information to a mobile device is shown and described. Strategic placement of beaconing devices that are encoded with pre-defined, specialized SSIDs allows information to be forwarded to the mobile clients to trigger specific behavior in the clients and to enable the clients to pro-actively control network transitions, thereby increasing their ability to provide seamless communications.

A traffic controller is provided which integrates black-box tests of unauthorized applications to extract application characteristics from associated Internet traffic, exploits the networking information learned by host clients, actively scans and controls hosts on the corporate network, and dynamically configures a corporate firewall to block traffic to and from critical application network elements. As a result, the traffic controller effectively manages unauthorized applications and their associated traffic in a corporate environment.
