A solution for dynamic packet filtering includes, at a network device, if an n-tuple of a packet matches an n-tuple filter, applying an action of the filter to the packet. If the packet has not been discarded as a result of the filter application, and if the packet is identified, by using payload portion, as a network application associated with a filter policy, an n-tuple filter is generated based on the packet. If the application ID of the packet is not associated with a filter policy, the packet is forwarded to the network application.

A solution for rapid evaluation of numerically large complex rules governing network and application transactions includes, at a network device, receiving network transaction record comprising a plurality of elements that characterize a network transaction, creating a hash of a result of concatenating the plurality of elements, and if the hash is found in a hash table comprising, for each network transaction rule, a hash of the plurality of elements comprising the rule, blocking the network transaction or alerting a network user that a prohibited transaction has occurred.

Rapid evaluation of numerically large complex rules governing network and application transactions

A wireless headset and a system and method for controlling or managing a wireless headset are provided. In one embodiment, a wireless headset includes a World Wide Web (Web) server for providing a Web page to control or manage a headset, and a module operably coupled to the Web server for performing a control function or a management function on the headset. A communication device including a keypad, a display, and a Web browser can then exchange information between the Web page and the Web server to control or manage the wireless headset.

Control and management of a wired or wireless headset

The present invention is directed to providing frequency hopping medium access control among a plurality of nodes (e.g., communication stations) in a wireless communication system. The present invention is directed to decentralized control of synchronization among the plural nodes. In accordance with exemplary embodiments, a node used to control synchronization of the communication system can switch from a first master node to a second master node.

Frequency hopping medium access control protocol for a communication system having distributed synchronization

Access to a radio communications medium shared by at least two agents to provide peer-to-peer communication therebetween is controlled by sensing the communications medium at a first agent to determine if the communications medium is in use, transmitting from the first agent, if the first agent determines that the communications medium is not in use, a request-to-send message that includes reservation duration information, and receiving the request-to-sent message at a second agent. The second agent then transmits a clear-to-send message including reservation duration information on behalf of the first agent, after which the first agent then transmits information to the second agent while a reservation duration indicated by the reservation duration information has not elapsed. A possible third agent within receiving range of only one of the first and second agents is thereby guaranteed to receive the reservation duration information and is expected to observe the reservation according to rules disclosed.
