摘要： A computing device operating according to a frequency division multiplexed protocol in which communication occurs over a signal formed from a plurality of sub-channels selected from anywhere in a frequency spectrum. A computing device may select sub-channels cognitively by using information about sub-channels previously deemed suitable or unsuitable by that computing device or other computing devices. A described technique for determining sub-channel suitability includes analyzing radio frequency energy in the sub-channel to detect signals generated by another computing device or high noise levels. Information may also be used to cognitively select sub-channels to be analyzed, such as by first selecting for analysis previously-used sub-channels.

摘要： In embodiments of the present disclosure systems and methods implementing active-hot standby redundancy in server architectures are described. In an active-hot standby redundancy architecture, two matching service instances are installed in a network on different host computers. A standby service instance may maintain state information for every session maintained at an active service instance that it is poised to replace using a publish-subscribe communications network. When a failure occurs in the active instance, the standby instance may promote itself to active, and assume all aspects of the service identity and role of the Active instance it is replacing. Service to user entities continues without interruption, although transactions that are ongoing just as the failure occurs may be lost.

摘要： An apparatus, configured to communicate with other apparatuses in a wireless network and operating in a frequency-division duplexing mode, can be caused to refrain from transmitting during a number of subframes of a frame of a downlink frequency band prior to a detection of a radar transmission, can be caused to send a first signal, related to monitoring for the radar transmission, to a second apparatus, and can be caused to change the number of the subframes of the frame of the downlink frequency band in response to an event that can be an increase or a decrease in a load of the apparatus or the detection of the radar transmission. Optionally, placement of the subframes within the frame of the downlink frequency band can correspond to placement of subframes that are designated for an uplink communication within a frame configured in accordance with the Long-Term Evolution Time-Division Duplex standard.

摘要： Some embodiments of the present invention provide middleware functionality integrated into a module of a network device, such as a router or switch, that is configured to provide application-oriented network (“AON”) services. Some preferred implementations of the invention provide policy-based application services for RFID data, such as conditional routing, security (encryption, identification, authentication and authorization), data translation and/or transformation, data compression, data caching, etc. Some preferred implementations can interpret an application request and route to an appropriate network address of an RFID reader. Preferably, ALE (application-level event) aggregation and filtering can also be performed on behalf of the application. Some methods of the invention allow event data to be sent to applications (including but not limited to business applications) as request-response messages. Other methods of the invention allow event data to be sent to applications in the form of asynchronous notifications.
