Apparatuses, methods, and systems are disclosed for power headroom report generation. One method includes aggregating multiple serving cells. The method includes determining that a power headroom report is triggered. The method includes determining that an uplink resource for a new transmission on a serving cell of the multiple serving cells is allocated at a first time after the power headroom report is triggered. The method includes determining a power headroom value for each serving cell of the multiple serving cells being activated based on information received prior to and including a predetermined time before the start of the uplink resource at the first time. The method includes generating a power headroom report medium access control control element including at least the power headroom value for each serving cell of the multiple serving cells being activated.

A system including a server and a wireless RF access node connected to a communication network is provided. The server provides a first publish-subscribe broker of one or more publish-subscribe brokers forming part of a publish-subscribe broker network. The server connects to the wireless RF access node. A first entity connects via the wireless RF access node to the first publish-subscribe broker using a unicast IP address and thereafter publishes data packets. A second entity connects to the publish-subscribe broker network via any of the one or more publish-subscribe brokers. The server provides packet distribution services via the first publish-subscribe broker for the first entity, the publish-subscribe broker network routes communications from the first entity to the second entity when the second entity is subscribed; and the data packets published by the first entity are routed through the publish-subscribe broker to which the second entity is connected.

Systems and methods include a hypervisor for access points, edge nodes, and other network elements to facilitate use of and compatibility with shared access systems.

A plurality of data output apparatuses (10) are installed at places different from each other, and each output data in wireless communication. A data storage apparatus (20) stores the data output from the data output apparatus (10). The data output apparatus (10) includes at least one sensor and a wireless communication apparatus. The wireless communication apparatus stores, for each of the plurality of other wireless communication apparatuses that can be a transmission destination of the data, connection information for connecting to the other wireless communication apparatus and priority information indicating a priority of the other wireless communication apparatus. Then, the wireless communication apparatus repeats processing of reading the connection information, and performing communication by using the read connection information in descending order of the priority until the communication succeeds when a transmission route of the data is set.

This application provides a traffic analysis method and apparatus, and a computer system. The method includes: obtaining a plaintext feature and a ciphertext feature of a packet in traffic, where the ciphertext feature includes a length feature of an encrypted field in the packet; and analyzing the traffic based on the plaintext feature and the ciphertext feature, to identify a service or an application to which the traffic belongs. The method may be used for service identification or application identification. The ciphertext feature is introduced in traffic analysis, so that traffic identification accuracy is improved in a packet encryption scenario. In addition, this application further provides a common service traffic attribution method and apparatus, and a computer system.

A system for exchanging data in an aircraft between at least two on-board devices which are interconnected by a communication link clocked at a predetermined link frequency, a first device being configured so as to: acquire measuring signals at frequencies native to the measuring signals; create frames on the basis of the measuring signals according to the native frequencies; and transmit the frames at the predetermined link frequency to a second device via the communication link.

A thermoelectric generator transmitter includes: a hollow exterior frame having open ends; a heat-receiving plate covering one of the open ends of the exterior frame; a columnar member standing on the heat-receiving plate; a thermoelectric generation module arranged for facilitating heat transfer between the columnar member and the thermoelectric generation module; a radiator plate covering a part of the other one of the open ends of the exterior frame, the part corresponding to a location of the thermoelectric generation module; a processor drivable by electricity generated by the thermoelectric generation module and capable of outputting a detection signal detected by a sensor to an external device; and a terminal that receives the detection signal of the sensor from the external device. An inside of the exterior frame is divided into a location of the thermoelectric generation module and the processor and a location of the terminal.

A method for cooperative active-standby failover between service routers based on health of services configured on the service routers is presented. In an embodiment, a method comprises determining, by a first service router (“SR”) of a SR cluster, a plurality of aggregate score values for a plurality of SRs of the SR clusters. The SR cluster comprises the first SR which is active, and a second SR. An aggregate score value, of the plurality of aggregate score values, indicates health of one or more services configured on a SR. The method further comprises determining, based on the plurality of aggregate score values, whether the first SR, of the SR cluster, is healthier than the second SR. In response to determining that the first SR is healthier than the second SR, the first SR continues to operate in the active mode; otherwise, the first SR switches to a standby mode.
