Abstract: Embodiments of the present invention provide an address management apparatus, system, and method for communication over the Multipath Transmission Control Protocol (MTCP). A processing module allocates a corresponding internet protocol (IP) address to each MPTCP session, where the MPTCP session is an MPTCP session between a first host and a second host, the first host is the host supporting MPTCP, and the second host is the host not supporting MPTCP, and when the MPTCP session is terminated, the processing module releases the corresponding IP address allocated to the MPTCP session. A transceiver module sets up the MPTCP session according to the IP address.

Abstract: Embodiments of the present application provide a service flow processing method, an apparatus, and a device. In the embodiments of the present application, SFs are classified, and a specific instance is not selected for a stateless SF, which can effectively reduce a quantity of SFPs and a quantity of SFP IDs used to uniquely identify the SFPs, reduce signaling overheads required by a controller to configure an SFP for an SFF, and reduce storage space of each SFF for storing configuration information.

Abstract: A rotatory device (1) for energy conversion between electrical energy and mechanical energy includes an end cap (20) to which electric conduction and commutation components (30) are attached. The end cap (20) is electrically insulating and has a flange mating to an electric conductive housing (10) of the rotatory device (1). An unpackaged capacitor (40) is positioned between the housing (10) and the flange (20) without occupying other space inside the housing (10) of rotatory device (1). The unpackaged capacitor (40) is electrically coupled to the electric conduction and commutation component and grounded to the housing (10) of the rotatory device (1).

Abstract: The present invention provides a method for updating a white space spectrum, an access device and a communication system, where the method performed by the access device includes: acquiring feature information of a white space spectrum, wherein the white space spectrum is currently used by the access device for communicating with a terminal, and the feature information comprises information about a bandwidth and a central frequency of the white space spectrum; sending an update request that comprises the feature information to a spectrum database device; and communicating with the terminal by using the white space spectrum identified by the feature information when a response for the update request from the spectrum database device indicates that the white space spectrum is available. The present invention optimizes a process of updating a white space spectrum.

Abstract: A method for mobility support selection includes determining a mobility class of a first application executing on a device, and determining if a subset of a plurality of available mobility support techniques associated with the entity one of meets and exceeds requirements of the mobility class of the first application. When the subset of the plurality of available mobility support techniques associated with the entity one of meets and exceeds the requirements of the mobility class of the first application, the method comprises selecting a mobility support technique from the subset of the plurality of available mobility support techniques, and sharing information related to the selected mobility support technique with other entities.
