    Abstract: In one embodiment, a packet switching device is configured to operate as a spoke or a hub in a Dynamic Multipoint Virtual Private Network (DMVPN) using one or more initially negotiated service overlay capabilities including service encapsulation to use in communicating service overlay data packets between the packet switching device and another device (e.g., spoke, hub) of the DMVPN over an established tunnel (e.g., secure protocol channel). The packet switching device is further configured to negotiate updated one or more service overlay capabilities including updated service encapsulation to use in communicating service overlay data packets with another device (e.g., spoke, hub) without dropping the already established tunnel. In one embodiment, the negotiation between the packet switching device and another device (e.g., spoke, hub) of the DMVPN uses Next Hop Resolution Protocol (NHRP). In one embodiment, the service encapsulation uses Network Service Header (NSH).

  • Patent number: 9456272
    Abstract: The disclosure provides a button-press detection and filtering method, related circuit, and button-press detection chip for a external device. A button-press signal from a wire control apparatus is coupled to the button-press detection chip for the external device. The button-press detection chip for the external device can digitally sample the button-press signal through the filter circuit and outputs a digital logic signal corresponding to a button to an audio codec according to the sampling result. The audio codec can determine a pressed button according to the digital logic signal and performs a corresponding function. With the solutions of the disclosure, a noise interference signal in a button-press signal may be avoided and a pressed button may be accurately detected, without using a dedicated chip or complex software codes in a wire control apparatus and an electronic device.
