Patent number: 9473372Abstract: In general, techniques are described for delegating responsibility for performing a connectivity protocol from one or more endpoint devices to network infrastructure situated along a network forwarding path connecting the endpoint devices. In some examples, an intermediate network device includes a connectivity protocol module of control unit that operates a connectivity protocol session on behalf of a server, wherein the server exchanges application data with the client using an application-layer communication session with the client. The connectivity protocol module monitors connectivity for the application-layer communication session with the connectivity protocol session by exchanging connectivity protocol messages for the connectivity protocol session with the client to determine a connectivity status for the communication session.Type: GrantFiled: November 9, 2015Date of Patent: October 18, 2016Assignee: Juniper Networks, Inc.Inventors: Gert Grammel, Chien Yu Li, Theodore X.

Patent number: 9166848Abstract: A frequency-shift keying (FSK) receiver includes an injection-locking oscillating circuit to receive a FSK input signal, and a phase detecting circuit. The injection-locking oscillating circuit outputs a locked signal having a phase that tracks a phase of the FSK input signal. A difference between the phases of the FSK input signal and the locked signal is associated with a difference between a frequency of the FSK input signal and a free-running frequency of the injection-locking oscillating circuit. The phase detecting circuit receives the FSK input signal and the locked signal, and outputs a baseband logic signal according to the difference between the phases of the FSK input signal and the locked signal.Type: GrantFiled: May 20, 2014Date of Patent: October 20, 2015Assignee: NATIONAL CHI NAN UNIVERSITYInventors: Yo-Sheng Lin, Chien-Chin Wang, Chien-Yu Li
