Patent number: 9544018Abstract: In a multiple interface, low power and lossy network comprising multiple nodes, a root phase device obtains phase differential and absolute phase information from the devices in various network paths. Each device in a network path determines the differential phase data compared to its parent device in a network path. The device transmits the differential phase data to the parent device. The parent device transmits the differential phase data up the network path toward the root phase device. The root phase device collects the differential phase data and transmits the data to a central device. The central device determines the absolute phase of all devices. The root phase device can propagate absolute phase information to all devices within the network. Each device determines the absolute phase data by comparing the phase data of the device with the absolute phase data. The phase data is transmitted to a central device.Type: GrantFiled: January 13, 2014Date of Patent: January 10, 2017Assignee: CISCO TECHNOLOGY, INC.Inventors: Jonathan W. Hui, Wei Hong

Patent number: 9537590Abstract: Apparatus and methods relating to synchronization of communication equipment are disclosed. Synchronization information received from a bonded communication link can be used to synchronize local and/or remote communication equipment, such as femtocell sites coupled to nodes in a ring network. This may involve isolating a frequency reference signal from a DSL (Digital Subscriber Line) communication link which is a constituent link of a bonded communication link, for example. In a ring network, received synchronization information could be used in synchronizing a locally connected installation of communication equipment, and passed for transmission in the ring network for synchronizing other communication equipment. Such dropping and passing of an analog frequency reference signal could be applied in networks having other topologies as well. At least some embodiments of the invention are applicable to optical links.Type: GrantFiled: December 18, 2013Date of Patent: January 3, 2017Assignee: GENESIS TECHNICAL SYSTEMS CORP.Inventors: Stephen P.
