Abstract: A system for maintaining a Precision Time Protocol (PTP) hardware clock, the system being operative in conjunction with a network device which is external to the system, the system comprising a controller to receive information characterizing a network peer oscillator frequency, wherein the information was extracted from an RX symbol rate, and to adjust the PTP Hardware Clock's frequency responsive to the information characterizing the network peer oscillator frequency.

IPC: H04L7/00
Abstract: A network device includes control logic coupled to a receiver. The control logic detects an synchronization packet received via the receiver from a second network device over a network that is precision time protocol unaware. The control logic determines that a portion of the synchronization packet is asserted, indicating that the synchronization packet has incurred congestion traversing the network. The control logic adjusts, based on an assertion of the portion, a weight applied to timestamps associated with sending and receiving the synchronization packet in performing clock synchronization with the second network device.

Abstract: System, methods, and devices for sharing time information between machines are provided. In one example, a system includes a Precision Time Protocol (PTP) Hardware Clock (PHC) and an application. The application receives time information from the PHC along with contextual metadata associated with the time information, analyzes the contextual metadata associated with the time information, and determines a context in which the PHC is disciplined. The context in which the PHC is disciplined may control a manner in which the application uses the time information.
