MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202411103327 A) filed by Ciena Corporation on December 26, 2024, for Improving Holdover Of A Ptp Network In Btca Using Frequency Support.
Inventors include Arshad Saleem A; Ankur Saxena; and Sharad Srivastava.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: IMPROVING HOLDOVER OF A PTP NETWORK IN BTCA USING FREQUENCY SUPPORT Systems and methods for enhancing time holdover in a Precision Time Protocol (PTP) network involve leveraging the best available frequency support while disqualifying time input from a degraded PTP clock. A method (300) includes steps of entering holdover in Precision Time Protocol (PTP) indicating a degraded time synchronization state (302); determining parameters for a Best Time Clock Algorithm (BTCA), the parameters including a Frequency Traceable flag (304); providing the parameters to other nodes in the network (306); and implementing the BTCA including consideration of the Frequency Traceable flag, to select a Best Time Transmitter (BTT) while in the holdover (308).
