Patent number: 11683111Abstract: A method and system for the post-adjustment (i.e., offline) of event timestamps to implement virtual time synchronization amongst detection node clocks. In existing methodologies with the goal of clock synchronization, clocks (and timestamps generated therefrom) are disciplined or adjusted at the recordation time of the events on a detection node (e.g., a switch/router, an Internet-of-Things (IoT) device, a wireless sensor, etc.). However, there is no particular reason for these clocks or timestamps to be accurate during the recordation time, but rather, should be accurate at their use or interpretation time. Further, through these recordation time adjustments, clock drifts and timing errors may be gradually introduced, leading to runaway inaccuracies. The disclosed method and system intentionally avoids the disciplining of clocks at event recordation times on the detection node and, instead, adjusts timestamps during interpretation times, to overcome the aforementioned issues.Type: GrantFiled: March 24, 2021Date of Patent: June 20, 2023Assignee: Arista Networks, Inc.Inventors: David C. A. Snowdon, David J. Mirabito

Patent number: 11671194Abstract: Technologies for high-precision timestamping of data packets is disclosed. Several sources of errors that may arise when timestamping the arrival or sending of data packets may be determined and corrected, including variable latencies, semi-static latencies, and fixed latencies. In the illustrative embodiment, a variable latency may arise due to a phase difference between a clock of a network interface card and a system clock. When a trigger pattern is detected, such as the start of a data packet, a trigger may be sent from a circuit synchronized to the clock of the network interface card to a circuit synchronized to the system clock. The phase difference between the edge of the clock on the network interface card and the edge of the clock of the system clock leads to an error in the timestamp value. Determining the phase difference allows for the error in the timestamp value to be corrected.Type: GrantFiled: November 16, 2021Date of Patent: June 6, 2023Assignee: Intel CorporationInventors: Mark A. Bordogna, Janardhan H. Satyanarayana, Larry N. Wakeman, Robert G. Southworth, Mika Nystroem
