Global clock consistency method for distributed computing systems
A patent application (Publication Number: US20240015234A1) describes a method for ensuring global clock consistency in a distributed computing system with multiple devices. The method involves receiving requests dependent on the order of two events processed on different servers, obtaining hybrid timestamps for each event, determining the event order based on these timestamps, and processing the request accordingly. The hybrid timestamp includes physical and logical components representing the time of the event and its sequence number, respectively. The system also measures and limits errors on the physical clock using a predefined model.
Furthermore, the patent application details a system and a computer-readable storage medium implementing the method described. The system includes a processor and memory storing instructions for receiving requests, obtaining hybrid timestamps, determining event order, and processing requests based on this order. The system also ensures that the hybrid timestamp remains constant in size over time and allows for error measurement and bounding on the physical clock. The computer-readable storage medium contains instructions for performing the method, including receiving requests, obtaining hybrid timestamps, determining event order, and processing requests accordingly. The timestamps used are two-tuples, implemented using a single numerical value, ensuring efficient and accurate global clock consistency in distributed computing systems.
