Abstract: Embodiments of this application provide a clock synchronization method and a related device. The method includes: determining delay information and a measurement clock offset of an nth link in N links between at least two to-be-synchronized hosts, determining a weight of the nth link based on the delay information of the nth link; and synchronizing clock time of the at least two to-be-synchronized hosts based on weights and measurement clock offsets of the N links. In the method, the clock time of the at least two to-be-synchronized hosts may be synchronized based on a weight and a measurement clock offset of each of the N links, so that errors are allocated to each link by using different weights. This improves precision of clock synchronization of a plurality of to-be-synchronized hosts, and reduces an error of the clock synchronization.
