Systems and methods for clock synchronization are disclosed in which a primary node generates special physical laver clock sync symbols from the output of a reference clock and inserts the clock sync symbols within a symbol stream to one or more secondary nodes. Upon receiving a symbol stream, a secondary node can extract the clock sync symbols from the stream to synchronize its local clock with the reference clock of the primary node. In particular, the clock sync symbols can be inserted into the symbol stream at any arbitrary symbol location, e.g., even between consecutive symbols of a symbol encoded data frame. The clock sync symbols can also replace some control symbols in the symbol stream, such as idle or comma symbols. Accordingly, the clock sync symbols can be inserted into a symbol stream at fixed intervals, irregular intervals, or at any arbitrary time for high resolution clock synchronization.

This application provides a cluster resource scheduling method, system, device, and storage medium. The method includes acquiring task queues of multiple node resources. Each task queue includes multiple scheduled tasks and corresponding scheduled time periods. The queue intervals of the multiple scheduled tasks are determined according to the scheduled time periods. The queue intervals include fixed intervals and variable intervals. If the scheduled tasks are in a fixed interval, the scheduled tasks in the fixed interval of each task queue are executed based on a pre-set fixed interval scheduling strategy. If the scheduled tasks are in a variable interval, the scheduled tasks in the variable interval of each task queue are executed based on a pre-set variable interval scheduling strategy. This method solves the technical problem of unreasonable allocation of test resources.
