Best Master Clock Algorithm

The Best Master Clock Algorithm (BMCA) is an algorithm for selecting the best grandmaster in a PTP network. It evaluates various time sources based on their quality and selects the most suitable one as the grandmaster. This algorithm ensures that only one grandmaster is active in a network and all other devices synchronize with it. The implementation of BMCA is crucial for the redundancy and reliability of PTP networks.
