Systems and methods for the synchronization of a real-time scheduled packet network using relative timing |
摘要 |
A node of a real-time scheduled packet network synchronizes an internal frequency reference to a master node by receiving first heartbeat packets that are transmitted by the master node at a predetermined frequency. The node calculates a link phase of a link over which the first heartbeat packets are received by subtracting a time at which the node transmitted a second heartbeat packet to another node from a time at which the node received a first heartbeat packet.
