  • PTP over IP in a network topology with clock redundancy for better PTP accuracy and stability
    Patent number: 9819541
    Abstract: In one embodiment, a technique for implementing precision time protocol (PTP) over a packet transport (e.g., IPv4, IPv6, etc.) with clock redundancy is provided. The technique may involve maintaining clock synchronization by a PTP node, where the PTP node participates in an exchange of one or more messages with a current master node and at least one connected node that is a slave to the PTP node. The technique may also involve detecting one or more conditions that prompt a switch to a new master PTP node. The technique may further involve selecting the new master PTP node, and determining, based on the selection, whether the new master PTP node is a slave to the PTP node. The technique may yet further involve taking action, based on the determination, to indicate to the new master PTP node that the PTP node is not a suitable master.
