Abstract:

The IEEE 1588 precision time protocol PTP time-setting mode of operation can be used to dramatically improve the quality of time-based systems that rely on a physical layer syntonization source in addition to PTP. Based on the standardized PTP protocol and common network frequency distribution techniques, the PTP time-setting mode of operation is capable of distributing time over packet-based facilities with little or no impact by network packet delay variation PDV. In essence, the timing performance at a slave clock is directly related to the traceability, accuracy, and stability of physical layer packet-based systems e.g., Synchronous Ethernet or existing syntonization-based networks e.g., SONETSDH, DS1, or E1.
