Abstract

A method and system for maintaining clock synchronization in a communication network having multiple clocks are disclosed. According to one aspect, the invention provides a first precision time protocol (PTP) instance and second PTP service instance. Dynamic PTP parameters and tuning PTP parameters are periodically cloned from the first PTP service instance to the second PTP service instance substantially in real time.
