VERFAHREN UND VORRICHTUNG ZUR RÜCKVERFOLGUNG EINER TAKTQUELLE

摘要

A method and an apparatus for tracking a clock source are disclosed herein. The method includes: determining a best clock source that needs to be tracked by a device according to a best clock source tracked by a slave candidate port in the device; and distributing the best clock source tracked by the device through a master candidate port in a master state. Through the embodiments of the present invention, the clock source selection of the device converges quickly. Moreover, because the slave candidate port is determined according to the network planning, the planning of the transport network is observed.
