N2 - IEEE 1588 is a standard used in the synchronization of independent clocks that run on separate nodes of a distributed measurement and control system. This work presents a method that employs dual slave clocks in a slave to measure the link propagation delay, clock skew and offset. By accurately deriving these parameters, the proposed approach can reduce the deviation from the master clock to several orders of magnitude better than the required specification. The proposed technique fully conforms to the IEEE 1588, and can be used in the environments of symmetric and asymmetric communication links, such as xDSL.
