Abstract
A method and apparatus for controlling delay over a data path in a device for transporting Ethernet packets over an optical transport network. The device is configured to receive an incoming clock signal having a first frequency and an incoming data signal and to output an outgoing clock signal having a second frequency and an outgoing data signal. One or more delays over the data path in the device are measured in a predetermined measurement period. A phase adjustment amount is determined based on the one or more measured delays over the data path in the predetermined measurement period, and based on the determining phase adjustment amount, a phase of the outgoing clock signal is adjusted by a phase locked loop in such a way that the delay over the data path in the device is substantially equal to a fixed delay value.
