1. The process by which the relative phases of precision clocks are compared for the purpose of defining a single time standard.
2. A process in which network synchronization is achieved by use, at all nodes, of oscillators that adjust their frequencies to the average frequency of the digital bit streams received from connected nodes.
Note: In frequency averaging, all oscillators are assigned equal weight in determining the ultimate network frequency.
