A METHOD FOR ESTABLISHING CLOCK TRACE RELATIONSHIP AND AN EQUIPMENT FOR COMPUTING CLOCK TRACE RELATIONSHIP

摘要

A method for establishing clock trace relationship and an equipment for computing clock trace relationship are disclosed. The method includes the steps as follows: computing a shortest path tree (SPT) from a clock source access node in the network to a set of other nodes; selecting nodes supervised by the clock source access node according to the SPT and the clock source information corresponding to the SPT; establishing the clock trace relationship one by one from the clock source access node to the supervised nodes along the SPT. The equipment for computing clock trace relationship includes: path computing unit, source selecting unit and path issuing unit.
