Abstract
A distributed Precision Time Protocol (PTP) Transparent Clock (TC) provides a TC function based on overall residence time in a network at a server layer. That is, the server layer operates as a distributed TC for a corresponding client layer. A transport network includes a first node connected to a first client device; and a second node connected to a second client device over a server layer, wherein the first client device communicates to the second client device via a client layer, wherein the first node and the second node are synchronized to one another, and wherein the first node and the second node are configured to implement a distributed transparent clock on a PTP packet at the client layer, the distributed transparent clock includes a correction field in the PTP packet based on a residence time in the transport network at the server layer.
