1. A method for synchronizing boundary clocks in a plurality of PTP-enabled network devices, comprising:
receiving, at the plurality of PTP-enabled network devices, an announcement from a master clock device, wherein the announcement is received via a transparent clock switch, wherein the master clock device and the transparent clock switch form an out-of-band PTP distribution network;
synchronizing the boundary clocks to a master clock generated by the master clock device based on a timestamp of the master clock and a transit delay corresponding to the transparent clock switch;
transmitting timestamps of the boundary clocks to media nodes connected to the plurality of PTP-enabled network devices; and
transmitting non-PTP data signals from the plurality of PTP-enabled network devices to a plurality of non-PTP enabled network devices.
