Robust distribution of ip timing signals

A method, comprising:

• receiving, at a 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 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.

A method, comprising:

• receiving, at a plurality of PTP-enabled network devices comprising switches, an announcement from a master clock device, wherein the announcement is received via a transparent clock switch coupled to the plurality of PTP-enabled network devices;
• synchronizing 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 comprising switches.
