=== Precision Time Protocol

Precision Time Protocol (PTP) is a network protocol developed by the IEEE to enable sub-microsecond time synchronization in a computer network. Since its inception and for a couple of decades now, PTP has been in use in many industries, but it has recently seen a growing adoption in the telecomunication networks as a vital element to 5G networks. While being a relatively simple protocol, its configuration can change significantly depending on the application. For this reason multiple profiles have been defined and standardized.

While being a relatively simple protocol, its configuration can change significantly depending on the application. For this reason, multiple profiles have been defined and standardized.

In this section only telco specific profiles will be covered and, as a consequence, timestamping capability and a PTP hardware clock (PHC) in the NIC will be assumed. Nowadays all telco grade network adapters come with PTP support in hardware, but you can verify such capabilities with the following command:
