Introduction - If you have any usage issues, please Google them yourself
The paper introduces the concept of IEEE 1588 synchronization mechanisms and explains then in more detail how PTP was enhanced, e.g. by Transparent Clock (TC), peer-to-peer delay measurement, unicast operation, pure layer 2 operation,enhanced accuracy, and extension mechanisms. Application examples show how these
enablers are used by industry. Compatibility between PTP version 1 and version 2 is discussed.
