Which statement about IEEE 1588v2 PTP timing protocol is true?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
IEEE 1588v2 PTP (Precision Time Protocol) is a timing protocol that is designed to synchronize clocks between networked devices. It allows for the precise and accurate synchronization of clocks across a network, enabling applications such as real-time data transmission, multimedia streaming, and industrial automation.
Of the options given, only option B is true: IEEE 1588v2 PTP supports phase alignment and Time Of Date.
Option A is incorrect. IEEE 1588v2 PTP does not rely on stratum 1 traceable frequency synchronization to communicate with TDM (Time Division Multiplexing) network elements. Instead, it uses packet-based communication over IP networks to synchronize clocks.
Option C is also incorrect. While IEEE 1588v2 PTP does use multicast messaging, it also uses unicast and broadcast messaging as well.
Option D is also incorrect. While IEEE 1588v2 PTP is a highly accurate timing protocol, it is not specifically designed to function in the same way as SONET/SDH (Synchronous Optical Network/Synchronous Digital Hierarchy) networks. SONET/SDH networks are specifically designed for telecommunications applications and use a different timing synchronization protocol.
In summary, IEEE 1588v2 PTP is a timing protocol that synchronizes clocks between networked devices using packet-based communication over IP networks. It supports phase alignment and Time Of Date, uses multicast, unicast, and broadcast messaging, and is not specifically designed to function in the same way as SONET/SDH networks.
