IEEE 1588V2 STANDARD PDF

The Precision Time Protocol (PTP) specified in IEEE standard v2 is the latest in packet-based timing technology. Originally designed to provide precise. The IEEE v2 standard defines the Precision Time Protocol (PTP), which is used to synchronize clocks throughout a packet-switched network. May 13, How does IEEE v2 help manage time synchronization within Their accuracy varies according to manufacturing standards and even.

This synchronization is achieved through packets that are transmitted and received in a session between a master clock and a slave clock or remote clock client.

A boundary clock is both a clock source and a clock client. An ordinary clock is either a clock source or a clock client. However, a standzrd clock is always a clock source.

Precision Time Protocol

An ordinary clock on a device is always a clock client. Boundary clock—A boundary clock has multiple network connections and can act as a source master and a destination slave or clock client for synchronization messages.

It synchronizes itself to a best master clock through a slave port and supports synchronization of clients 15882v it on master ports. Boundary clocks can improve the accuracy of clock synchronization by reducing the number of v2-unaware hops between the master and the client.

Boundary clocks can also be deployed to 188v2 better scale because they reduce the number of sessions and the number of packets per second on the master. Ordinary clock—The PTP ordinary clock has a single network connection and can act as a source master or destination slave or clock client for synchronization messages. On devices, the ordinary clock is a slave, which receives synchronization reference messages from a master, either a grandmaster or a master boundary clock.

Precision Time Protocol – Wikipedia

You cannot configure an ordinary master on a device. However, a boundary clock can provide time to the ordinary slave.

The grandmaster clock is an external device to which the boundary or ordinary clock synchronizes. You cannot configure a grandmaster clock on a device. However, a boundary clock slave or an ordinary clock slave can receive time from a grandmaster clock.

Clock source—A clock source is the PTP master clock to which standar slave synchronizes. The clock source is included in the configuration of the slave clock.

The clock client is included in the configuration of the master clock. Unicast mode IPv4 on Gigabit Ethernet interfaces only —Unicast mode is a user-to-user protocol used to send a datagram to a single recipient.
