IEEE 1588v2 PTP is a packet-based two-way message ex change protocol for sync hronizing a local clock with a primary reference clock or a grand master clock in hierarchical master-slave architecture. This synchronization is achieved through packets that are transmitted and received in a session between a master clock and a slave clock.
What is IEEE 1588v2 Precision Time Protocol?
IEEE 1588v2 Precision Time Protocol (PTP) is a packet-based tw o-way message exchange protocol for synchronizing clocks between nodes in a network, thereby enabling an accurate time distribution over a network.This document explains how to configure IEEE 1588v2 PTP on the Cisco ASR 1002-X Routers.
What is the transmission delay for 1588v2?
The transmission delays are symmetrical between master and slave (i.e. time to travel from master to slave is the same as from slave to master) When carried over a Carrier Ethernet Network (CEN), 1588v2 requires a dedicated CoS or even a dedicated EVC – with stringent requirements on Frame Loss Ratio, Frame Delay and Inter-frame Delay Variation.
What is iaieee 1588v2?
IEEE 1588v2 is a standard that defines a Precision Time Protocol (PTP) used in packet networking to precisely synchronize the real Time-of-Day (ToD) clocks and frequency sources in a distributed system to a master ToD clock, which is synchronized to a global clock source.
