IEEE1588V2路径延迟自动测量和非对称性补偿

Path delay auto measure for asymmetry compensating in IEEE1588V2

介绍了基于IEEEl588V2的精确时钟同步协议(PTP)系统中为提高普通主时钟与普通从时钟之间时间的同步精度。与此同时,简化设计了一种自动补偿方法,该方法对电路路径延迟的自动测量以及对电路路径延迟造成的不对称性进行硬件上的自动补偿。

The paper introduces one way ofimproving the synchronizing precision and simplifying the way of improving synchronizing precision between ordinary clocks （OC） master and ordinary clocks slave in PTP system based on the IEEE1588V2 protocol. The way is the circuit path delay auto measure and auto compensate for asymmetry in the IEEE 1588V2 system by hardware.
