在电信级以太网中采用了IEEE1588协议作为实现网络时钟同步的一种技术。文章首先简单介绍了1588协议的架构,然后对协议实现时钟同步进行了算法分析,最后提出了一种利用FPGA技术实现协议的方法。
In the carrier-class Ethernet IEEE1588 protocol used as a network clock synchronization technology. The article first introduces the architecture of the 1588 protocol briefly, and then analyzes the algorithm to achieve the clock synchronization. Finally, a method of using FPGA technology to implement the protocol is proposed.
