摘要

摘要：SD-WAN 发展势头迅猛，电信运营商与互联网企业都在不断扩大布局。作为形态多样化的技术， SD-WAN 中并未对时钟同步做出明确规范。分析了时钟同步对 SD-WAN 技术实现和业务运行的重要性。简述了在SD-WAN被广泛采用的互联网公共NTP服务时钟同步方案的利弊，由此展开讨论在不同场景可实现的自建NTP服务时钟同步方案，并设计了基于自建NTP服务利用管理隧道加密传输NTP同步数据的时钟同步方法，使SD-WAN平台和设备在时间同步时获得更高的安全性与稳定性。

Abstract

SD-WAN is developing rapidly

and telecom operators and Internet companies are constantly expanding their layout.As a technology with diverse forms

SD-WAN has not made a clear specification for clock synchronization.The importance of clock synchronization to SD-WAN technology implementation and business running was analyzed.The advantages and disadvantages of the clock synchronization scheme of Internet public NTP service widely used in SD-WAN realizations were sketched.Thus the clock synchronization scheme of self-built NTP service in different scenarios was discussed.Furthermore

a clock synchronization method using management tunnel to transmit encrypted NTP synchronization data was designed

which made SD-WAN platform and devices obtain higher security and stability in time synchronization.
