【摘要】 随着网络技术的发展,音频传输逐渐网络化,为保证音频数据传输的实时性,对异步的以太网提出了高精度的时间同步要求。而IEEE1588标准定义的PTP(Precision Time Protocol)协议正是为实现高精度时钟同步而制定的。本文系统地介绍了IEEE1588v2(第二版本的PTP协议)的原理,并从软件实现的角度给出了IEEE1588v2的总体设计。更多还原

【Abstract】 With the development of network technology,the gradually networked audio transmission set higher demands on asynchronous ethernet to provied high precision time to guaranty the real-time of transmission of audio data.Fortunately,IEEE1588 is precisely designed to solve this problem.This article systematically describes the principle of IEEE1588(version 2),and presents the general design of IEEE1588v2 in the angle of software implementation.更多还原
