传统的电信网络采用全球定位系统(Global Positioning System，GPS)接收机进行时间同步；一方面，随着电信网络业务的多样性发展及电信网络规模的不断扩大，对网络时间同步的实现成本及安全性提出了更高的要求；近年来，通过在网络内分发同步信息实现网络时间同步成为一种新兴的同步技术，如在以太网和分组传送网(Packet Transport Network，PTN)中采用1588精准时间同步技术实现网络时间同步。另一方面，随着网络容量的剧增，光传送网(Optical Transport Network，OTN)技术替代传统的同步数字系列(Synchronous Digital Hierarchy，SDH)技术、密集波分复用(Dense Wavelength Division Multiplexing，WDM)技术成为主要的骨干网传送技术；并且，随着三网融合及网络用户数量的激增，OTN设备也开始应用在城域网和接入网。The traditional telecommunication network uses the Global Positioning System (GPS) receiver for time synchronization. On the one hand, with the diversified development of telecommunication network services and the ever-expanding scale of telecommunication networks, the realization cost and security of network time synchronization Sexuality puts forward higher requirements; in recent years, network time synchronization has become an emerging synchronization technology by distributing synchronization information within the network, such as 1588 precision time in Ethernet and Packet Transport Network (PTN). Synchronization technology enables network time synchronization. On the other hand, with the rapid increase of network capacity, Optical Transport Network (OTN) technology replaces the traditional Synchronous Digital Hierarchy (SDH) technology and Dense Wavelength Division Multiplexing (WDM). Technology has become the main backbone transmission technology; and with the proliferation of triple play and the number of network users, OTN devices are also beginning to be applied to metropolitan area networks and access networks.

现有网络时间同步技术的商用多是在单一类型的网络内部实现通信设备之间的同步，同属于一个时间同步域；但是，随着网络的进一步融合，未来将存在通信网络上多个子网络属于独立的同步域的需求；而OTN作为主要的传送网，在多个不同的接入用户经由OTN承载传送时，如何分别独立的实现每个接入用户的时间同步，即如何承载不同用户网络的时间同步信息是亟需解决的问题。 The commercial use of existing network time synchronization technology is to realize the synchronization between communication devices within a single type of network, and belongs to a time synchronization domain; however, with the further integration of the network, there will be multiple sub-networks on the communication network in the future. The requirement of the independent synchronization domain; and the OTN as the primary transport network, how to independently synchronize the time synchronization of each access user when multiple different access users transmit via the OTN bearer, that is, how to carry different user networks. Time synchronization information is an urgent problem to be solved.
