摘　　要：在数字通信网中,网络同步是一个非常重要的技术问题。在介绍网同步基本原理的基础上,分析了几种网同步方式的优缺点,指出了各种网同步方式适用的网络形式。根据某专用通信网网络特点和实际需求,设计了一种兼容准同步、外同步、主从同步和互同步方式的网同步软件方案,满足了专网的特殊需求。同时对方案中各软件模块的功能进行了描述及分析,并结合实际经验讨论了改善网同步稳定性的几个方面,具有工程实际参考价值。Synchronization is an important technology in the field of digital communication network. First,the basic principle of synchronization is introduced,then the advantages and disadvantages of several network synchronization modes are analyzed, and the network type each synchronization mode suited for is presented. Finally, according to the characteristics and practical requirements of the private network,a software solution that can provide plesiochronous synchronization,external synchronization, master-slave synchro- nization and mutual synchronization and meet the special requirements of the private network is given. The function of the software mod- ules is described and analyzed. Combined with the practical experience, several means to improve synchronization stability are dis- cussed, which provides references for practical engineering.
