Software and Hardware Design of Extraction and Insertion System of SDH Network Management Information

摘要:

现有的不同厂家的同步数字体系(synchronous digital hierarchy,SDH)设备网管信息不能实现互通,为了解决这一问题,提出了一种SDH网管信息提取和插入系统的软硬件设计方案,主要包括网管信息的提取和插入、HDLC数据的封装和拆封、利用主控制器和USB模块进行数据传输,从而实现网管信息的高速上传并在上位机实时显示和保存功能；最后对该系统进行了测试验证,结果表明该系统能分析不同的SDH设备网管信息,为网管信息互通提供了基础信息。

Abstract:

In order to solve the different optical network transmission equipment cannot achieve network communication problems,the method of software and hardware design of Synchronous Digital Hierarchy management information extraction and insertion system is proposed. Mainly including the extraction and insertion of network management information, packing and unpacking of HDLC data and using the master controller and the USB module for network management information transmission to achieve high speed upload and real-time display and save in the host computer. Finally the system is tested to verify, the results show that the system can analyze different Optical Network equipment network management information and provides the basis for network management information exchange.
