【摘要】：当今时代,通信行业巨大的流量为电信运营商带来了巨大的挑战,H公司为世界各地的运营商提供了由底层硬件设备到上层软件的完整的解决方案。OMC(操作维护中心)也就是这一电信解决方案的底层设备网络管理系统,网管系统可以给运营商的网络管理人员提供远程管理监控设备的服务,包括设备安装升级,配置管理,运行监控,故障分析,网管工具,系统设置等功能。笔者在项目中参与了项目的需求分析,设计和配置管理功能模块的开发工作。网络管理系统对系统的稳定性、安全性、可扩展性都有较高的要求,配置管理是网管系统的功能模块之一,也需要满足这些要求。鉴于此,该论文主要完成了以下工作：(1)调研了OSGi技术的优缺点,使用OSGi技术作为系统底层架构实现网络管理系统。该技术的使用满足了网管系统对模块化、动态性、可扩展性、稳定性、版本控制等特性的要求。(2)网管系统和配置管理功能模块的内外部接口的设计,配置管理功能的设计与实现。通过对配置管理功能模块的页面设计、功能设计、数据库设计等,实现了修改配置、保存配置、生效配置、核查配置等基本功能。(3)配置管理功能模块中子功能的实现,重点是密文功能和页面动态生成功能的设计与实现。其中页面动态生成采用了XML、J2EE、HTML等技术实现；密文功能采用AES-128和BASE64加密算法结合使用的方法实现了字符的加密工作。这两个子功能的实现使得系统的安全性、可扩展性有了进一步的提升。包含本项目中网管系统的电信解决方案已经在多个国家地区的电信运营商中上线使用,在使用的过程中系统的安全性与稳定性都得到了认可,达成了预期的目标。
[Abstract]:In today's era, the huge traffic in the communications industry has brought great challenges to telecom operators. Company H provides operators around the world with complete solutions from underlying hardware devices to upper software. OMC (Operations and maintenance Center) is the underlying equipment network management system for this telecommunications solution. The network management system can provide the network managers of operators with the service of remote management of monitoring equipment, including equipment installation and upgrading, configuration management, operation monitoring, fault analysis, network management tools, system settings, and so on. In the project, I participate in the project requirements analysis, design and configuration management function module development. Network management system has high requirements for the stability, security and scalability of the system. Configuration management is one of the functional modules of the network management system, which also needs to meet these requirements. In view of this, the main work of this paper is as follows: (1) the advantages and disadvantages of OSGi technology are investigated, and the network management system is implemented by using OSGi technology as the underlying architecture of the system. The use of this technology meets the requirements of the network management system for modularization, dynamics, scalability, stability, version control and other characteristics. (2) the design of the internal and external interfaces of the network management system and configuration management function module. Design and implementation of configuration management function. Through the page design, function design and database design of configuration management function module, the basic functions of modifying configuration, saving configuration, effective configuration, verification configuration and so on are realized. (3) the sub-function of configuration management function module is realized. The emphasis is on the design and implementation of ciphertext function and page dynamic generation function. The dynamic generation of the page is realized by XML,J2EE,HTML, and the encryption of characters is realized by the combination of AES-128 and BASE64 encryption algorithm. The implementation of these two sub-functions makes the security and expansibility of the system further improved. The telecommunication solution which includes the network management system in this project has been used online in the telecom operators in many countries and regions. The security and stability of the system have been recognized in the process of use, and the expected goal has been achieved.
