SNMP代理在TD-SCDMA接入网中的应用研究与实现
摘要
随着计算机网络的不断发展,规模的不断扩大,以及网络中被管设备的不断增加,对计算机网络的管理就显得尤为重要。代理作为网络管理的重要组成部分,在网络管理中起着无法替代的作用。我国在第三代移动通信系统领域的深入研究,给代理的研究与开发带来了新的挑战。如何实现第三代移动通信系统接入网设备的代理成为我国通信领域的重要工作之一。本课题通过研究SNMP(Simple Network Management Protocol)代理及NET-SNMP体系结构,并将其应用于TD-SCDMA(Time Division Synchronous CDMA)接入网系统中,完成无线接入网代理的设计与实现。
本文从应用角度研究了SNMP代理的工作原理、管理信息库的存储结构及NET-SNMP的扩展方法和体系结构,并介绍了课题的应用平台。通过分析当前接入网代理的不足,利用主代理与子代理相结合,代理式与嵌入式相结合的思想,解决了接入网代理的性能问题,实现了性能采集的全采全报。本文从功能需求出发,依据软件工程的理论,设计无线接入网主代理为主代理核心模块、配置管理模块、性能管理模块、数据管理模块、日志维护模块和主代理接口模块;子代理为子代理核心模块和应用任务模块。以多线程、双缓冲区和多数据存储文件机制实现各模块的并行工作,提高工作效率。论文还详细阐述了各线程间的通信方式,消息、配置数据和性能数据的格式及各线程的工作流程。最后给出了系统测试与应用效果,以验证和检测系统的可用性。
本系统在中国普天信息技术研究院有限公司开发完成,经过多次测试运行良好,并应用于北京、天津和秦皇岛的第三代移动通信试验网络中。
As the continuous development of computer networks, network scale had expanded a lot. More and more network equipments needed management. So it is particularly important to manage the computer network. As a part of the network management, agent had played an indispensable role. As our country’s in-depth study in the field of the 3rd Generation Mobile Communication System, it had brought a new challenge for the research and development of the agent. How to achieve the equipments’agent of the access network in the 3rd Generation Mobile Communication System had became one of the most important jobs. By the research of the SNMP(Simple Network Management Protocol) Agent and the NET-SNMP’s architecture, this issue designed and implemented the agent of the RNC(Radio Network Controller) in TD-SCDMA(Time Division Synchronous CDMA) UTRAN.
This paper researched the principle of the SNMP agent, the storage structure of MIB(Management Information Base), the expansion method and the architecture of the NET-SNMP, and also introduced the application platform of the subject. To resolve the performance problem of current agent, this paper used a mothod of master-agent and sub-agent achieved all-collect and all-report. The arctical divided master-agent into the core module of the main-agent, the configuration management module, the performance management module, the data management module, the log maintains module and the interface module of the master-agent and divided sub-gaent into the core module of the sub-agent and the application tasks module according to the function requirements of the RNC. The issue implemented each module by using the multithreading, multiple buffer pool and the data storage mechanism of multiple files, so that it could achieve the purpose of parallel work of each module and improv the work efficiency. The paper also elaborated on the various means of communication between the threads, the format of the message, the configuration data and performance data, and the workflow of each thread. Finally, the paper showed the results of system testing and application, so that we could verify and detect the availability of the system.
The system was developed in the POTEVIO. This system was well worked after several tests, and was used in the experimental network of the 3rd Generation Mobile Communication in Beijing, Tianjin and Qinhuangdao.
