【摘要】：由于广域网规模的不断发展,接入广域网中的设备日益增多,广域网上承载的业务也更加多样化,在广域网管理中采用集中-分布式管理结构已成为必然。广域网中接入设备的管理作为广域网管理的重要组成部分,变得越来越重要。同时宽带业务的发展,使得接入设备数量和设备类型增多,广域网中接入设备的管理也变得更加困难。当前大部分终端设备都提供了LAN侧的管理配置接口供管理人员进行上门维护,但这种维护方式效率低,成本高。因此如何对接入广域网中的大量终端设备进行更高效的配置管理成为了一个令人关注的问题。论文首先对广域网的网络管理模式进行了研究,知道广域网的网络管理系统不仅需要保证网络管理系统中数据传输的高效和可靠,同时要求完成对终端设备的管理和配置。为了满足这两个要求,对广域网管理中的关键技术,Web Service技术、数据传输技术和网络管理技术进行了研究,特别是对网络管理技术SNMP和TR-069的比较,最终选择了TR-069协议作为网管系统的核心协议。由于广域网中的终端设备大部分都是通过网关设备接入其中的,针对TR-069协议的特点,采用TR-069协议来对广域网的终端设备进行管理就必须进行网关的穿越。通过对TR-069协议中穿越网关机制,Device-Gateway Association机制和STUN机制的研究,发现了它们的局限性,在此基础上提出了在TR-069协议中采用ALG技术穿越网关的想法。论文的重点是提出了一种基于OpenWrt平台的TR-069网管模块设计方案,并对网管模块的实现进行了详细的阐述。最后,对模块实现的功能进行了测试,测试结果表明论文所设计实现的网管模块工作正常,实现了基本功能。
[Abstract]:Due to the continuous development of WAN scale, the equipment connected to WAN is increasing day by day, and the service carried on WAN is more diversified, so it is inevitable to adopt central-distributed management structure in WAN management.As an important part of WAN management, access equipment management has become more and more important.At the same time, with the development of broadband services, the number and types of access devices increase, and the management of access devices in WAN becomes more difficult.At present, most terminal devices provide LAN side management configuration interface for managers to carry out on-site maintenance, but this maintenance method is inefficient and high cost.Therefore, how to manage a large number of terminal devices in WAN more efficiently has become a problem of concern.Firstly, this paper studies the network management mode of WAN. It is known that WAN network management system not only needs to ensure the high efficiency and reliability of data transmission in the network management system, but also requires the management and configuration of terminal equipment.In order to meet these two requirements, the key technologies in WAN management, such as web Service technology, data transmission technology and network management technology, are studied, especially the comparison between SNMP and TR-069.Finally, TR-069 protocol is chosen as the core protocol of network management system.Because most of the terminal devices in WAN are connected through gateway devices, according to the characteristics of TR-069 protocol, it is necessary to use TR-069 protocol to manage the terminal equipment of WAN.In this paper, the limitations of TR-069 traversal gateway mechanism, Device-Gateway Association mechanism and STUN mechanism, are found, and the idea of using ALG technology to traverse gateway in TR-069 protocol is put forward.The emphasis of this paper is to put forward a design scheme of TR-069 network management module based on OpenWrt platform, and to elaborate the realization of network management module in detail.Finally, the function of the module is tested, and the test results show that the network management module designed and implemented in this paper works well and realizes the basic function.
