Research And Design Of The Gateway Configuration Management Based On TR-069

With the development of computer network technology and applications continue to expand, home devices are gradually becoming information, networking and automation. Home network with a wide geographical distribution, type of device complexity, inconsistency of standards, taking up a lot of IP address resources, a wide range of business, and high security needs.To solve the current home network terminal equipment complexity and diversity of business raised management issues, DSL Forum in 2005 proposed to automatically configure manage these devices at the WAN management station. This is the WAN Management Protocol. The protocol is designed to use Hypertext Transfer Protocol (HTTP), and fully learn a lot of Web-proven technology, makes the protocol implementation is relatively simple and has good scalability. The protocol with C/S structure, the server side is responsible for maintenance and management of ISP, the client (agent) running on a customer premises equipment. The server calls the RPC method on the client through the Internet, It could zero-touch open basic telecommunications network business and its value-added services, rapid troubleshooting, improve user satisfaction.The paper takes home gateways for instance, based on the analysis of TR-069 protocol, in the home gateway to achieve automated configuration management system client. When we are designing the client, full account of the portability of the program, it can be easily ported to other customer premises equipment.Fisrt of all, the paper describes the basis of topics and the significance of the study, expound the concept of digital home gateway and the basic principle of TR-069 protocol, current situation both here and abroad and development trend. And clarify the paper's research objectives and the main content. Second, the paper has carried on the analysis of the protocol and gives direction for achieve the function and architecture. The paper provided a detailed analysis of the transaction session process between the Server and Client.Third, the paper from the application point of view, do a complete and detailed needs analysis. According to the needs, the paper designs the client program and protocol stack module architecture. Because of the huge amount of data processed by the system, so the paper also designs a system of congestion control scheme.Fourthly, according to the overall design, the paper abstracts each modules of the client software. For implementing the control flow of each module. Ultimately the paper to achieve the remote management capabilities, to complete the software system.Finally, the paper offeres the system deployable blueprint and test results. And point out the significance of the study and insufficient.
