| With proliferation of Internet applications, networking becomes more and more popular. At the same time, through several years'development, the DSL (Digital Subscriber Line) technology is becoming maturely. TR069 is a management protocol at the WAN side proposed by DSL Forum in 2005, which defines the general framework that encompasses remote configuration and management of DSL CPE through network, which provides an auto-configuration capability with a standardized protocol. Coordinate with other skills realize remote auto-configuration with "zero on -side operation" is comparatively easy.This article mainly analyzes the protocol TR069, and then discusses how to realize remote terminal equipment in this protocol. A detailed description and design of protocol TR069 stack modules, TR069 realize various functions defined in protocol. This terminal management system, and the key technologies in the practical application of network configuration of "zero on -side operation" is the process and upgrade process validation CPE system function.Based on the following aspects innovation:1. Study on the basis of the protocol, and analyzed from the angle of communications request congestion control mechanism, restart notice mechanism, and in the thesis put forward the concept of tree parameters.2. The network environment, through the NAT modify the ACS configuration files and parameters of the network through NAT obstacle-free thought innovation, make the ACS can serve more changeable network environment.3. TR069 protocol defined the ACS is just a simple automatic configuration server, but the design of ACS in the business level, increase the extension work processing function, can be better with some CRM,BOSS system such as collaborative work.4. In practical applications, when the CPE IP addresses changes, the ACS cannot voluntarily. Increase in such cases reported the ACS configuration initiative CPE, preventing the function change when the CPE IP addresses changes not inquires problems. |
