Design And Implementation Of IPTV Terminal Management System Based On TR069 Protocol

With the promotion of triple play and the development of IP technology,the IPTV provides users with multiple integrated application services including radio,video and other services utilizing broadband IP network.Due to its full play the advantages of traditional TV and the Internet,it has become an important business of the next generation communication network and the inevitable choice for the development of digital TV industry.Recently the IPTV business is spreading in a large scale.Then more and more IP terminals are introduced into the network.The traditional SNMP protocol can't satisfy the needs of effective management for a lot of terminals.Therefore and how to achieve the effective management of a large number of terminals equipment has become a common concern in the IPTV business operations.The TR069 protocol is a network management protocol for terminal equipment.It is mainly used in the home gateway that provides a general framework of home terminal equipment configuration management in the next generation communication network.It can realize remote centralized management of home terminal equipment from the network side.TR069 protocol provides reference for solving the effective management of the IPTV terminal equipment.Based on the in-depth study of TR069 protocol,we design and implement the IPTV terminal management system based on TR069 protocol.The main research work is as follows:1.The functional requirements and performance requirements are proposed by analyzing the existing problems of terminal management system.And then adopt the TR069 protocol framework and LAMP technology to construct the architecture of TR069-based IPTV terminal network management system.2.Design and implement the common interfaces and function modules of terminal network management system.The interfaces include the SOAP message interface,the RPC method interface and the transaction control interface;the function modules include the authentication module,the parameter configuration module,the firmware version upgrade module and the fault diagnosis module.3.In the aspect of system security,in order to improve the security of the system we employ HTTP and SSL/TLS protocol combined with RSA encryption algorithm to realize the equipment identity and business function authentication4.The results of system operation and test show that the security,response speed,stability and concurrency control achieve the desired objectives and requirements,and it achieves a good scalability.In this paper,we design and implement the IPTV terminal network management system.Then we solve the effective management problems of massive terminal equipment in the WAN effectively.Moreover,it satisfies the data security requirements of information network transmission,and improves the stability and reliability of the system.
