Design And Implementation Of City Information Service System About Television Media

With triple play forward, radio and television operators are faced with a full range of increasingly fierce market competition, will face a number of types of business, increase, the market competition become more and more complex. Radio and television operators to overcome the original digital TV based services increasingly saturated pressure and to maintain growth, the only way is in the value-added business of a new round of competition.Design and research of city and television media information service system is an important content of radio and television of tri networks integration project. The system is composed of two parts of hardware and software. The main content includes hardware and network architecture design and implementation, system software research and design, system performance test and analysis etc.Research on the system of hardware and network with redundancy heat backup is designed, in which, the firewall using HA mode, using HSRP mode switch, load balancing using VRRP mode, the server uses the Bonding mode. Multiple PORTAL servers through load balancing after the use of unified virtual address external services.The system software mainly includes content access system, audit release system, navigation and monitoring system of portal system. Content access system is mainly used Serv-U software to carry on the design; audit released system is mainly the use of JAVA code, running in the TOMCAT environment, for security checks, to receive the content text filtering, normative inspection and in through the audit content is released; portal navigation system is the use of JAVA code, running in the TOMCAT environment, the main navigation page for editing and presenting the set-top terminal; monitoring system is mainly use the script file and HostMonitor software business and network of the system monitoring.System testing using LoadRunner software. The results of performance test, all the technical indicators have reached or exceeded the requirements of acceptance outline. By the project test, stable and reliable operation of the system.
