Police Academies Network Teaching System And Research

In the era of knowledge based economy and information technology, computer and network technology developed very fast. In recent years, education network system technology in particular has developed rapidly; making network-based multimedia applications in research and development all have made considerable progress, which brought far-reaching impacts to the higher education system. Among which, police academy online teaching system is one of a typical example of such systems. Network multimedia education system involves extensive content. It has complex technology, large systems and it put forward many new topics for the R & D for such system. Especially, how to better store, publish and manage multimedia information based course on to network is one of the key point and priorities.This paper focuses on how to implement server clusters service and network security monitoring system. Mainly three aspects including the teaching system architecture design, server deployment, and security monitoring on the performance of the server.Firstly, it provide the experimental study of the overall system design, describes the system of all the major functional components, and server deployment design. And then from the functional point of view discussed sever cluster system application server, database server clustering system and the detailed steps of network monitoring. For the network teaching system for police institutions, this paper presents a firstly design the system performance framework with a pursuit of the overall system reliability. Set up abstract model and the establishment of the system proposed by level of performance reliability in accordance with the requirements, application server load balancing cluster. With respect to publish large amount of multimedia data on web, through comparative study, we adopted using the MySQL database cluster architecture, and the use of Linux systems based on the design of the overall server deployment program.This paper studied the use nagios for the Linux network performance and security monitoring, the network client end and server-side monitor at the same time. In the end, it provide public security institutions with overall development of network teaching system summary and analysis framework for future development and prospects.
