Countryside Party Members And Cadres Of Modern Distance Education System Integrated Design And Implementation

Modern distance education system according to the network make possible with modern network technique of continuously maturity and progress. Modern distance education system is a kind of new education method that the calculator technique, multi-media technique, network and modern educate a technique to combine together. Countryside party members and cadres of modern distance education system can be free from the restriction in time, space and region factor, carry out excellent education resources share and raise a large countryside party members and cadres to synthesize character. The whole country have three kinds of modern distance education system currently according to satellite, cable TV and Internet. Countryside party members and cadres of modern distance education system of Jilin province physically sets out from what this saved in tallying up to succeed everywhere empirical foundation, decide to choose a telecommunication broadband network schema.Countryside party members and cadres of modern distance education system integrated design and implementation in conjunction with rural characteristics, from meeting party members and cadres in rural areas the application of modern distance education needs of departure, integrated design to build a broadband network based on the model of party members and cadres in rural areas of modern distance education system. Systematic use of provincial, municipal, and county levels platform to add TV set-top box as the main terminal device, via the Internet, including video to the site provides live, on-demand, graphics and other interactive digital media services.Countryside party members and cadres of modern distance education system integrated design to take full account of the system's utility and ease of use, the system's advanced nature and maturity, system security and reliability, system scalability and maintainability, the system's economy.In this paper, countryside party members and cadres of modern distance education system integrated design and implementation describes the overall network integration design ideas, integrated design into a new service-oriented architecture SOA design philosophy. System architecture using a distributed, modular design, from the information service of the long-term perspective, using provincial-level platform, municipal platform, county-level platform and receive the level of site design. Changes in customer demand growth scenario, the use of sophisticated architecture-based platforms and loose constantly to provide customers with new software services to meet customer needs. The system can be directly deployed on existing networks could be the development of the gradual expansion according to the user. System uses standardized integrated design, providing rich content interfaces. Information manages system of user-oriented and business services, according to different user types, in different regions of the content of configurations corresponding to accommodate the different needs of various applications.Integrated design systems set forth in the specific network of satellite receiving system hardware composition and functions; the hardware composition and functions of program format conversion system; the hardware composition and functions of multimedia asset management system; program distribution system of the national, provincial, municipal and system structure and function of four counties and districts; Program testing system hardware composition and functions; TV graphics site system hardware composition and functions; teaching information management system hardware composition and structure of the advantages; Assisted Instruction web site functionality and the corresponding system of web site support and service functions; information management system hardware composition and functions; broadcast management system hardware and core of the system as a whole realized functions; programming on-demand systems and video broadcast system, the platform formed a county-level functions; basic, extended and PC-based terminals to receive three types of site design and implementation of integrated programs.System network security design overview section describes the telecommunications system for broadcasting platform in the highest level of security, a dedicated data room, relying on the engine room a strong network security protection can be safe and effective broadcast. firewall as part of the a core of safety equipment, should have 15 pairs of performance, such as: Provide object access control of state inspection technology; Embedded VPN; Efficient transparent proxy implement application management control of fine grain; Support e-mail filtering and content security audit; Support for traffic management; Support priority level management of telecom broadband;Anti-TCP,UDP and other port scanning;Defense DoS / DDoS attacks ; Defense routing attacks, IP packet fragmentation attacks, DNS / RIP / ICMP attacks, SYN attacks and others ; Provide real time monitoring,audit and alarm function;Provide administrator certification of OTP system; Support flexible local and remote management; Provide detection of security policy; Provide a rich full log; Provide the log to download, backup and query function. Intrusion detection describes the definition of intrusion detection, network-based intrusion detection system, detectors and security control centers and functions, The six aspects of the network IDS specific functional requirements, such as: Intrusion detection of real time,distributed,cooperation in the network;Execute multiple levels of scanning according to managers need;Detection and scanning does not affect the normal network connection service and network efficiency;Detection library can be update in time;Safety testing policy can be set up by user. According to the different needs of users can select the appropriate detection policy; Virus protection policy set out in part of "layers of defenses, centralized control, to prevent the main, anti-killing combination"; security vulnerabilities countermeasures described in Part 5 of measures to reduce or eliminate security holes caused by the security system hidden; Security audit section describes the definition of security audits, security audits in the operating system, database, network-based, web sites and all kinds of applications, the scope of specific requirements.This application of relevant technologies in the system profile describes the system development environment. This software operating environment, opening up a more popular sites using current mode architecture (Linux + PHP + Apache + MySQL), that the use of Linux Redhat As4 U4 as the operating system, PHP4.3.9 as a server-side script interpreter, the origin and development of PHP language and the features of PHP language; Apache2.0.52 as a web server, the origin and development of Apache and the features of Apache; MySQL4.1.20 as a database, the origin and development of MySQL and the features of MySQL .As the four software is free or open source software, the use of this approach can establish a software development in which the economy and stable operating environment.Design and implementation of information management system to implement the user registration information section of the implementation method; In a group information management to achieve a new packet, modify the packet of information, delete the group, group property management, according to group user information query implementation method; Set forth in the contract management to achieve view contract information and further additional information see the contract implementation methods; Adding a new user in the achievement of specific implementations.Countryside party members and cadres of modern distance education system has been completed currently and has now become party members and cadres and the masses in rural areas to study the party's principles and policies, learning science and technology culture, and to understand all aspects of information, a rich cultural life of an important channel. Telecommunication broadband network schema of countryside party members and cadres of modern distance education system is a proven successful model, but also the most suitable for rural information technology, the most suitable model of the construction of new socialist countryside.
