The Network Exam System Design And Realization Based On The IPv6 And WEB Technology

Due to the rapid development of network, there is a new exam method gradually arises in the education field named network exam.This kind of exam can save resources,and also can facilitate the students'test,the teachers and personnel management. It get the world's attention to the examination reform education when the examination mode has rolled out.At the same time, combined with the high-tech method and the distance education of the student's is the important direction of the education.The network examination is the user take the examination through the computers which based on the LAN or the Internet. The students that take the exam can login the information to use the user name which have already registered and the password. The examination papers can generation according to the data the teacher has joined in. It can avoid the pre-exam situation. To improve the reading efficiency and reducing the teacher's pressure of sentenced the papers, the exam system can use the mode that the computers to sentenced the papers. The computers can statistic and rank the scores. So, it is the development trend of the network examination system research and development.But the current network examination system has backward, so the application is not widely, and this kind of new examination mode have not cognitive by the people,this kind of examination have not attracted the people's attention.The net have the limitation and the resources of IPv4 addresses have completely exhausted and the security of the net is not high and it is not sufficient for protect the system and so on, attribute to the great obstacles of the development of the network exam system. So the exam system based on the IPv6 is imperative.Through the requirements and analysis of the modern network exam system and the WEB technology based on the B/S mode,the JSP language,the database of SQL Server 2000 and the new concept of IPv6, the network exam system design by this article can save the cost and improve the efficiency of examination aspects.And combined with the IPv6 agreement and the network exam system can realize the network examination system with the advantages of IPv6.This system mainly faces three kinds of personnel:the administrators, the teachers and the students. They can realize their functions use different permissions.The network examination system advocates the learning and ways of examination of "flexible, gout, science, justice". It can play a role of learning and assessment for the students to master the knowledge.It also can make the teachers teach and examination the students at anytime and make the students learn the knowledge at anytime.This paper analyzes to the network examination system,due to the traditional IPv4 limited by the address,it is difficult to proceed remote security exam,because in remote exam,the IP address we used is doing the network address translation,not the real address,every student of the same topic can use the same IPv4 address,and when the IPv6 transmit the data,it can use the real address,realize the network examination system which use the IPv6 advantages.
