Intelligent switching system of client access server and method for same

Abstract

An intelligent switching system of a client access server is characterized in deploying multimedia teaching systems and teaching clients in a local area network of each school, and deploying a backup server and a teaching client intelligent configuration system in a machine room of an internet data center. The multimedia teaching system of each school accesses the Internet through Internet IP of each school system. Local area network IP, Internet IP, and teaching resources of the multimedia teaching system are backed up to the backup server. The backup server reports received local area network IP of the multimedia teaching system, Internet IP, and teaching resources to the teaching client intelligent configuration system, and further reports IP of the backup server to the teaching client intelligent configuration system. The teaching clients of the teaching client intelligent configuration system binds teaching client intelligent configuration system IP addresses and domain name.

Description

technical field [0001] This method is based on the multimedia teaching technology of IP network, and is applied to the basic education industry. Background technique [0002] The user who uses the multimedia teaching system is a school teacher, and the user needs to be able to use the multimedia teaching system both at school and at home. Users access the multimedia teaching system through the local area network at school, and access the multimedia teaching system through broadband at home. [0003] Users use the teaching client to download or play multimedia teaching resources from the server of the multimedia teaching system through the IP network. The formats of multimedia teaching resources include video, audio, animation, documents, etc. In particular, the download of multimedia teaching resources in video format will occupy a relatively high network bandwidth. [0004] At present, the multimedia teaching system based on the IP network is deployed in the computer room...

AI Technical Summary

Problems solved by technology

[0005] The advantage of the multimedia teaching system deployed in the computer room of the Internet data center is that it can meet the needs of teachers at home through the broadband access of telecom operators, and can also meet the needs of teachers at school through access to the school LAN connected to the Internet; the disadvantage is that The time of classroom teaching is relatively concentrated, and there are many teachers who access the multimedia teaching system at the same time, especially when playing video resources at the same time, the bandwidth occupied is relatively high, which requires high Internet access bandwidth and access costs without affecting the use. Not only the school's LAN requires high Internet access bandwidth and access costs, but also the multimedia teaching system deployed in the computer room of the Internet data center also requires high bandwidth and cost

[0006] The advantage of the multimedia teaching system deployed in the school LAN is that the network bandwidth is high when used in the school, the response speed and service quality of multimedia resources are guaranteed through the network, and it is not affected by the Internet access bandwidth. The multimedia teaching system deployed in the school LAN uses Fixed IP access to the Internet, teachers can also access the multimedia teaching software system deployed in the school LAN at home; the disadvantage is: teachers use the LAN IP address to access at school, and use the Internet IP address to access at home, teachers need to memorize the LAN IP address and Internet IP address

[0010] Both methods can guarantee the stability, reliability and security performance of the system. Obviously, the second method is more economical, but requires the user to remember the IP of the backup server
