The construction of campus network mainly includes three aspects, namely, the construction of campus network facilities, the physical construction of campus network and the construction of campus network software environment. campus Website construction The above requirements must be met. In order to achieve various requirements, it is necessary to have corresponding software and hardware support. The campus network facilities include the following parts.
(1) Network equipment
Campus network equipment includes generic cabling, servers, switching equipment (switches, hubs, routers, etc.) and user terminals. ① Generic cabling. The physical layer of the campus network should be designed according to the relevant specifications and standards of the "Generic Cabling System Engineering". The backbone line should use optical fiber, and the backbone network should not be lower than the level of "IOOM Fast Ethernet". ② Server. Hardware: It should be equipped with a safe, stable and reliable dedicated service machine. Capacity and 1/0 throughput should be determined according to needs. Software: The whole system shall be configured with software with the following functions at least, such as database server, Web server, Video server, E-mail server, network management server, etc. Operating system: Windows NT, UNIX and other network operating systems are recommended. ③ Switching equipment. The selection of switching facilities should consider building block design to meet the needs of network expansion. ② The server. Hardware: It shall be equipped with a safe, stable and reliable dedicated server. Capacity and I/O throughput shall be determined as required. Software: The whole system shall be configured with software with the following functions at least, such as database server, Web server, Video server, E-mail server, network management server, etc. Operating system: Windows NT, UNIX and other network operating systems are recommended. ③ Switching equipment. The selection of switching equipment shall consider building block design to meet the needs of network expansion. ④ User terminal. PC is preferred. The main frequency should be higher than 133M. The operating system should be Windows95 or higher. The 1OM/100M white adaptive network card can also be used. Other special communication line exits can also be used as required.
(2) Agreement
The campus network in each area shall adopt the same protocol to facilitate data exchange. TCP/IP protocol shall be preferred for network layer/special layer protocol.
(3) Storage of resources
A large number of teaching software and multimedia information are often run in the campus network. The hardware and software requirements for storage resources are as follows: the hardware should use a large capacity hard disk, disk array or optical disk library, and a large capacity tape drive; The video information storage format shall be MPEG (MPEG1, MPEG2).
(4) Resource acquisition
Campus network resources can be obtained from the following three ways according to the needs of the school, namely, online, outsourcing media and self production. The self-made part shall be equipped with the following equipment: ① information source acquisition equipment; ② Program production equipment (including linear equipment and nonlinear equipment); ③ Disc burning device.
(5) Campus network management
"Continuous availability" is the first life of the network, so the purpose of campus network management is to ensure the normal operation and sustainable development of the campus network after its initial completion. ① Network management organization. There should be a fixed network management organization and personnel to ensure the normal operation of the campus network. ② Resource base and secondary application development. There should be a fixed organization and personnel to carry out secondary development of the application software and constantly improve the teaching resource database with the characteristics of the school. ③ Training. Campus network is a new technology, which has a process of updating and adapting the knowledge of teachers and students. Therefore, while building campus network, technical training should be carried out, especially the training of teachers should be guaranteed in terms of time and funds. ④ Financial guarantee. In the school's annual or monthly financial plan, there should be funds to ensure the normal operation and development of the network. ⑤ Regulations on Administration of Campus Network Use. Formulate the "Campus Network Use Management Regulations" suitable for the school to ensure the most effective use of the network. ⑥ Regulations on the Administration of Campus Network Security. Formulate the Campus Network Security Management Regulations suitable for our school.
