It is necessary to clarify a series of questions such as "what is a campus network", "what functions a campus network should have" and "what is the goal of building a network". Don't take one step at a time, have a clear plan, direction and goal, and don't follow suit.
Second, the campus network scheme of some schools is unreasonable, wasting funds and failing to reach the goal. Newly-built schools, campus network construction has financial guarantee, and the conditions are good. However, the problems in the design scheme are more prominent and the configuration is not very reasonable. For example, in the campus network scheme of a primary school, the scale of the campus network is not large, the core switch adopts a higher-level three-layer switch (the three-layer switch can be routed across network segments), and the access switch adopts the lowest-end non-network management switch, which is equivalent to wasting the money of a three-layer switch. Due to the idea of "one step in place", some schools have high campus network configuration and huge investment, and the technology of information technology teachers has not kept up, and the functions of equipment have not been fully exerted, resulting in serious waste.
The Education Bureau should establish a corresponding scheme design team and strengthen the guidance on the construction of campus network in primary and secondary schools. The Education Bureau can organize excellent high school information technology teachers (generally information technology majors) and modern educational technology teachers to set up a campus network construction scheme design team. To build or upgrade the campus network in primary and secondary schools, the design team should analyze the needs and design suggestions of the school, make the design scheme as reasonable and effective as possible, and improve the cost performance of the campus network construction.
Second, the construction of campus network, like the construction of any network application system such as enterprise network, should follow the theory of 1: 1: 1, so as to make the construction of campus network reasonable and maximize the benefits of campus network.
What is 1: 1: 1 theory? That is, in the construction of network application system, the proportion of hardware construction cost, software construction cost and management, maintenance and training cost is roughly 1: 1: 1. If this theory is violated, it is difficult to ensure that the benefits of the network application system can be brought into full play. This theory is also applicable to the construction of campus network, but many schools have not done this in the construction of campus network, which is manifested in the following aspects:
1, attach importance to network hardware construction and despise software construction.
Campus network software construction can't keep up, and the application is single. Many schools only use computers to connect to the Internet through the Education Metropolitan Area Network (MAN) to form a local area network (LAN), and the internal applications are only resource sharing and printer sharing. Many schools are unwilling to spend money on software, or even to buy anti-virus software and use pirated software. Once the virus breaks out, the whole network collapses; There is basically no school management software, and many schools don't use the campus network management platform issued by the Education Bureau.
Principals of primary and secondary schools should improve their information literacy, attach importance to the construction of campus network software and give full play to the role of campus network. Software construction should be gradual, and we can't go all out. The application systems should be put into operation one by one, and each application system should be put into trial operation before, so as to ensure that each application system can play its benefits, strive for a return on every investment, and avoid investment waste. Software should adopt a mature platform, and choose software that is easy to maintain, upgrade and expand. And considering the future upgrade costs, signed an agreement to prevent worries.
2. The management and maintenance of the campus network can't keep up, and they are unwilling to spend money on training.
Campus network administrators in rural schools are basically not information technology majors, nor are they full-time campus network administrators. Their main task is the teaching of information technology courses. Many schools don't even count the workload of campus network administrators. As a free lunch, they are unwilling to spend money on the training of campus network administrators. How can such a campus network ensure normal operation and how can such a network manager keep up with the rapid development of information technology (especially network technology)?
Network management is unstable, once this information technology teacher is in charge, once it teacher is in charge; Taking training as a kind of treatment, several teachers take turns to participate in a systematic training. How can such training achieve the training goal?
The Education Bureau should strengthen the training of network administrators in primary and secondary schools, and the training forms can be diversified, such as special lectures, systematic professional training, and the combination of teaching, research and training.
Three, the campus network construction should have a strategic vision, moderately ahead, and develop steadily.
The construction scheme of campus network should be economical and practical, appropriate and ahead of schedule. Affordability does not mean low grade and weak function; Money should be spent on the cutting edge, and the place where it should be invested should be willing to invest. Don't turn the campus network into an image project, which is flashy and useless. Network products are developing rapidly, and the prices are also decreasing rapidly. If your network equipment is very advanced, but the advanced functions are often not used for the time being, when these functions are used, the price of these equipment has dropped several times, and your investment is seriously wasted. Is it enough to advance? Let's just say it still works today. That's not true. First of all, we should consider that it is enough now and will not be eliminated in three or four years, and then consider the compatibility and expansibility of the equipment, so as to prepare for the future upgrade and update, and extend the elimination cycle of the equipment as much as possible.
Keep the network management stable and connect alternately. Pay attention to the training of managers to avoid brain drain.
In a word, the construction of campus network is a high-input project, and we should strive to achieve "high efficiency and high output" to make the management, education and teaching of the school embark on the track of information modernization. In the reform of school management, education and teaching in modern schools, we should give full play to the role of campus network and make our school walk in the forefront of peers.
