在教育信息化浪潮的推动下,校园网广泛播种、飞速建设,但信息技术的发展和更新却远远超出我们所能预见,它使得传统有线校园网络的建设和应用的片面性逐渐呈现。新时期,如何对校园网进行升级、拓展及深层次应用成为当前校园网建设和改造要考虑的重要问题。 Driven by the wave of education informationization, the campus network has been sown widely and has been built rapidly. However, the development and updating of information technology have far exceeded what we can expect. This makes the construction and application of the traditional wired campus network gradual. In the new era, how to upgrade, expand and apply the campus network has become an important issue to be considered in the current campus network construction and renovation.
