Internet的发展与应用推动了信息技术和人类文明的进步,并由此产生了良好的经济效益和社会效益。但Internet的高速发展也表露出了它的一些不完善之处:随着用户数的激增和在商业上的广泛应用,网络拥堵日趋严重;Internet的商用化给科学研究带来了一定的负面冲击,也影响到了美国“国家信息架构”(NII)所制定的“为全体国民提供服务”目标的实现。美国人首先感觉到了应该有一个新一代的互联网来满足他们的需要,并由此提出和实施了新一代的Internet 2(简称I2)建设计划,此项工程在美国已全面铺开。
The development and application of Internet has promoted the progress of information technology and human civilization, and has produced good economic and social benefits. However, the rapid development of the Internet also shows some of its imperfections: With the surge in the number of users and the widespread commercial application, the network congestion is getting worse; the commercialization of the Internet has brought some negative impact on the scientific research , But also the realization of the goal of “providing services to all citizens” formulated by the U.S. National Information Architecture (NII). Americans first felt that there should be a new generation of the Internet to meet their needs, and thus proposed and implemented a new generation of Internet 2 (referred to as I2) construction plan, the project has been fully rolled out in the United States.
