After wide application of the first generation Internet, problems such as network security, network capacity, speed and mobility became apparent. Starting in the mid-1990s, many developed countries like the United States began to research the next generation Internet in an attempt to solve these problems. "Our nation has quickly caught up in the development of the next generation Internet and has made outstanding achievements. However, if we don't pay enough attention to these projects, we will lose our voice in this field," Professor Wu Jianping with Tsinghua University stressed in a recent interview with Outlook Weekly. According to Wu, with strengthened economy, improved technology and formation of an extensive domestic network consumption market, China has met the basic requirements for developing a large-scale next generation Internet. "The next two to three years will be a crucial period for development. We must be aware of the urgency to develop the next generation Internet."
