-100G,100G the birth of China's first 100G backbone network backbones-IT information China's first 100G birth of backbone
One 2G capacity of information with 10G network download, about needed 16 seconds, with 100G network download only needed insufficient 0.2 seconds...... "China education and research computer network (CERNET) trunk network and focus disciplines information service system upgrade expansion works" December 31 in Tsinghua University through acceptance, marks my first a 100G trunk network birth, China education and research computer network also became world Shang scale maximum of 100G academic network.
Organization's acceptance of the Group of experts pointed out that the Ministry of education, the completion of the world's most advanced 100G high-speed transmission networks, Internet and the future for the next generation network provides the necessary transfer of technology innovation base.
With the development of the Internet, data age, both education and research, or economic life, increasingly high demand for Internet bandwidth, increasingly urgent demand for high-speed network. Backbone technology has experienced different stages of development, such as, 155M, 10G, all currently running 10G is the main Internet backbone network. 2013, some developed countries have started the planning and construction of the 100G backbone, educational scientific and academic networks to become leader.
In September 2011, "China education and research network, Cernet backbone and key subject information services system upgrading project" access to sectors of national development and Reform Commission, Ministry of education approval to start, CERNET 100G backbone network project formally began construction. It took 2 years, 38 colleges and universities work, and finally had my first 100G built the backbone. Expansion of capacity expansion of China education and research network, Cernet high-speed optical transmission network all using domestic equipment, covered 29 provinces, autonomous regions and municipalities in 34 cities, total length of 21732.4 kilometers, formed over more than 2000 colleges and universities the ability to provide high-speed access over Gigabit, of which more than 500 colleges and universities access to achieve Gigabit.
It is worth mentioning that, after upgrading the China education and research network backbone built cover 54 a distributed key subject information service system of the key disciplines, in higher education and science and technology innovation provides an important source of information.
China education and research network Director of the Committee of experts, Tsinghua University Professor Wu Jianping, Director of the Department said that the completion of the first 100G of backbone, not only in terms of network capacity and bandwidth, but also from the steps in the network security and management, for the development of teaching and research in colleges and universities in China provides important support, our education information infrastructure the first to reach the world advanced level.
中国第一个100G主干网诞生 - 100G,100G主干网 - IT资讯中国第一个100G主干网诞生
一部2G容量的资料用10G网络下载，约需16秒，用100G网络下载仅需不足0.2秒……“中国教育和科研计算机网(CERNET)主干网和重点学科信息服务体系升级扩容工程”12月31日在清华大学通过验收，标志着我国第一个100G主干网诞生，中国教育和科研计算机网也成为世界上规模最大的100G学术网络。
教育部组织的验收专家组指出，该工程建成世界先进的100G高速传输网，为下一代互联网及未来网络技术创新提供了必要的传输基础。
随着互联网的发展，大数据时代到来，无论是教育科研，还是经济生活，对互联网的带宽要求越来越高，对高速网络的需求越来越紧迫。主干网技术先后经历的了155M、2.5G、10G等不同发展阶段，目前各国运行的互联网主干网主要是10G网络。2013年一些发达国家开始着手规划建设100G主干网，教育科研学术网络成为领头羊。
2011年9月，“中国教育和科研计算机网主干网和重点学科信息服务体系升级扩容工程”获得发改委、教育部等部门批复启动，CERNET 100G主干网项目正式开始建设。历时2年，38所高校协同作战，终于建成了我国第一个100G主干网。扩展扩容的中国教育和科研计算机网高速光传输网全部采用国产设备，覆盖29个省、自治区、直辖市的34座城市，全长21732.4公里，形成了为2000多所高校提供千兆以上高速接入的能力，其中500所高校的接入能力达到万兆以上。
值得一提的是，升级扩容后的中国教育和科研计算机网主干网还建成了覆盖全国54个重点学科点的分布式重点学科信息服务系统，为我国高等教育和科技创新提供了重要的信息资源。
中国教育和科研计算机网专家委员会主任，清华大学计算机系主任吴建平教授说，第一个100G主干网的建成，不仅从网络容量和带宽，也从网络安全和管理上上了一个大台阶，为我国高校教学、科研发展提供了重要支撑，使我国教育信息化重要基础设施率先达到世界先进水平。
