Henan Education Research Backbone Network Application Case

With the rapid development of modern information technology, Chinese education is advancing its own informatization level at an unprecedented speed and intensity, in order to realize computer teaching and distance teaching, and enhance the country's overall education level. At present, projects such as campus network, education metropolitan area network, and education resource center are under planning and construction in full swing across the country. National education authorities at all levels have given strong support to this, and have made detailed arrangements from development plans to policy guarantees. Early campus networks only shared internal educational system host resources, shared simple databases, mostly based on layer 2 switching, and rarely had layer 3 applications. There were problems with network security, and they did not have value-added management capabilities. Now the campus network construction needs to realize all-round internal data sharing, application of three-layer switching, provide comprehensive QoS guarantee services, make the network safe and reliable, so as to realize education management, multimedia teaching, library management automation, but also through the Internet to achieve remote Teaching, providing value-added and manageable business. The popularization of Internet applications will bring about unprecedented changes in the development of education. The Internet has broken the time and geographical constraints faced by traditional education, and has realized the dream of providing lifelong education and training for everyone in the whole society.

Henan Education and Research Network came into being in this context. Henan Education and Research Network (HNERNET) is the provincial network of China ’s Education and Research Computer Network (CERNET) in Henan. It provides access to CERNET and INTERNET for educational and scientific research institutions in the province. It has become the second largest Internet in China in CERNET. Today, the construction of the provincial education and research network has become particularly important.

As the backbone of our province ’s educational information network, Henan Provincial Educational Backbone Network takes into consideration the forward-looking, advanced, mature and good price-performance ratio in the choice of technology during network construction, based on the scalability and manageability of the network , Unified planning, step-by-step implementation, to meet the requirements of telecom operator-level networks, to ensure that the network is efficient, reliable, and secure, to ensure rapid business development and effective control, and user billing, management, and truly achieve "manageable, Value-added ".

After the "Education Informatization Year" plan was launched in Henan Province in 2001, Henan Province began the first phase of the construction of the province's educational backbone network, connecting it from Zhengzhou to the China Education Network (CERnet). Kaifeng and other sub-centers. However, with the further development of education, school-school communication, and Internet business, the province ’s demand for education informatization has been further strengthened. The original network can no longer meet the growing demand, and the existing network scale cannot fully cover the entire Henan Province. , Which greatly affected the development of informatization education, so the establishment of a new branch center on the original basis, covering the entire second-phase project construction in Henan Province started quickly.

For Henan Education and Research Network, while requiring high-speed connections, it must also be able to ensure the maturity of the technology and the stability of network performance. Because for a province-wide network, once an error occurs in the choice of schemes and main equipment, it means that the entire project will be affected, and the loss will be very large, so it must be treated with caution, so the Provincial Department of Education through public bidding , Strive to obtain a complete network solution with higher cost performance. In the bidding process of the province's network construction solution, Huawei Technology Co., Ltd. proposed the use of NE80 backbone routers to construct Henan education based on the existing education network in our province and our suggestions, as well as the construction goals of the second phase of the project. The second phase of the backbone network project, and became the second phase of the Henan scientific research backbone network with the "high cost performance, high reliability, manageability, and value-added" education backbone network solution, complete network structure, mature technology, and high-performance products. The ultimate choice for construction.
The specific networking of the second-phase project construction is shown below:

The core router in this networking solution provides rich routing protocol support and policy routing management functions, supports MPLS switching, has the characteristics of high speed, broadband, intelligence, reliability, and flexible networking, and supports multicast services and MPLS-based traffic engineering ( TE) and VPN applications, together with the high- and low-end router series products, broadband access series products, LAN-SWITCH products, and transmission series products that Huawei has launched, form a complete network from the access network to the core network The solution provides us with a more customized and business-specific network.

Quidway NE80 high-speed router is a high-end network product independently developed by Huawei Technologies Co., Ltd. for operation networks and backbone core networks. It uses a passive backplane with a backplane capacity of 256G and a maximum switching capacity of 128Gbit / s. It is positioned to meet the growing Internet. Business needs for backbone network equipment. Its carrier-grade reliability, wire-speed forwarding performance, perfect Diffserv / QOS mechanism, and rich service processing capabilities make it extremely suitable for Internet backbone network construction and metropolitan backbone network ) The need for construction.
