Pudong is the leader of Shanghai's reform and opening up, and informatization of basic education is one of the most important tasks of Pudong New Area. As the most important component of Pudong's basic education informatization-Pudong New District Education Information Network provides comprehensive services including data, images, and voice for more than 200 primary and secondary schools in the district, and has realized the schools and Shanghai Education Information Network. High-speed interconnection. Pudong Education Information Network has built an informatization platform with international advanced level for the promotion and application of modern education technology, which has created conditions for the leap-forward development of basic education.
Network construction needs and goals:
Pudong Education Information Network connects a large number of information points in its subordinate primary and secondary schools including teaching buildings, office buildings, laboratory buildings, libraries, etc. It needs to carry out school management, education and scientific research, e-learning, distance education and the introduction of the Internet and external technical exchanges and A large number of services such as cooperative services require that the network must be a practical, highly reliable, efficient, highly scalable, and highly secure system.
High reliability In order to maximize the normal operation of the education information network system in Pudong New Area, high-reliability network products are selected in the network design, full consideration is given to the fault tolerance and redundancy of the equipment, the network architecture is reasonably designed, and reliable Network backup strategy to ensure that the network has the ability to self-heal.
Technical advancement and practicability While ensuring the satisfaction of campus business and application system business, it reflects the advanced nature of the network system. In the network design, the advanced technology is combined with the existing mature technology and standards, and the current status and future development trends of network applications are fully considered.
High-performance Backbone network performance is the basis for the good operation of the entire network. The design must ensure high throughput of the network and equipment, ensure the high-quality transmission of various information (data, images), and ensure that the network does not become a bottleneck for business development.
The openness of the standard supports the open protocol standards such as internationally common network protocols and routing protocols to ensure smooth connection and interoperability with other networks (such as China Education Network, Public Data Network, and schools, etc.) Good scalability in the future.
Flexibility and scalability According to future business growth and changes, the network can be smoothly expanded and upgraded to minimize adjustments to the network architecture and existing equipment.
Manageability Implement centralized monitoring and decentralized management of the network, and uniformly allocate bandwidth resources. Select advanced network management platform, with management of equipment, ports, etc., can carry out statistical analysis of flow and provide automatic alarm of failure.
Security Formulate a unified network security strategy and consider the security of the network platform as a whole. Ensure that key data is not illegally stolen, tampered with or leaked, so that the data has extremely high credibility.
Compatibility and economy Compatibility is reflected in the ability to maximize the availability and continuity of the school ’s existing computer software and hardware resources. Economic efficiency is reflected in the full utilization of existing resources, minimizing the overall investment of the network system, implementing network construction in a planned and step-by-step manner, and under the premise of ensuring the overall performance of the network, making full use of existing equipment or doing necessary Upgrade.
Key products:
Quidway S5516, S3526, S3026, S2403H, R2621, network management platform Quidway IManager N2000 serves more than 200 primary and secondary schools in Pudong New District.
Network construction plan and characteristics:
The Pudong Education Information Network logically adopts a star-shaped networking method, with the Pudong Education Information Center as the logical center of the entire Pudong campus network. Primary and secondary schools in the new area can access the new area information center through the operation of the mall area network, and the information center will be unified Join the backbone network of Shanghai "School to School".
All primary and secondary schools are logically connected to the Pudong Education Information Center through the operator ’s broadband line. Taking into account factors such as network construction costs, line resources, network expansion, and security, each school uses Huawei ’s R2621 router to access information through the operating mall LAN In the center, the campus network uses S5516 as the convergence device, and S3026 as the floor access switch.
1. Good interoperability: This project uses the IP basic network of Shanghai Telecom as the carrier platform, and provides products that are fully compatible with the Shanghai Telecom IP platform through Huawei ’s mature technologies and products.
2. Flexible networking: Since Huawei can provide a full range of routers, Ethernet switches, IP telephone gateways, videoconferencing systems, gateways, access servers and other products, it can meet the individual networking needs of each school when networking , And laid the foundation for the integration of data, video, voice and other network services.
3. High performance: Huawei provides network products with high performance, three-layer switching, multiple backup strategies, smooth expansion, control, and line redundancy backup. Access layer products such as full-line speed Layer 2 switches and Ethernet access equipment have the characteristics of supporting multiple services, unified access to multiple ports, high cost performance, multiple authentication / billing methods, and manageability.
4. Unified management: Through Huawei ’s Quidway series unified network management platform Quidway IManager N2000, network equipment in the whole area can be centrally managed in the same network management center, and appropriate management authority can also be assigned to lower-level schools, greatly reducing network maintenance The human and material resources have saved more energy to invest in the construction of educational informatization.
Business benefit realization:
Pudong is the leader of Shanghai's reform and opening up, and in the future about 50% -70% of Pudong's builders and laborers will grow up in the current primary and secondary schools. Today's basic education directly determines the basic qualities of a new generation of builders, determines the future of Pudong, and determines the speed of modernization of Pudong. Therefore, the construction of Pudong School-School Communication Network provides an informatization platform with international advanced level for fundamentally fighting the WTO, realizing the leap-forward development of basic education and comprehensively promoting quality education, and has contributed to the construction of Pudong informatization!
