Boda supports the construction of Taian Education Network

Foreword

The development trend of modern education requires the establishment of a modern education and teaching network that serves quality education and adapts to the needs of future talents, and builds an education information network that faces the 21st century, covers the whole country, and connects internationally, with the education data center as the core; Taking the cultivation of a new generation of people with innovative consciousness and practical ability as the foothold, starting from "network building, database building, team building", to create a good campus network and distance education network environment, so that the construction of education informatization achieves leap-forward development, Lay a solid foundation for the development of education modernization.

demand analysis

Tai'an City Education Commission actively promotes the construction of a modern education system. It plans to build a modern education information network with the education committee as the core and covering the whole city. It provides diversified excellent teaching information sharing, or other large amounts of knowledge information sharing, and makes full use of the resources of the Taian Education Network. Substantially improve the teaching level of the entire Taian City. At the same time, it also provides a modern and convenient teaching management method to realize the unified and centralized management of the subordinate school districts and subordinate schools by the Education Commission, and can implement the national policies and policies on education in a more real-time and better manner.

The overall construction goal of Tai'an Education Information Network is: Education Information Network will be a unified dedicated information network. During the construction process, unified planning, unified construction, and unified management will be conducted for all school district networks; full use of existing resources will be used to build a dedicated educational information network.

At the same time, the built network is a comprehensive service system that integrates teaching, management and information release. It can adapt to the requirements of various applications, complete various forms of information transmission functions, and integrate text, data, tables, images, voice, and video. Communications, to achieve multi-purpose network, to avoid repeated construction.

An Introduction

The entire Taian education network system adopts a two-level structure of the backbone network and each school subnet. In the design of the network, the gigabit backbone between the education committee center and the campus, the gigabit backbone between the buildings, and the 100mb to the user's desktop are used. . The entire education network adopts a gigabit backbone for each elementary and middle school to connect to the Municipal Education Commission, each elementary and middle school uses a gigabit connection to each teaching building, and a 100M to desktop connection. The transmission media of the backbone network between the audio-visual building (network center) and other floors in all primary and secondary schools all use optical fiber, and select Gigabit Ethernet technology for networking. The network center is connected to the branch nodes in each building with optical fibers, and then connected to each user through the switch of the branch nodes in each building. For buildings with a large number of users, the switch uses switch gigabit stacking technology. The Gigabit Ethernet solution has the advantages of low cost, good interconnectivity, easy upgrade, and simple networking.

The network topology diagram is as follows:

At the same time, the establishment of the education network provides high-quality, efficient and intelligent network services for daily office, VOD video on demand, multimedia teaching, courseware resource sharing, macro coordination and scientific decision-making of various departments of the school. The establishment of the education network can bring the superiority of online teaching to the fullest. Even if more users want to join the application of online education, the network bandwidth will not become a bottleneck.

Program features

High security and high reliability

Boda series switches have the function of limiting the maximum number of ports connected to the host, with a powerful ACL, supporting data filtering based on MAC address, IP packets, and application ports; the Ethernet interface implements multi-way binding through trunk technology to increase bandwidth utilization and Reduce system redundancy. Support VLAN division based on 802.1Q, all VLANs can be managed through GVRP, which not only increases the security of the network, but also improves the flexibility and controllability of the network. At the same time, the core switch S5308 uses dual power supplies and dual main control boards to maintain safe and stable operation of the network and minimize network risks.

High performance, full exchange

It can automatically detect and suppress broadcast storms, support the detection of IGMP messages, effectively limit the flooding of broadcast messages, and support full-duplex mode and half-duplex mode flow control. Advanced buffer management, support 802.1p protocol, 4 hardware queues per port, provide priority guarantee, support IP multicast and QoS. The network backbone connection adopts Gigabit or GEC bandwidth aggregation technology. The S5308 provides line-speed core layer 3 switching with 48G of backplane bandwidth; it uses Ethernet switching technology, 10M / 100M to the desktop, and the long-distance connection uses optical cable through 1000M Connect to the core switching network at a rate to facilitate quick access.

Manageable and easy to maintain

The education network system is relatively large, and the switches are distributed in various middle schools, and the systems of the middle schools themselves are also relatively complicated. This requires the switches themselves to have strong manageability.

The Boda switch can automatically measure the cable length and automatically identify straight-through cables and crossover cables. S2224 adopts cluster technology, supports any number of device stacks, uses unified IP addresses for centralized management, and saves address resources; can be managed through control ports, Web, SNMP, and other methods; can be software upgraded through TFTP or FTP; supports DHCP Server and relay functions, dynamically assign IP addresses; use standardized modules to effectively protect user investment.

Strong scalability

The system needs to adapt to the various stages of campus network construction, but also to meet the needs of low-cost expansion and upgrade due to technological development needs. And can meet the future development needs of distance education; has a good resource expansion and compatibility. At the same time, in the process of application, the school can continue to add and improve resources through the means provided by each product to establish a sustainable campus network.

Boda S5308 switches and S2224 switches have free Gigabit slots to provide low-cost Gigabit connections, with stronger expansion capabilities and performance; the use of Boda BD1000 series, cost-effective switches, providing 100M fiber slots , On the basis of protecting user investment, provide users with a high-speed, highly scalable network.

In order to provide services for the education industry in a targeted manner, Boda actively cooperates with the education management departments at all levels to do a good job in promoting the construction of education informatization, and together with users, implement the implementation of education informatization construction projects to maximize the solution The problem of capital investment by college users has solved various problems that have long plagued China's education informatization, such as funds, talents, technology, and services, thereby continuously promoting the in-depth development of domestic education informatization.
