Construction background
Yuehua No. 1 Middle School is the first batch of provincial key middle schools listed in Hunan Province. The school has modern teaching building, science and technology building, experiment building, library, gymnasium, student canteen, student dormitory, campus intelligent teaching bass broadcasting system, multimedia voice room and teaching room. How to achieve high-speed interconnection of all functional facilities and how Unified intelligent management has become an urgent problem to be solved in Yuehua No.1 Middle School. The goal of the construction of the campus network of Yuehua No. 1 Middle School in Hunan Province is to build a network environment that serves teaching activities, scientific research activities, and education management. Resources.
Project implementation
In response to the construction standards of the campus network, Hunan Yuehua No. 1 Middle School put forward the following six requirements:
1. High-performance full exchange, Gigabit backbone and redundant backup connection to meet the needs of heavy load network operation;
2. Support multimedia applications, including multimedia classrooms, electronic reading rooms, multimedia teaching and office automation;
3. Use the convenient management function of the virtual network (VLAN) to improve the security and performance of the network;
4. Mature multimedia application system to meet users' on-demand and broadcasting needs, and realize multimedia teaching and management;
5. The network management is simple and easy to use, no special training is required;
6. High-speed broadband private line access to the Internet to achieve high-speed access to the wide area network for all users in the campus network.
After a comprehensive investigation and comprehensive comparison of the programs, Yuehua No. 1 Middle School finally decided to use the network equipment and overall campus network solution provided by Ruijie Networks.
Ruijie Networks has carefully constructed an advanced, high-speed and intelligent campus network for Hunan Yuehua No. 1 Middle School from three levels: core layer, aggregation layer and access layer.
First of all, at the core layer of the network, Yue Huayi adopted the core backbone routing switch STAR-S6808 of Ruijie Networks. STAR-S6808 is a fully modular, high-density port backbone routing switch independently developed by Ruijie Networks. The number of Ethernet ports can be expanded by as many as 448. At the same time, it is equipped with 116 gigabit ports to provide unlimited upgrades for campus networks. Capacity expansion space; in addition, STAR-S6808 also has 8 expansion and rich function modules, which can be flexibly configured according to the needs of the campus network to build a flexible and scalable network.
At the network convergence layer, Ruijie STAR-S3550-24 Gigabit intelligent multi-layer switch is used. STAR-S3550-24 supports 2-4 layer network data exchange, while providing a complete intelligent flow classification and QoS function, provides the campus network with a wealth of security settings and network management based on QOS policy, to the greatest extent to meet the new generation The campus network needs high speed, convergence, and security.
In addition, the Ruijie Networks STAR-S1926F + enhanced network management access switch is selected at the network access layer. STAR-S1926F + has rich and powerful network management functions. It can perform network management operations on the network through multiple settings to achieve IP settings and VLAN ports. Various management such as settings, security control settings, static address management, broadcast storm control, port MAC address lock, priority, etc.
Program features
1. High-performance data processing capability. The core routing switch used by the system, Ruijie STAR-S6808, has a backplane bandwidth of up to 256G and a three-layer packet forwarding rate of 173Mpps, which can provide high-speed non-blocking switching for campus networks; aggregation layer switch STAR-S3550-24 and access The switches STAR-S1926F + are all wire-speed switches. The distributed three-layer network structure jointly constructed by STAR-S6808, STAR-S3550-24 and STAR-S1926F + enables the entire system to achieve extremely high business processing capabilities.
2. High reliability and easy maintenance. All switching modules of STAR-S6808 adopt distributed switching mode and have independent switching capabilities. In this way, even if the core engine stops working, each switching module can still continue to exchange ports on the module. At the same time, all modules of STAR-S6808 can be hot-swapped, which will not affect the normal operation of the switch when the module is replaced and expanded, and the failure recovery time of the device is greatly reduced.
3. Unlimited expansion of campus network. The STAR-S6808 switch chassis has 8 slots, which provides high-density modules for the network system, and also reserves sufficient space for the switch ports required for future expansion.
4. Manageable and high security. STAR-S6808 supports IEEE 802.1Q and a protocol for dynamically dividing VLANs. STAR-S3550-24 and STAR-S1926F + support the standard IEEE 802.1Q protocol for dividing VLANs; in addition, STAR-S6808 also has a super-routing function that enables data storage and forwarding across VLANs.
5. Rich multimedia applications. Ruijie Networks series switches implement end-to-end CoS / QoS services. On the one hand, the QoS (ToS) function of STAR-S6808 can analyze the TCP / UDP port number by hardware, classify and mark 802.1p and implement the control strategy. In addition, STAR-S6808 also supports multimedia application requirements for network bandwidth, providing a strong QoS policy support for campus networks.
Operation effect analysis
After the network system of Yuehua No. 1 Middle School in Hunan was put into operation, on the one hand, it fully demonstrated the advanced features, scalability, openness, security, manageability and rich applications of the overall solution. In addition, Yuehua No.1 Middle School Campus System 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 educational informatization level of Yuehua No. 1 Middle School has been further improved.
