School Networking Solutions

The main task of campus network construction is to basically achieve full coverage of the school Internet, full coverage of the teaching environment network, access bandwidth of 10M or more, multimedia classrooms accounting for 80 per cent of ordinary classrooms, and to promote the construction of digital campuses and smart campuses. Nowadays, full coverage of school Internet has become the development trend of schools.

1.Demand Analysis

(1) Network speed and network stability.

At present, the wireless campus network needs to ensure that each user can access the Internet fast and without dropping, and at the same time ensure that teachers and students can access the Internet green and safely.

(2) No dead angle of signal and no interference.

In the design process, the degree of difference between different teaching environments needs to be considered to ensure that the wireless network is smooth.

(3) Wireless campus network should support all kinds of terminals.

With the increase in the number of wireless devices with mobile capabilities, the wireless campus network design process needs to take into full account the smooth access of notebooks, mobile phones, iPads and other mobile terminals.

(4) Many types of equipment, management and maintenance is difficult.

For campus wireless network managers, in the process of designing the wireless campus network need to fully consider the convenience of equipment maintenance and management. For example, the unified online management of equipment.

(5) Network size (2000-4000 people).

gateway

HS -MAC2000

19-inch iron casing, multi-WAN access , and supports up to 2,000 terminals online at the same time. It is a multi-functional firewall router designed for enterprises, schools, Internet cafes, and rental houses that highlights Internet behavior management, bandwidth overlay, intelligent QoS, and integrated PPP0E authentication server.

Bandwidth superposition: Simultaneously access 7 ( can be expanded to 200 ) wide area networks, using multi-threading tools , you can achieve the superimposed network speed.

Line backup: When the main line goes offline, the backup line takes over to ensure smooth network operation.

Line distribution: Line distribution can be performed based on source IP, destination IP, source port, destination port, and domain name.

Policy routing: Simultaneously access different operators such as China Telecom and China Unicom to solve the embarrassment of north-south communication on the Internet.

Super powerful behavior management function

Block Xunlei, block games, filter Kaixin.com, control QQ chat and guide reasonable Internet access... Provide comprehensive professional online behavior management functions. Through the settings of IP groups and time groups, you can establish more flexible and user-friendly management rules to help you make good use of the network, manage the network well, and improve work efficiency.

Intelligent flow control

Intelligent flow control can analyze various conditions of active hosts in the network and automatically adjust the bandwidth. When the network is busy, small packets are given priority to ensure that other users can access the Internet smoothly; when the network is idle, segmentation allows users to break through the speed limit for high-speed downloads, effectively utilizing network resources. . The new QOS architecture is 5 times faster than the original QOS, and the web page is smoother. The new flow control module breaks through to the seventh layer of the network and can specify applications for management, restriction and rate limiting.
