Concord Bilingual Optimizes Multi-line Access to Improve Network Teaching Quality

User profile:

Concord Education Group has a total of six Concord Bilingual Education School Districts and more than 20 bilingual kindergartens in Shanghai. In addition to the three-line access of the central campus, multiple subordinate campuses use dual-line access of telecommunications and education. All lines are connected by optical fiber, and the outlet bandwidth is between 8-50M to ensure the normal resource access needs of teachers and staff.

Facing problems:

Although it uses dual-line access, in practical applications, according to the reaction of teachers and staff in various campuses, due to the high utilization rate of video resources and online interactive courseware due to the teaching needs, the network bandwidth is severely blocked, and the normal teaching needs cannot be met at all. There are suggestions to increase the demand for line access or to widen the line.

The information department of Bingfeng Network and Group Center found that the problem did not arise from the bandwidth itself, but from the usage habits of most faculty and staff, making all kinds of application data access Internet resources through educational lines. Data access on the line is unimpeded. However, in some campuses, the telecommunication lines are occupied too much, making the education lines extremely idle. This kind of situation is especially obvious in the teaching period.

solution

Knowing the problem, Bingfeng Network has customized the smooth solutions of different application strategies for each campus of Xiehe Bilingual through link load balancing and traffic management technology, in order to meet the line needs of online real-time teaching and teaching staff.

1. Deploy the Bingfeng link load balancing device at the exit of the external network, connect the two external network lines, and configure the link balancing strategy and link priority strategy on the devices respectively according to the needs of the school district. For non-critical business applications, online reference video resources such as Youku and Tudou are shunted to the telecommunications link, while for teaching critical business resources, their bandwidth ratio on educational lines is guaranteed. It is also possible to preferentially select an idle line for access based on the line redundancy.

Second, divide the network segment of each building, department, department, and room, and adopt the grouping strategy, time strategy, and URL strategy to perform hierarchical and decentralized management on the line usage of each unit. For example, during the teaching period, priority is given to ensuring access to online interactive courseware in the classroom, green network filtering of instant messaging software and URL access to students ’Internet access, blocking or reducing the proportion of dormitory traffic.

3. Object-oriented management, providing an access mechanism based on the responsibilities and rights of the teaching staff, restricting access to terminal equipment, and adopting speed limit management for temporary users to ensure that users who are not within the scope of authority have excessive bandwidth resources and hinder normal Teaching application.

4. Provide real-time graphs and records of traffic and link usage to standardize the risk intrusion of real-time teaching and bandwidth resources by various applications, respond to emergencies and large traffic at any time, and ensure the normal teaching order.

Effect review

The project has been tested and launched one by one by the campuses of the Concord Group. The testing process was completed by the teachers of the information departments of each campus and the Bingfeng engineers. From the trial report, the network of each campus is running well, the various indicators have reached the expected results, and the speed of dual-line resource access has increased significantly. As of the time of publication, the Hongqiao Central Campus and Wanyuan Campus have taken the lead in completing the test cycle and entered the practical stage. Through the implementation of link balancing and traffic smoothing strategies, the problems of dual lines and insufficient bandwidth have been effectively resolved.

It is understood that the group will further develop beyond Shanghai, and Bingfeng will continue to create safe, stable and controllable information security solutions for the group.
