As the country's first batch of "985 Project", "211 Project", "Double First Class" Class A world-class university construction universities, Southeast University is known as the "Holy Land of the Academy" and "The First Class of the Southeast University". After 115 years of development, today's Southeast University is accelerating the development of education informatization through innovative technologies. On the campus of Southeast University, a wireless network that is "anytime, anywhere and usable" has become the new name card of the school's smart campus.
Since the summer of 2006, the main teaching area of ​​Southeast University has been moved to the Jiulonghu campus, thus opening a brand new page in the history of school development. The increased campus area brings a better and more comfortable teaching environment, but it also brings new challenges and problems. With the advent of the mobile Internet era, the number of access devices in the hands of teachers and students is increasing, and the requirements for the network are constantly increasing. Schools are in urgent need of a new round of wireless network construction.
Optimizing the wireless program "Strength" to enter the new campus
In 2016, Southeast University Jiulonghu Campus began to redeploy the wireless campus. After repeated comparisons and selection, the school adopted the overall wireless solution of Ruijie Networks to cover the whole school. The solution uses the RG-N18010 (Newton Newton series) cloud architecture network core switch at the core of the wireless network, and the wireless controller uses the core switch card to achieve redundancy and reliability through the deployment of wireless controller virtualization.
On the Jiulonghu campus, Ruijie deploys wireless APs based on different application scenarios of the school. For example, the RG-AP740-I's latest 4-stream 802.11ac Wave2 standard wireless AP is used in the teaching building area to meet the needs of high-density environments in the classroom; campus offices use the Ruijie Smart + program, with one deployed in each office Micro AP, to achieve wireless signal coverage in the office, the micro AP of each building is managed by the building main AP, which greatly reduces the wireless management and maintenance work.
In 2017, the campus of Sipai Building of Southeast University also selected the overall wireless solution coverage of Ruijie Networks, and deployed the Ruijie Zhifen + (including micro AP), RG-AP520 (W2) indoor AP and RG-AP740-I high density AP.
In terms of operation and maintenance, Ruijie RIIL IT operation and maintenance management platform is adopted for the operation and maintenance of the entire network of Southeast University ’s Sipailou campus and Jiulonghu campus to realize the unified management and operation of IT resources such as wired, wireless, and server across the school.
Four advantages add luster to smart campus
After the Ruijie minimalist wireless network solution is adopted, the wireless network of Southeast University is extremely powerful in terms of performance and functions, mainly in four aspects:
First, the core is high-performance and stable, meeting the school's large concurrent traffic.
In the wireless network solution of Southeast University, the core switch RG-N18010 of Ruijie Networks adopts the advanced CLOS multi-level multi-plane switching architecture, which provides continuous bandwidth upgrade capabilities and business support capabilities. Backbone strength provides a stable and high-quality network access and Internet access space for teachers and students of Southeast University.
Second, all wireless APs are deployed in the room, with better signal coverage.
The signal on the campus office was not good because the AP was placed in the corridor, and the wall blocked the signal. After replacing the Ruijie AP, the in-room deployment solution was adopted to completely solve the signal strength problem and prevent frequent re-authentication caused by the frequent offline of user equipment.
Third, the scenario-based wireless product technology provides the ultimate experience.
Based on the scenario-based wireless design concept, using the mainstream 802.11ac Wave2 technology as the standard, Ruijie Networks provides a smart point + solution exclusively for office application scenarios on the campus of Southeast University. It supports a maximum of 1 point and 24 deployments, and is a dual-band dual-flow room- — Two streams of 867M for 802.11ac Wave2 and 300M for two streams of 802.11n fully meet the high-speed access needs of teachers and students of Southeast University. At the same time, for large-area, high-density scenarios, the solution uses Ruijie Networks' AP with smart antennas. One of its three radio frequency cards has a 5G radio frequency that can be flexibly switched between Wave1 and Wave2 to meet various campus requirements. The application requirements of the terminal. For ordinary classrooms, the solution uses a dual-channel dual-band 802.11ac Wave2 wireless AP and supports the industry's latest MU-MIMO technology, which can achieve parallel transmission of multiple terminals in a wireless multi-user concurrent environment, greatly improving wireless data throughput And multi-user access experience. The AP supports two spatial streaming technologies-2.4G provides an access rate of up to 300Mbps, 5G provides an access rate of up to 867Mbps, and the whole machine provides an access rate of 1.167Gbps. Its gigabit rate makes wireless performance no longer an application bottleneck .
Fourth, unified operation and maintenance of the entire network to achieve precise management.
Ruijie RIIL IT operation and maintenance management platform based on business visualization has helped Southeast University Jiulonghu campus and Sipailou campus to achieve unified IT infrastructure resource management, business value analysis, data center computer room environment management, IT operation and maintenance work and performance Management, etc., help administrators realize early warning and prevention before they happen, and can quickly locate problems and quickly troubleshoot afterwards, which greatly reduces operation and maintenance costs. At the same time, RIIL also provides rich graphic reports for IT managers, analyzes from various dimensions such as TopN, resources, faults, trends, etc., clearly presents the performance level and defects of IT infrastructure, and is related to the business, reflecting resources The impact and threats caused by the bottleneck on the business provide the original data of the information business system for the user's decision-making and work plan arrangement, so as to achieve the rational and optimal use of resources and achieve the purpose of precise management.
Ruijie good wireless: good experience comes from good products
Based on the advantages of traditional coverage solutions, Ruijie's minimalist wireless solutions have made bold innovations and ingenious designs for all links involved in wireless, and have continued to improve based on scene business requirements. Practice has proved that the Ruijie minimalist wireless solution makes the application and future expansion of the wireless campus network more powerful and rich from various aspects such as wireless coverage and wireless network bearer, helping universities realize wireless value-added and information center service transformation.
For the application effect of Ruijie wireless solution, the person in charge of informationization of Southeast University expressed great affirmation: "Using Ruijie's minimalist wireless solution not only allows all kinds of teaching, research, management and service on the campus of Southeast University The tens of thousands of wireless terminals can be quickly connected to the Internet, and the application experience is good. The management of the operation and maintenance personnel has also been greatly reduced, which has laid a strong network foundation for Southeast University to build a new generation of smart campus. "
Up to now, the Ruijie minimalist wireless solution has served Wuhan University, Sun Yat-sen University, Southeast University and other national universities. The share of 211 universities has reached 75%, becoming a veritable market leader in the education industry.
