Nanjing First Kindergarten campus network adopts typical star architecture design. By adopting NETGEAR high-performance M6100 and JGSM7224 switching equipment, it builds a set of Gigabit backbone and Gigabit to desktop solutions for users. Based on centralized management 600M The WLAN network provides unified security access management and policies to meet the needs of multiple applications such as mobile teaching. The UCNS1500 platform implements real-name management and control of IP addresses and campus wireless network security access authentication, while avoiding traditional wireless. Password leakage caused by network password authentication.
User profile
The No. 1 Kindergarten in Nanjing is an educational kindergarten with a long history and profound educational and cultural heritage. It is a demonstration experimental kindergarten in Jiangsu Province and a modernized kindergarten in Jiangsu Province. It is a provincial, municipal and district-level teaching and research base, and the base of the Sino-US Research Center of Nanjing Normal University. Founded in 1949, it is the earliest and largest school in Nanjing to build a full-time and day-care kindergarten. (The first kindergarten in Nanjing was originally the largest Wenzheng Academy in the Qing Dynasty in 1890, and the last champion of the Qing Dynasty was Zhang Yiren. Long; in 1914, Nanjing Middle School in Jiangsu Province became the cradle of cultivating party and government leaders; in 1947, it was the Children's Welfare Experimental Zone (headquarters); on September 1, 1949, it was established as the municipal entrusted child's office and the municipal government's first kindergarten, becoming a foster motherland. The cradle of flowers; in 1956 changed its name to the first kindergarten in Nanjing.

Technical solutions
1. Campus cable network design
The wired network adopts the star-level secondary network architecture. The campus network core switch M6100 and the access switches on each floor use Gigabit fiber connection, and the access layer switch uses the next-generation high-speed Ethernet switch JGSM7224 to provide users with Gigabit access. Gigabit uplinks to meet the maximum throughput you need in any situation. Network design for the entire project
The most investment-protected high-speed network infrastructure, which can be smoothly upgraded to a 10 Gigabit backbone in the future, can fully support the next-generation network data, voice and video integrated multi-service network platform. Support the performance and scalability required for cloud computing and other IT applications.
2, wireless network access layer switch design
In the access layer of each building group floor, the POE network power supply switch is used to provide power supply and data transmission for the wireless APs on each floor. The POE switch has high return on investment and is a network facility that provides high reliability and integrated voice. Ideal for video and data services.
3, wireless network centralized management and control design
For campus wireless coverage, we offer a thin AP solution, all APs are centrally managed through the wireless controllers in the network center. Therefore, in this solution, a set of Gigabit intelligent wireless controller WC9500 is deployed in the network center to control the APs in the network to achieve zero configuration of all APs.
4, wireless network access design
Considering that the wireless network adopts the traditional password authentication method, there may be security risks, which can be easily cracked or leaked. All the wireless networks designed this time adopt the wireless network security access mode and deploy one on the core switch. The access device UCNS1500, before the new user accesses the wireless network for the first time, must be authorized by the school to grant access to the new access device. (The next time the device needs to access the wireless network, it can achieve non-aware authentication. Otherwise, if the user is deemed to be an illegal user without being authorized, it will be placed directly in the wireless network quarantine area, and the IP address of the quarantine area will be obtained, which solves the security risks caused by the school password authentication. The tedious change of passwords on a regular basis.
5, data storage design
For the storage of internal data in the campus, the same IP storage ReadyNAS4220X can be deployed in the network center, which can provide both NAS and IP SAN, and can guarantee the smooth upgrade of storage capacity in the future. The ReadyNAS4220X has two 10 Gigabit electrical ports to ensure sufficient network connection bandwidth. Requirements, corresponding to video, traditional file data (unstructured data), we can create a separate volume storage on the storage; corresponding to WEB applications, mail, OA and database, etc. We can logically divide the certain space above the storage by means of SAN Provide the server with a storage backup of these structured data.
