Wuhan University intended to build a sizable Wi-Fi network by Ruijie

In 2015, Wuhan University intended to build a sizable Wi-Fi network across the dorm area and reform the campus and dorm wired networks' authentication and accounting systems. This strategy aims to successfully integrate wired and wireless networks and optimise the network architecture to increase the effectiveness of operation and maintenance. Network Ruijie See how they accomplished it; they did a terrific job on this project.

About the University:
Wuhan University, one of the essential universities under Project 211 and 985, is run by the Ministry of Education. Around 50,000 full-time students are now enrolled at the institution, which includes the faculties of humanities, science, engineering, information sciences, and medical sciences.

 

Project Background:
Wuhan University plans to build a sizable Wi-Fi network over the dorm area in 2015 and update the campus's wired network, authentication, and accounting procedures. 


To increase the effectiveness of operation and maintenance, this plan sought to integrate wired and wireless networks and optimise the network design. 


The user experience would be significantly improved while several issues would be resolved, including the slow pop-up portal authentication page, the disconnecting of wired users, outdated core and aggregation devices, the difficulty of maintaining the numerous access devices, and multiple authentications and accounting systems.

 

Solution:

  1. At the core, there are two RG-N18010 switches installed, which use the VSU technology to achieve virtualization and merge the two core switches into a single switch with unified management and hot standby. 
  2. With the help of VSD technology, the core VSU separates the physical core switches into a number of virtual core switches, enabling a centralized gateway and authentication for the wireless, office, and dorm networks, respectively, as well as control of logical separation and security isolation. It is possible to restart and manage each virtual switch separately.
     
  3. To accomplish the standard access configuration and user isolation, the Faculties of Humanities, Science, Engineering, Information Sciences, and Medical Sciences have deployed 5 RG-S8607E Aggregation Switches and more than 100 RG-S2910-24GT4XS-E Switches.
     

Customer Values:
Offering an Open and Integrated Platform

There is no coupling between the authentication system and wired/wireless devices thanks to Ruijie's RG-MACC-SAM, which combines the three existing authentication and accounting systems, and the RG-N18010, which integrates the authentication of the wired and wireless networks. 


This opens the door for equipment from other vendors to connect with the university's authentication and accounting system.


Significantly Elevating the User Experience

  1. Ruijie's exclusive portal noise reduction technology and the centralised authentication of the high-performance RG-N18010 Core Switch enable the quick pop-up portal authentication page.
  2. To properly isolate security concerns like Layer 2 broadcast and ARP spoofing, the RG-N18010 flattens the network and isolates each port and user of the network using QinQ. This solves the issues of network disconnections and interruptions.
  3. Users have various flexible authentication options to select from, including portal, 802.1x, and PPPoE, for a much simpler and more scalable user experience that also lessens user authentication issues.

Greatly Reducing Maintenance Workload

  1. To implement wired and wireless authentication throughout the entire campus, the institution only has to manage one RG-N18010 device and one authentication and accounting system. The maintenance workload has been drastically reduced as compared to numerous prior authentication and accounting systems, as well as wired and wireless authentication devices from other manufacturers.
  2. The access device uses Ruijie's streamlined configuration tools and the VLAN 1–24 standard configuration to achieve plug-and-play and reduce the labour associated with managing the access and aggregation devices.

 

Project Highlights:
The flat network architecture is used by Ruijie's Simplified Operation Solution to minimize the cost of aggregation and access devices as well as the maintenance effort of the access network, which considerably lowers the need for labour and time.

 

Customer’s Evaluation:
The open, highly compatible network architecture that boasts a better connection speed and fixes the disconnect issue is impressive. We particularly like Ruijie's post-sales team's professionalism, which guarantees a seamless network migration and satisfies our specific needs.
