With the widespread use of Internet applications, the network experience requirements of the teachers and students are continuously increasing. Not only does the university IT department need to face the increasing number of mobile terminal devices, but also needs to use the advanced network architecture to promote service innovation. Faced with such challenges, the Southwest University of Science and Technology (hereinafter referred to as SWUST) has adopted Ruijie’s Simplistic Campus Network Solution to transform the campus network and used the open and integrated technical features of the simplistic network to create a smart campus network which meets the needs of the new era. 
The Mobile Internet Challenges Campus Network Upgrades with Triple STAs
With the history of nearly a hundred years, the SWUST has gone through an extraordinary journey of entrepreneurship, development and growth through challenges and several relocations, and has been selected as one of the 14 key institutions of higher education in the western region by the Ministry of Education. The continuous expansion of the university scale and the rapid growth of the number of mobile terminals have raised extremely high performance requirements for the existing core network and gateway. There are currently more than 34,000 students in the university with at least one terminal device per student. If a laptop, mobile phone and tablet are used per student, the network is required to support 100,000 STAs, which pose great challenges on the existing network.  
Increased Network Performance Supporting 100,000 Concurrent STAs
The SWUST has adopted Ruijie’s network simplicity concept and network products to develop multi-operator cooperation and personalized mobile application platform. Not only does the solution provide teachers and students with ubiquitous online learning, integrated and innovative research environment, rich and varied campus culture, and convenient campus life, but also creates an efficient, stable, easy-to-manage and easy-to-use smart campus. 
First, there has been a qualitative change on the overall network performance. At the core layer, SWUST has deployed 2 RG-N18010 switches and has adopted the Virtual Switch Unit (VSU) Technology with 40G interconnection to virtualize two cores into one, achieving unified management and hot backup. The flat architecture and Ruijie’s RG-SAM+ authentication and accounting system have been adopted for the entire network. At the core layer, wired and wireless integrated gateway and authentication have been implemented. At the access and aggregation layer, QINQ encapsulation technology has been used to isolate the network and locate the terminals, supporting up to 100,000 concurrent STAs.
Secondly, by flattening the network, all the operation policies have been deployed on the core switches, eliminating the need for high maintenance workload on the access and aggregation switches. Not only does this save a large amount of investment costs and reduce workload, but also significantly simplifies the network operation and maintenance. Moreover, the flat platform built with Newton 18000 enables the open access of other wireless, aggregation and access devices without binding with any brand or technology, which provides loose coupling for subsequent product procurement. 
In terms of wireless network, the SWUST has adopted Ruijie’s scenario-based wireless solution to optimize different scenarios such as teaching, conferences, auditorium, dormitories and playgrounds, offering the ultimate Wi-Fi experience for end users. 
After implementing wireless coverage in 54 school buildings and 22 outdoor locations with more than 4,000 Ruijie APs, the SWUST has deployed the WIS platform, which serves as the radar and map of the wireless network, and has created the smart campus wireless network based on the high-speed wired network. 
In addition, Ruijie has also offered a variety of supporting network products:
  • The unified network management platform has enabled the SWUST IT Center to monitor thousands of network devices, more than 4,000 wireless APs, data centers and various IT resources in the campus network in real time.
  • In addition to unified authentication of the wired and wireless networks, the RG-SAM+ authentication module also supports flexible deployment of 802.1x and web authentication methods.
  • The gateway routers not only provide powerful performance, but also support other features such as flow control and load balancing, providing flexible and manageable network gateway solution. 
In the future, Ruijie will continue to support SWUST’s network to advance towards the path of openness and integration with comprehensive perception, seamless interoperability, elastic computing, massive data and smart management.
