Huawei Agile Creates New Campus Network System for Donghua University
Education is the foundation of the country. The cultivation of talents depends on the school. There is no doubt that the role of universities in the current Chinese education industry is irreplaceable.
Located in the international metropolis--Donghua University in Shanghai, it is a university directly under the Ministry of Education, the national "211 Project" and the "Excellent Engineer Education and Training Program". It is the first batch of doctors, masters and bachelors in China. One of the universities that grants three degree degrees.
The campus network is under stress and needs to be decompressed
At present, the number of students in the whole school has reached more than 40,000, and the number of peak online users has exceeded 30,000. The size of the students has been expanding, and new businesses such as social networks and MOOCs have emerged. The network built eight years ago is in performance and reliability. Convergence management and other aspects have been unable to meet the needs of business development, and it is urgent to build a new campus network. At present, with the increase in the number of students, the carrying capacity of the Donghua University network is also under tremendous pressure. Specifically, it includes the following three aspects:
1. The core node has no reliability guarantee: the original core and aggregation are single deployment. There is no equipment-level high reliability, no network-level reliability guarantee, and tens of thousands of campuses, once the problem occurs, the consequences are quite serious.
2. Wired and wireless users cannot be managed uniformly: Due to the inconsistency in the construction period of wired and wireless networks, the management of wired and wireless users is carried out through two sets of systems. The strategy cannot be unified and it is difficult to maintain.
3. The security situation of the whole network is unclear: teachers and students often reflect that the network is sometimes slow, but they cannot locate the source of the problem. Therefore, it is urgent to understand the security situation of the whole network.
Huawei helps Donghua University to build the next generation of fully connected agile campus network
In order to solve the above problems, Donghua University and Huawei have cooperated with Huawei's agile campus network solution to successfully solve high-reliability, unified management of wired and wireless users through 11 S12712, SDN Agile Controller and unified eSight eSight devices. Security visualization and many other issues:
1. First, the core adopts the CSS2 cluster. The control packets and data packets of the cluster system go through separate channels. Even if all the links between the switching networks fail, the control packets can pass through the control channel between the main control boards. Inter-device communication, the cluster system will not split, completely solve the reliability problem of the core node.
2. Secondly, through the BRAS feature of the Huawei S12700 and the user management of the AgileController, each board can provide 16K user management. The portal gateways for wired and wireless users are all placed on the aggregation switch S12712. Currently, the Donghua University campus The network system realizes the unified management of wired and wireless admission control, and does not need to pay attention to the lower-layer switches and the brand of the AP, thus completely solving the unified management problem under the various network scenarios existing in the campus network system of Donghua University. .
3. Finally, through AgileController's security coordination based on the big data concept, the logs of key equipments of the whole network are collected, classified, and strongly correlated, real-time discovery of dangerous existence and early warning, so that the east The entire network security map of Hua University has realized visualization, and comprehensively grasps the security posture of the entire network of Donghua University campus network. The network problems that teachers and students respond to can be solved in real time and effectively.
With the help of Huawei's agile network solution, Donghua University has built a reliable and efficient next-generation fully-connected agile campus network to achieve unified management of wired and wireless users, a unified access gateway and a unified user access strategy. Management and big data-based network security collaboration, the whole network security situation real-time perception, the establishment of this agile campus network can support the new business development of Donghua University in the next 5-10 years.
