User profile Sun Yat-sen University is a famous institution of higher learning with a good tradition of running schools in China, and an important base for talent training and scientific research in China. In 1924, Mr. Sun Yat-sen, the great man of the century, founded this university. After decades of construction, Sun Yat-sen University has now become a domestic first-class institution of higher learning with a full range of disciplines and a complete education system for cultivating bachelors, masters, doctors and post-doctors. In September 2004, with the support of the Guangdong and Guangzhou municipal governments, the East Campus of Sun Yat-sen University was officially inaugurated in Guangzhou University City, Panyu District, Guangzhou City, further expanding the space for running schools, adding new advantages for starting schools, and improving the level of running schools. Floors. Project Background In the first phase of the construction of the campus network of the Guangzhou University City of Sun Yat-sen University, Huawei 3Com has long understood and grasped the needs of the education industry for high performance, easy management, and business richness. It coincides with the needs of the school and uses unified network equipment. The overall solution of the whole network has realized the diversified broadband connection between the campus network and CERNET, the campus, the university city junction center and other networks, which has improved the school ’s network export environment and reserved for future development. space. Due to the successful cooperation of the first phase of the project, coupled with good after-sales service and good industry reputation, Sun Yat-sen University still chose Huawei 3Com as a partner when implementing the second phase of the project. Networking solution In the construction of the second phase of the Guangdong University City campus of Sun Yat-sen University, following the overall design principles of the first phase, Huawei 3Com provides a TB-level switching platform 10 Gigabit education park network solution. The project adopts Quidway® S85 10 Gigabit core routing switch as the core backbone, provides up to TBits-level switching platform, business processing and support capabilities, and finally achieves business and performance matching, and can be gradually upgraded to ensure the long-term suitability of 10 Gigabit core. The aggregation layer uses Quidway® S8505 10 Gigabit core routing switch as a high-capacity 10 Gigabit switch to aggregate data streams, and the access layer uses Quidway® S3000 series Gigabit intelligent layer 2 switches specially developed for the education industry to provide cost-effective layer 2 access And management certification control. The network diagram is as follows: Network diagram Overall, the second phase of the project provided a network system integrating high performance, high scalability, and high security for Sun Yat-sen University. First, it provides a TB-level switching platform. As the core equipment, QuidwayS8500 can meet the switching capacity up to 2.88T, thus supporting the use of large-capacity 10 Gigabit ports in the core backbone. Its TBits-level structure and 10G interface chip can ensure that medium and large users will be able to meet 10,000 in the next few years. Demand for mega interfaces, and concurrent line-speed switching of ports. In addition, QuidwayS8500 also supports the application of IPv6 technology in the education campus network. You can enable the IPV6 function by upgrading the system software (QuidwayS8500's IPV6Ready board already supports the function of IPV6 in hardware), and in the stage of large-scale deployment of IPv6 services, through fully distributed services The interface board can realize distributed processing of IPv6 and realize wire-speed forwarding. At the same time, the core 10 Gigabit Layer 3 switch supports fully distributed service processing in terms of hardware structure, and can process Layer 2, IPv4, MPLS / VPN, IPv6 and other data packet forwarding at wire speed without the assistance of a central processing board. Providing a service interface board based on NP (Network Processor) can realize the high-speed processing capabilities of services such as NAT, FIREWALL, VPN, etc., which improves the performance of the business and solves the business support requirements of the entire network for the core equipment. Network characteristics This time, Huawei 3Com's integration of operational, manageable, and value-added design concepts uses high-end network equipment to build a network platform that focuses on business and performance for Sun Yat-sen University. Its networking also has distinctive characteristics. First, a high-performance campus network that can be expanded to 10 Gigabits: The East Campus network platform provides Sun Yat-sen University with a leading high-performance campus network that incorporates Huawei 3Com ’s operational, manageable, and value-added design concepts. The network can fully To meet the application requirements of teaching and experiment of Sun Yat-sen University and rich network application services. Second, the complex multi-export and billing requirements: the campus network export is connected to the China Education and Research Network (CERNET) export and the operator network export at the same time, so users are required to use different account names or use different domain names with the same account Certification, obtain the relevant access rights to the campus network, education network outlet or operator Internet outlet, and have the need to charge separately for different outlets, such as access to the campus network, education network outlet is not charged, access to the Internet outlet is subject to a certain fee Rate billing. Third, the needs of user management: The high quality of the campus network user group is easy to cause frequent network hacking attacks, often with address theft and user name spoofing problems; campus internal access traffic is huge, such as FTP file transfer and specific time (such as night ) Generate tremendous pressure on network equipment. Therefore, support for user authentication is required, and the problem of account and port binding needs to be solved; the device can control the user's bandwidth; at the same time, it is very common for many students to access the network through proxy software. How to ensure that network resources are not blocked Excessive occupancy and ensuring normal access to the school become the top priority. Fourth. Multi-service management support needs: One of the key objectives of campus network construction is to treat students as consumer customers and provide consumer Internet services to replace campus external Internet cafes. At the same time, colleges and universities have rich educational resources and are the main supporting force of public education. The development of paid resources based on the Internet is becoming the main form of public education, such as distance education. This not only revitalizes existing resources, but also adapts to the trend of education industrialization, and promotes the development of public welfare education through paid services. In addition, the network management is convenient and efficient: the information point of the campus network of Sun Yat-sen University is very large and the users are dense. This network can efficiently and conveniently manage each network device and user. Networking benefits The second-phase campus network of Sun Yat-sen University has been officially opened a few days ago. The QuidwayS8505 backbone routing switch produced by Huawei 3Com enables Sun Yat-sen University to implement multi-point simultaneous teaching in the region, distance education between campuses, dynamic address allocation for school premises Internet access and many other services suitable for campus applications , Which guarantees the uninterrupted FTP applications, scientific research activities, online video and other network services that consume a large amount of network bandwidth for a long time, and truly achieves the purpose of sharing educational resources. Smooth upgrade provides a guarantee. At a deeper level, the operation of the campus network has changed the traditional methods of student learning, teaching and research, and school management, and further laid an important foundation for discipline construction and academic development. It is a major leap in the development of Sun Yat-sen University's education informatization.
