Application Case of Huawei 3Com in Campus Network of Yantai University

Yantai University covers an area of ​​3200 acres and a campus construction area of ​​506,000 square meters. It is a provincial key comprehensive university in Shandong Province that combines science and technology, arts and science penetration, and a full range of disciplines. In recent years, Yantai University has always insisted on teaching as the center, put the improvement of teacher quality and student comprehensive quality first, determined to carry out education reform, and pursue development with characteristics, which has formed a good school spirit of rigorous academic study, hard work, and strict discipline. , Has achieved a number of scientific research results and repeated awards.

The campus network of Yantai University is a batch of campus networks built earlier in China, and the backbone of the 155M campus network is constructed using ATM technology. With the continuous increase of network demand and the continuous progress of technology, the campus network has undergone tremendous changes in both scale and capacity. Therefore, the new campus network construction must not only consider the maturity of the technology, but also must consider the service carrying capacity and scalability of the network, so as to meet the increasing network demand.

Networking solution

This network construction is based on the principle of efficient performance and effective preservation of the original network resources. In the selection of equipment, Huawei 3Com ’s Quidway® S8512 10 Gigabit core switch, Quidway® S6506R and Quidway® S3000 series Ethernet switches are used to form Yantai University campus network.

The core layer uses three Quidway® S8512 10 Gigabit core switches, of which dual 10GE bonding is used in the old campus to build a 10 Gigabit bandwidth campus network backbone switching platform. The aggregation layer uses the high-performance Gigabit switch Quidway® S6506R, which can not only improve high-density user access, but also use 10GE interfaces to connect with core equipment when needed, thereby further improving the quality of the campus network.

In order to further improve the switching efficiency, the overall network adopts a flat design idea. For important users, they directly access the core switch, and some centralized user groups access the aggregation equipment nearby. The access layer uses Quidway® S2000 and Quidway® S3000 switches that provide perfect campus network access control and network services.

In general, the campus network of Yantai University not only has high bandwidth, but also has high data exchange efficiency. It is a campus network with advanced architecture and high performance. See the network diagram below:

Network characteristics

1. High performance

The core equipment of the campus network project of Yantai University uses Quidway® S8512, a 10 Gigabit switch from Huawei 3Com, to build a TBits-class campus network switching platform. Quidway® S8512 has 1.8T backplane switching capability and 450Mpps packet forwarding capability. At the same time, Huawei 3Com has enhanced Quidway® S8512's business support capability, and supports fully distributed business processing from the hardware structure to distribute business processing Each interface card, each line card contains a powerful Packet Engine, which can process Layer 2, IPv4, MPLS / VPN, IPv6 and other packet forwarding at line speed. It can be said that Quidway® S8512 finally achieves the beauty of harmonious business and performance with its powerful business processing and support capabilities. It is particularly important that Quidway® S8512 adopts a new 10 Gigabit switch architecture instead of a simple Gigabit switch improvement. Therefore, the campus network of Yantai University not only meets the current network needs, but also faces a future network. Can play a high-performance campus network for a long time.

2. Strong expansion and compatibility

10G applications do not mean that the network is flashy. Huawei 3Com's 10 Gigabit campus network solution not only meets the growth of backbone bandwidth, but also meets the needs of both business and performance, and meets the needs of network reliability. The most important thing is to enable users to obtain the minimum total cost of ownership (TCO). . The S8512 has a backplane switching capacity of 1.8T and can be expanded to 3.6T. At the same time, S8512 has 720G switching capability and can control capacity to 2.88T. In addition, 8512 not only has high-density service interfaces, but also provides rich service support capabilities, whether it is IPV6, WEBSWITCH, IPS or NAT and other services can be perfectly provided. In general, S8512 can meet the needs of campus network business, users, and bandwidth development for a long time, and it can conveniently and efficiently continuously improve network processing capabilities and protect existing investments.

Networking benefits

The construction of 10 Gigabit campus network will make Yantai University no longer face the shortage of bandwidth, especially the shortage of core network bandwidth. In particular, it guarantees the uninterrupted FTP applications, scientific research activities, online video and other network services that consume a lot of network bandwidth for a long time, improves the application of online teaching, E-Learening and other services, and becomes the cornerstone of Yantai University's expansion of information education.
