Beijing Union University is a municipal university in Beijing. She uses the Xiaoying campus as the school's administrative and teaching center. It has 13 branches including the Business School, the College of Arts and Sciences, the School of Chemical Engineering, and the Special Education College. They are distributed in various urban areas and suburbs of Beijing, and there is also a Langfang branch. There are more than 30,000 students in the school, most of which are day students in Beijing. The number of students at Beijing Union University is relatively large in Beijing, and the decentralized campus is the biggest feature of the General Assembly.
In such a decentralized school environment, how to form a whole teaching system? The School Committee of Beijing United University has been thinking and demonstrating various feasible implementation plans.
In 1998, Beijing United University carried out the first-phase project construction of the campus network. It first connected 5 scattered campuses with ISDN and DDN dedicated lines to CERNET, which basically realized the information communication between the campuses. The interconnection bandwidth was 64K and 128K . However, most campuses do not have campus LANs, and some campuses have only teachers ’office networks.
Difficulties caused by dispersing school
Although this network has played a significant role, with the development of campus informatization, many problems have emerged.
At that time, the coverage of this network was too small. Because the teaching of each campus was independent, it could not form a whole interconnected teaching network.
Because the designed exit was too small at that time, the access speed was too slow, especially when accessing the Internet, and the waiting time was too long.
The school's informatization construction does not have the basic conditions for starting, and resources cannot be well shared.
Such a narrow-band network cannot transmit voice and video at high speed, and security cannot be guaranteed, so that online application services cannot be carried out.
Choose MPLS VPN
In order to solve these problems, after many comparisons and analyses, the General Assembly finally decided to cooperate with China Netcom to build an MPLS VPN private network. The General Assembly and China Netcom proposed a total solution (Total Solution) for the construction of the optical fiber interconnection of the General Assembly, and undertook the overall construction of the second phase of the campus network of the General Assembly. The school invested a total of 13 million yuan, and the overall planning and overall construction of the company. China Netcom is responsible for VPN network construction, network system integration and application system integration.
"Because MPLS VPN is a relatively advanced technology, before we adopt this technology, we made a careful and detailed comparison with other technologies," Zhang Liancheng, director of the United Network Information Center of the UN General Assembly, told reporters. "We have considered renting broadcasting or telecommunications. Bandwidth, but the network we want to build is not only access to the Internet, but more importantly, the overall information construction of the school should be built on this network. The school ’s office, finance, and teaching must rely on and rely on this network. This is a The overall online joint university. In addition, from the perspective of security and confidentiality, MPLS VPN technology is also the best. And the cost of using this technology is much more economical than laying optical fibers independently. "
Building a campus network
The campus network of Beijing United University adopts the planning policy of "overall planning and step-by-step construction".
The entire campus network includes 1 center and 8 campuses, which is called "one main and eight auxiliary" structures. The link resource used for interconnection and interworking in each school area is China Netcom's metropolitan area network fiber link, using the MPLS VPN service provided by Netcom. Each campus is connected to China Netcom Metropolitan Area Network through a 10M link, and the school center is connected to Netcom Metropolitan Area Network through a 100M link. With the help of the dual-loop structure of the metropolitan area network and MPLS VPN technology, the campus network of the United Nations University is formed into a logical topology The full mesh network topology is different from the common star topology. So to a certain extent, it can be said that the campus network of Beijing Union University is a metropolitan area network.
Compared with the campus network itself, the entire network takes the Xiaoying campus (the school headquarters) as the network center, which is the management center, information resource center, and information application center of the entire network, and it is also the Internet outlet. Other campuses can be regarded as branch sites, forming a star topology.
The entire campus network has a total of 4500 nodes. Each college adopts Gigabit Ethernet technology, using the core layer, aggregation layer, and access layer models to build a relatively independent "Gigabit to floor, 100M to desktop" campus network structure, based on the actual business needs and information applications of each college Demand, build their own proprietary information network centers to provide targeted network services and network application content; build a college-level network management center to provide services for the management and maintenance of our network facilities.
At the same time, each campus network is not completely independent, and they are the hierarchical structure of the master-slave relationship with the UNU campus as the core node. Because in the school headquarters, not only are all kinds of basic network applications for all colleges and universities, but also unified applications such as DNS, MAIL, FTP, etc., as well as information resource centers for various campuses. These resources cover office, educational affairs, Teaching, financial management, library management and other aspects. At the same time, the school headquarters has built a network management center for the entire campus network, implementing a centralized-distributed network management function for the "one main and eight auxiliary" network system.
On the equipment, Avaya's campus network products are used, and a complete set of solutions provided by Avaya is used.
Integration of resources shows power
Speaking of the current campus network situation of the UN General Assembly, Director Zhang said: "China Netcom has provided us with a 7 × 24-hour uninterrupted service, data, voice, and video all-round business, especially not only the colleges and universities The connection of the school headquarters, and the various colleges can also communicate
