Tsinghua University, with a history of 92 years, has 13 colleges and 49 departments. Its disciplines cover the fields of science, engineering, literature, law, medicine, journalism, management, and art. As an internationally renowned university, Tsinghua University advocates open schools and services to the society, and pays special attention to promoting the overall improvement of modern university education with informatization, thus building a road to take off. A few days ago, with the support of Cisco (China) Network System Co., Ltd., Tsinghua University successfully upgraded the campus network to 10 Gigabit using advanced technology, and it was at the forefront of the information infrastructure construction of famous universities in China.
Unified network is imperative
Tsinghua University was in contact with information technology earlier, and successfully developed the first general electronic digital computer in Chinese universities and opened the first BBS site in mainland China-"Shuimu Tsinghua" ... In the construction of campus information infrastructure, Tsinghua University built a The three-dimensional digital space finally realizes the comprehensive informationization of the education process.
The campus network of Tsinghua University was established and used in 1992. Initially, it was mainly used in laboratory and office environments. The location of the PC was relatively fixed, and user management and billing were based on IP addresses. In 1996, the campus network of Tsinghua University was upgraded to switched FDDI, and 11 routers installed in different locations connected more than 50 buildings on the campus. In 2000, the Tsinghua campus network was upgraded to Gigabit Ethernet, and the optical fiber has reached 140 buildings throughout the school. As long as there is a PC on the campus, you can choose courses online. And with the advancement of educational research network (CERNET), China High-speed Interconnection Research Test Network (NSFCNET) and other projects in Tsinghua, Tsinghua campus network has developed rapidly.
In the past, Tsinghua network equipment can be called a "universal brand." Cisco, 3Com, Nortel Networks, Extreme Networks, Netgate, and other well-known manufacturers of routing and switching products built a complex campus network. As a scientific research network, Tsinghua Campus Network provides a rich environment for learning and research. However, with the continuous advancement of university informatization, people found that there are some problems in the construction of Tsinghua's campus network: due to the inconsistency of network equipment, it has made network management more difficult; there is a time difference between the introduction of new technologies and new products by various companies, and they are optimizing network configuration There are many obstacles; the Tsinghua campus network not only undertakes the teaching and scientific research tasks of this department, but also provides great public network services. The security system of the “Wanguo Brand†network equipment is also facing severe tests.
Promoting the unification of Tsinghua's backbone network architecture is an effective way to solve the problem, and with the popularization of the Gigabit technology of the campus network and the maturity of the 10G technology, the expansion of the Tsinghua campus network to 10G is also a good time. The adoption of Cisco's 10G network solution by Tsinghua University this time is the result of a combination of technology, brand, reliability, security and other factors. At the same time, the successful deployment of Cisco 10 Gigabit Networks in many well-known international universities also provided a good reference for Tsinghua University.
At the Stanford University on the other side of the ocean, the Cisco 10 Gigabit network architecture has been successfully deployed. Stanford chose the Cisco 10 Gigabit router as the core of the backbone network. At the same time, it adopted dual-route backup at key nodes to ensure that the network is always smooth, and introduced a full set of Cisco IP voice technology to reduce communication costs. The completed 10 Gigabit network has played a core supporting role in modern university education, and has accumulated rich experience in streaming media teaching and open experimental teaching.
Features of Tsinghua 10 Gigabit Network Architecture
Tsinghua University, which is close to the academic background of Stanford University, believes that the diversity of campus network user groups determines that the 10 Gigabit campus network system should be borrowed between large enterprise networks and carrier-class public service networks, and is an operational core network platform. . In view of this, the industry's first 200 Gigabit / second (GPPS) half-rack Internet configuration router, the Cisco 12410 router, has become the first choice for building core equipment for the Tsinghua 10 Gigabit campus network.
The Cisco 12410 router has 10-slot cabinets and switches, where the throughput of each line card slot reaches 20Gbps (10 Gbps full-duplex); supports 10Gbps Oc-192C / STM-64c and four-port OC-48c / STM-16c crossbar switch to support distributed packet forwarding, and continue to support all existing Cisco 12000 series line cards; the use of innovative virtual output queuing (VOQ) technology (this technology can prevent line head end blocking), Enhance the performance of the clock scheduler, with application-specific integrated circuits (ASICS) specifically for high-speed applications, so it can achieve carrier-class performance and reliability, provide guaranteed priority transmission of data packets, and guarantee a true 10Gbps line for fully loaded systems speed.
The built Tsinghua 10 Gigabit campus network supports the seamless expansion of systems and services through a distributed architecture, while maintaining the performance of current multi-service networks and reducing their costs and simplifying their complexity.
These characteristics play a key role in enriching the educational methods of modern universities. Because it can support a large number of real-time services (such as VoIP and VoD), it can achieve the diversity of video technology, which is the basis of teaching innovation. Multi-protocol label switching (MPLS), as a key component to realize business networking, requires stable broadband support, and at the same time integrates traffic engineering, virtual private (VPN) and connection services, which will prompt the campus network to realize more operational applications and support more. Revenue-generating business.
Multiple applications show 10G value
Today, at Tsinghua University, with the help of 10 Gigabit network, not only online course selection, online course scheduling, examination inquiry, online examination, etc. have become the basic means of daily teaching and school administration, but also have a solid foundation in the construction and application of electronic libraries basis. At present, the electronic abstracts index database of Tsinghua Electronic Library has covered almost all disciplines of the school. There are more than tens of thousands of full-text electronic journals, which is twice the number of paper journals, and can be used anywhere on the campus network. Not only can the library search millions of volumes of books and other multimedia materials, but the library has also established cooperation with many large-scale book and literature information centers in the world. In the future, more video materials will be stored and disseminated via the wide network. The richness of streaming media will enable future Tsinghua students to face a wider world.
Innovation creates a better future. With the help of Tsinghua 10 Gigabit Network, students' innovative thinking can be extended to the maximum extent. Today, many Tsinghua students use the ideal network environment to make a variety of attempts to network technology and applications: R & D of enterprise management systems, VoD on-demand, non-linear editing, monitoring video acquisition, 3D cluster design ... almost all the latest information imaginable The application can find the explorer in Tsinghua Park.
In addition, Tsinghua Gigabit Network also has a unique advantage in connecting to the next generation Internet. The first is the technological advancement, which is reflected in the support of IPv6, broadcast routing protocols, and quality of service control QoS. The second is openness and innovation.
