Tsinghua University Library
The Tsinghua University Library was founded in 1912, and the gallop consists of two parts of the integrated thing. The total area of library has a total construction area of 2,800 square meters and sets a 7th selection of 2,000 seats. Tsinghua University Library has ordered nearly 50,000 books in China and foreign books in recent years. By the end of 2003, the Tibetan books in the general museum have reached 2.74 million, forming a variety of types of various types of humanities, social sciences and management scientific literature, forming a natural science and engineering technology, and a variety of carriers. system. The library implements an open service and is open daily. WWW, OPAC (Collection Directory Retrieval) 24-hour external service. In 2003, there were 1.41 million readers, and the total amount of Chinese and foreign books was 11.4 million.
"If you say that only half of the students bring laptops to the library in the first two years, the library's self-study room is almost a computer, and the density requirements for network access can be imagined." Talking about wireless network systems At the time of construction, the deputy director of the Tsinghua University Library, the deputy director of Lu Airi, described the pressure facing the library, which is the reason why the Tsinghua University Library will use the wireless network as a key point of information construction.
Under the joint efforts of all parties, the Tsinghua University Library has successfully built a high-speed wireless network that fully covers the reader, librarians, and office area, helping libraries to successfully respond to new challenges brought about by the Internet. , Lay a solid foundation for the future to create a digital library in the future.
"Improvives" brought by laptop
Tsinghua University library collection exceeds 3.75 million (pieces), now, Tsinghua University Library has developed into a traditional library of traditional libraries into a modern library of research type, digital, civilized, and has provided powerful for school teaching and research activities. Supporting and effective protection, made important contributions in the school's talent training and scientific research, and became an important support platform for building a world-class university in Tsinghua University.
Entering the Tsinghua University Library, you can see readers from time to see the information, browse the network, and teachers and students are enjoying the convenience of wireless networks. Jiang Yirong, deputy director, introduced that with the proportion of digital book resources in the library collection, the network has become an important infrastructure of the library. With advanced wireless networks, readers can quickly query campus information and find academic literature resources, so keep the wireless network smooth, is an important goal of library IT construction.
In fact, Tsinghua University Library has deployed wireless network in most readers in 2003. At that time, the main problem facing the library was that the number of port ports was limited, and it was difficult to meet the gradually growing network access needs of teachers and students. The joining of the wireless network is well compensated for the problem of lack of wired network ports and is deployed, and has played a very important role in a period of time.
However, with the rapid spread of laptops in recent years, the original wireless network of Tsinghua University Library begins to face more "troubles". Chen Wu, deputy director of Tsinghua University Library System, recalled that the previous wireless network has only deployed more than a dozen wireless AP, and the system takes a FATAP architecture. When the readers that need to be acces gradually increase, the entire wireless network system is overwhelmed, not only the network speed is lowered, but the user access is difficult, but cannot achieve authentication and centralized management, unable to control unsecurity access and virus problems, and even lead to the whole Network operation is not stable. "After the number of last users, some problems have been highlighted, affecting the normal operation of library services."
In response to this situation, Tsinghua University Library launched the transformation of Wi-Fi in 2009, through the bidding, eventually selected the wired wireless integrated solution provided by H3C to carry out system deployment, officially officially official The smooth switch of the new system is achieved.
Wireless network set up "new" bridge
After the transformation of Tsinghua University Library Wireless Network has a "leap" than before. The entire wireless network consists of two mutually hot wireless controllers ACs and 100 wireless access points AP. The network signal not only covers the reader area, but also covers the librarians and office spaces. The access point of the entire wireless network increases, whether it is a network access speed or the stability of the network operation, the use of the teachers and students has greatly improved, and further improved the Tsinghua University Library. Service capability. "Now the wireless network signal has covered every corner in the museum, and even the staff of our staff can be done with the wireless network."
However, although the scale is much larger than before, the management difficulty of wireless network is reduced. Unlike the initial system architecture, the current Tsinghua University Library Wi-Fi is a FITAP structure. The IT department can use the centralized management function of the H3C wired wireless integrated solution to centrally manage through the wireless network controller. In this way, the management difficulty is reduced, and the workload is reduced, and the wireless network will become more controllable. Libraries can develop and deploy more detailed management strategies for some specific situations, such as automatically turn off wireless networks after closing, and have achieved many additional effects in security, green, etc.
Since the H3C wireless network solution can be closely integrated with various campus network business, Tsinghua University Library Wireless Network achieved access certification, students, students, students, students, and teachers who can use their school / work number. Network access to the campus network. This avoids the abuse of resources, and reduces the risk of invasion, viruses, etc., which has more guarantees for the stability of the network.
It is worth mentioning that the Tsinghua University Library Wireless Network System, which is completed, implements the double stack support for IPv6 / IPv4, which is also a point in Tsinghua University Library. Jiang Yirong, deputy director said that IPv6 technology is currently in colleges and universities. The Tsinghua Campus Network has long supported IPv6 and IPv4's dual stack applications, and currently in the library field, IPv6 address access many education network resources There is still cost advantage, Tsinghua University Library is trying to migrate some resources to IPv6. Therefore, when selecting a wireless network solution, the support capabilities of IPv6 have become one of the key factors considered. All H3C wireless networks employed by this wireless network can support IPv6 / IPv4 double stack applications, which is well solved. The readers can access IPv6 resources without obstructive access from which port access is hindered, and laid a "bridge" between the reader and the collection resources.
The transformed wireless network system is very stable. Chen Wu, deputy director of Tsinghua University Library System, said that since the double master, mutual hot standby, the stability and safety of the wireless network are greatly enhanced. From January this year, the Tsinghua University Library Wireless Network has been stable and normal, and this is fully explained.
Looking forward to the future development, Tsinghua University Library will continue to vigorously promote the construction of digital library in the network environment, provide advanced digital information utilization environments for teachers and students, according to reader demand and library development, actively explore and try resource discovery systems, New technologies such as mobile Internet and mobile libraries, constantly improve service level and service results. Wi-Fi will continue to help readers more common, faster, gain information resources, play more important roles in digital library process. Read more
