With the deepening of library network construction and increasingly rich applications, library network construction is also facing more and more new topics. How to achieve reasonable authorization of users outside the library to access resources in the library? How to achieve the security of the network while maintaining the openness of the library network has always puzzled the network builders of university libraries. 1. High security Product details

Analysis of the needs of university library network construction:
1. Safety requirements
Libraries are the core department of universities, and cyber security incidents have occurred frequently in recent years. How to ensure the security of the data in the library, the identity verification, authorized access and post-supervision of the network access users in the library have become issues that have to be considered when constructing the campus network of colleges and universities.
2. Management needs
How to use limited manpower and material resources to efficiently manage the network of college libraries, how to manage numerous equipment and users in an integrated manner, and how to quickly locate in the event of a network failure have become the key points to be considered when constructing the network of college libraries.
3. Performance requirements
There are a large number of library network applications, such as FTP file transfer and other large amounts of data access, resulting in huge network traffic. How to carry out network transmission at high speed puts high demands on network equipment of the whole network.
4. High intelligence considerations
With the application of a large number of network services in the library, how to differentiate the network application and make the library network more intelligent has become an inevitable requirement in the network construction of college libraries.
5. Consideration of access methods
At present, more and more teachers and students are using laptop computers, which makes the wired port of the library more and more tense, which brings great difficulties for teachers and students to access materials on the Internet. However, simply adding a wired port is only a temporary solution, and cannot fundamentally solve the problem, so the application of wireless networks has become the best way to solve the problem.
6. Demand for outside visits
The library's rich collection of books and newspapers, as well as a large number of network databases are the most abundant information libraries on the library's network. But at present, most library resources can only be accessed in the library, and the urgent demand of many readers is not limited by the location of the library, and it is easy to freely obtain library information resources. Therefore, through reasonable authorization to make it possible to access the resources in the library without the library becomes the goal of the library network construction.
Features of university library solutions:
Based on the above problems and needs in the construction of library networks, Ruijie Networks, with its rich experience in library network construction, has proposed a high-security, high-performance, and easy-to-manage college library network solution.
Ruijie Networks ---- Network Topology of University Library:
1. Safety certification to the desktop.
The combination of six-element automatic binding, static binding, and dynamic binding can ensure the unique identity of users when they connect to the network, and avoid IP conflicts.
2. Control network viruses.
Unifiedly implement security policies for access layer switches to easily and effectively control network viruses and keep the network smooth.
3. Defend against cyber attacks.
Combined with the network attack detection system, it can resist the increasing number of internal network attacks, and automatically make corresponding control actions to users to ensure network security.
Second, easy to manage
1. Unified management of equipment across the entire network.
Network-wide topology discovery and unified management of events, performance, and logs can facilitate the unified management of equipment across the entire network, and the strategy is better than a thousand miles away.
2. Access period management.
Through the one-time setting of daily, weekend and holiday, it is easy to flexibly manage the time period when users can use the network, and improve the intensity of user management.
3. Automatically upgrade the client.
Through a unified one-time configuration, the client of all users is automatically upgraded, which greatly simplifies the burden of managers and users and makes Internet access easier.
3. High performance
The entire network adopts the design concepts of 10 Gigabit core, Gigabit trunk, and 100 Gigabit to the desktop. High-throughput, wire-speed forwarding core routers and Layer 3 switches, the redundancy of key devices, and hot-swap technologies that support boards, all ensure the efficient operation of the network.
Leading SPOH structure design, hardware-based synchronous data exchange technology. According to the different port dependence of different data behaviors, different processing methods are adopted to maximize the processing capacity of the whole machine.
For the data behavior of individual ports such as ACL and QOS, by adding an independent FFP module (fast filter processor) to each port of the ASIC chip for hardware processing, each port can perform hardware processing in synchronization.
L2 / L3 / Multicast etc. involve data processing behaviors between different ports. All the ports are processed uniformly through the unified hardware look-up entry of the online card ASIC chip to provide line-speed forwarding of data between different ports.
Four, multiple access methods
For access to library resources, Ruijie Network Library Solution provides corresponding access methods:
1. Wired access in the hall
2. Wireless access for users in the library
3. VPN access for users outside the library
Five, end-to-end QOS
From the access layer switch to the core equipment, it fully covers the port rate limit, application flow classification and identification, and critical service flow bandwidth guarantee and other multi-layer switching quality assurance.
Based on switch time, physical port, MAC address, IP address, TCP / UDP port number, application flow classification recognition and bandwidth speed limit mechanism, the end-to-end QOS guarantee of the entire network of the university is completed.
