Lenovo Campus Network Scheme

Lenovo Program Center in Tsinghua cernet implementation of the database cluster system is running on the Linux platform.

With the rapid development of campus network, more and more schools in the student dormitory building a local area network, college students have become a real broadband users. Therefore, a broadband billing system is urgently needed to improve and improve our service while strengthening the management. Considering the existence of a large number of campus rooms, student dormitories, the existence of fixed IP, the face of users and the billing needs of the unit, Tsinghua "Security based on user authentication billing system" is a user's account management, IP management, billing management as one integrated management system. Users can be "one-time registration, and then through the account/password authentication online." At the same time, the system "to account/password authentication identity, according to its then used IP address computing network traffic" to complete the billing. The billing system based on user authentication is put into operation in Tsinghua University campus network 2001.1. Now on this basis to further improve, in order to promote the entire Cernet university campus network.

With Intel's active assistance, the Lenovo Application Program Center, based on fully understanding the current Cernet application, carries out testing and partial optimization on the hardware platform of the Tsinghua Information Network Engineering Research Center for the billing system software. The main solution to the current from the campus network to the Internet billing issues, users from the Web page landing or client software landing through the gateway server to the Internet, the system needs to verify the legality of the user and the flow of the statistical billing. Through the testing of the POC (Proof of Concept) of the software system in Wan Quan server, the whole system is debugged and optimized, the system can run stably and efficiently, and has very good performance index.

Tsinghua University through the Lenovo Application Center for its billing system solution to the POC test, the use of Lenovo NS10000 as its background database system, on-line operation is good, Lenovo to excellent technical services and products to win the trust of customers.

Due to the expansion of the scale and the failure of the network Center, we hope to find a solution to realize the redundancy of the Network center of its north gate, and realize the load balance and parallel processing between the two places. Lenovo Applications Center in countless trials and experiments in the process, based on the existing NS10000 system to find the ability to achieve the above features of the solution, and for the choice of the project pressure and fault testing.
