subject: Ruijie Campus Card Network Solutions - Campus Card - Education Industry - China 4d Electric Key [print this page] In the global digital wave under the influence, of the University Digital Campus Construction broad attention, universities across the country by the Chinese Education and Research Network (CERNET) to promote the building of strong, moving from each side of the Digital Campus contact with the subject. In recent years, with the promotion and use of smart cards, to various management functions and community service, certification integrated campus, "Card" is open to all Universities and Colleges. Campus "One Card" to the smart card as the information carriers, combining micro- Electronic Technology, single chip technology, computer network technology and database technology, and many other high-tech, it has the electronic identification and electronic purse functions, replacing the daily needs of school teachers in the traditional work permit, student card, book card and with cash-related transactions canteen Fanka (vouchers), medical certificate, the machine certificate, tickets, etc., to teach, learn, test, evaluation, housing and comprehensive digital and network, and truly "one card in hand, anywhere on campus" .
Network platform in the Campus Card The underlying system is the cornerstone of campus card, Ruijie company has 7 years service Education Information Experience in building, through in-depth analysis and study, designed with high stability and high security features of the card network platform to support the campus card operation.
One, needs analysis Underlying network infrastructure is the cornerstone of successful implementation of campus card. Can not choose the right network infrastructure will lead to the following questions: system performance degradation, the high failure rate, a large number of security problems and cumbersome maintenance and management issues, which is unacceptable for users. In addition, if there is no proper network design, network infrastructure will be difficult to meet the rapid development of the campus card network expansion and upgrade capability. "Campus Card" system involves the use of funds, settlement and with the banking system, networking, and related to the general staff and students of teaching, learning and living normal, so the stability and security is a very important design aspects.
Security requirements Although Campus Network Already has a considerable network of security measures to ensure the "Campus Card" system to prevent illegal users through the campus network intrusion, should be independent and build "Campus Card" network so that the "Campus Card" relatively closed network, not with external system, especially the Internet directly connected, that is, building "Campus Card" special network, campus network and the "Campus Card" special network of logical isolation.
If for business needs, must be in the campus network and the "Campus Card" communication between private network, you can use IPSec tunnel mode, on the campus network and the "Campus Card" special network between exchange of data encryption and the prevention of "Campus Card" malicious data being stolen, and the campus network and the "Campus Card" special network for critical Server Strict access control policies to prevent unauthorized users access to these important servers, to protect the "park card" special network data safe. ,
Stability of the demand School campus card carries a lot of business development, network stability and reliability becomes more important?? Network easily disconnect the history does not matter a few hours have passed. On the other hand, application-rich, the network environment has become very bad, security attacks rising exponentially, the knowledge required is weakening, a variety of attack tools on the network can be picked up at random. It also Network equipment The proliferation of network attacks or virus in the context of stability and reliability challenges. Construction of campus card network, therefore first need to have a stable network equipment itself, the design of the network architecture should be followed to ensure multi-link equipment redundancy, and finally the link between the multi-campus on the link not only to the traditional redundant backup, also need to access the link through the form of different equipment.

Network topology Card network backbone is a data flow of the arteries, the flow of information is also entrusted with the overall scheduling task. Therefore we believe that a star network topology is the best choice for network topology is as follows:
Shown: the center of the network switches back rate should be chosen large enough to satisfy the data flow of the multi-switch, the center of the network will not be network congestion points, while also ensuring network redundancy , flexibility is the rapid convergence failure. Therefore, we have chosen in each campus two RG-7606 switches form the network center, 7606 provides a 6 slot backplane rate of up to 1.6T, the exchange capacity up to 864G.
Aggregation layer switches use RG-5750 switches can be Gigabit and Gigabit uplinks to core switches. Gigabit fiber optic or twisted pair connections through the access layer switch
Switch for a large number of access points, we use RG-S21 Series switch products, providing access to 100M, while the link with the core switch via Gigabit links.
System reliability
Network as the cornerstone of campus card system, safe and reliable operation of the very high demands to the network can provide the stability of 7 * 24 hour service, so the choice of the core equipment reliability is first.
