Dr.COM Chongqing University Campus Network Authentication and Billing Solution

Due to its huge coverage and complicated network environment, university networks have always been representative cases of network construction. How to achieve reasonable authentication and charging in a large-scale campus network will directly reflect the wisdom of the network authentication and charging system provider!

background:

Chongqing University is located in Chongqing, a major industrial and commercial town in the southwest of the country and an economic center in the upper reaches of the Yangtze River. It is one of the first batch of key universities in Southwest China to be built by the "211 Project" and "985 Project". Chongqing University currently has four campuses A, B, C, and Huxi, with a school building area of ​​more than 1.68 million square meters, and 26 colleges. There are more than 58,000 full-time students and more than 5,800 in-service teachers and staff.

Recently, in response to the current expansion of the teaching scale, Chongqing University has joined hands with the Beijing City Hotspot Company, which has been working on the network of university authentication and billing for 10 years, to access the network authentication and billing system for the school. As a key university with a large scale and leading education. In the process of setting up the network, how to achieve accurate and accurate authentication and billing; how to take into account the needs of various campuses and buildings to connect to the network; how to make charging and management convenient and clear have become serious problems in front of urban hotspots.

solution:

After analyzing the campus environment of Chongqing University, the hot spots of the city are treated according to its characteristics, and the authentication and charging are divided into three steps: campus network access, background management, and foreground authentication.

1. Access: Considering the large coverage and complex structure of the campus network of Chongqing University, urban hotspots adopt a distributed access method for the campus backbone network. The topology diagram is as follows:

Three Dr.COM2133 authentication and accounting gateways are distributed to access the campus network server port, and each device performs authentication and accounting for the designated area, so that the accounting systems of different campuses do not interfere with each other, and can take into account the functions of the campus and the building Separate billing.

2. Background management: After completing the main network access, the city hotspot takes into account that the major network service center as the unified manager of the school network, and having a convenient background management system is the basic guarantee for maintaining the campus network. Therefore, based on the Dr.COM standard interface city hot spots, Chongqing University Network Center Operations Management System was developed. Operators can use this system to complete the query and modification of user account information, login records, operation records and other information, and activate new student registration accounts.

The concise but perfect background operating system provides a very simple and clear operation platform for the maintenance and management of the campus network by the Chongqing University Network Center.

3. User self-service platform: After completing the first two steps, the city hotspot has built a front-end user self-service platform for Chongqing University.

In the user login interface, in addition to login, registered users can also perform password modification and client download functions according to their own user nature (such as office users, student users, family area users, etc.). Unregistered users can register through this interface and wait for the background administrator to activate the user before they can use it.

After users successfully log in to the self-service platform, different users can perform basic user information query, login query, payment query, bill query, password change, start and stop, tariff change, address change and other services according to their own needs.

Since then, the access to the authentication and billing system of the campus network of Chongqing University has been basically completed. The completion of these three major steps provides a solid foundation for campus network billing management. But these alone cannot make Chongqing University campus network authentication and billing a perfect system. Only after considering the details of the campus network of Chongqing University does it truly reflect the professionalism of urban hotspots.

Consider in detail:

1. The Dr.COM system is connected to the campus card

For the convenience of management, teachers and students and employees in the school all use the one-card system for payment. To this end, the city hotspot has connected the independently developed Dr.COM authentication and billing system with the campus card system. Users can directly transfer to the campus network account, check the balance of the campus network account, and open and shut down the campus network account through the card storage machine. This not only facilitates teachers and students to perform network payment and other operations, but also greatly saves the school's cost in charge management. Only a set of fee system can be used to manage all expenses of teachers and students living on campus.

2. Client domain name resolution

In order to achieve load balancing of the billing gateway, all student user clients use the same login domain name: gate.cqu.edu.cn. According to the different original IP address of the user login, the DNS server resolves the user to different Dr.COM billing gateway IP Login address.

to sum up:
