Due to the inability to accurately record the traffic generated by visiting international sites on the campus network, schools have caused unnecessary losses; and some schools have simply closed the access addresses of international sites to avoid losses, so that the campus network has no real connection. Into the Internet. In this way, some advanced foreign scientific and technological materials that are urgently needed by students are not available. Other schools have adopted the network billing system as a proxy server for the above reasons. However, with the rapid growth of network bandwidth and the number of users, traditional proxy server billing methods cannot complete accurate billing on high-speed broadband networks, and expensive hardware costs continue to increase. This requires network service providers to provide different levels of service and formulate different charging standards for users with different needs.

According to CerNet's current charging policy and the above practical problems, how to charge becomes a very important issue, and the use of a reasonable charging system is the guarantee of the normal operation of the campus network. Against this background, Founder Technology ’s campus network billing solution came into being. It is designed to monitor and manage internal network users ’access to the Internet based on summarizing the practical experience of network billing in many colleges and universities. The complete set of billing and user management solutions provides comprehensive billing management support for the campus network environment, and fundamentally solves the charging problem caused by accessing the website after accessing CerNet.

At present, there are many ways to implement network billing, mainly including router-based, proxy server-based and firewall-based billing systems. However, due to the different forms of billing products and the different technical methods adopted, it has caused technical defects in other products themselves. The Founder Technology network billing system uses a transparent gateway-based billing method, adopts transparent gateway technology and incorporates billing and control functions, and is designed for broadband IP billing. This design has the following four outstanding characteristics:

1. MAC address and IP address binding

Due to the advanced nature of the system's logic functions, the billing gateway binds the MAC address to the IP address through user registration to prevent IP address or account misappropriation, and accurately records the flow information used by the user to the user account. Broadband billing applies to all broadband environments. It can implement static binding when a user opens an account or dynamic binding when a user logs in.

2. Accurate flow recording and control

The transparent gateway directly operates on the IP layer, so only the partial information of the traffic generated by the IP registered by the user is recorded, and its comprehensiveness and accuracy are beyond doubt. All resources of the software system are used for packet filtering and forwarding, and forward network multi-layer data at line speed, so the impact on the network speed is almost zero, and the transparent function is truly realized.

3. Perfect billing plan

Provide a complete billing plan, support domestic (free range), foreign (charged range), classified traffic records, support logout of user logout, forced logout of the administrator, and system timing three ways of traffic logging and support for traffic Record of source address and destination address.

4. Powerful manageability

Support classification management of ordinary users, users who owe money, and punish users; support rich real-time management functions, you can view the dynamic registration information of users and hosts, you can forcibly cancel the registration of a certain host or user, and you can manually update the host information of the system And user information; at the same time, it has good scalability and can achieve seamless link with other billing software (such as mail, proxy, dial-up billing software).

Founder Technology ’s campus network billing system has strong independence and is not affected by the specific technology and equipment of the network backbone layer and access layer. It can be flexibly deployed in the network system and set the billing gateway at the exit or some In this network segment that requires billing, it does not depend on any third-party network hardware and software. Due to the rich IP address of CerNet network, the actual IP of CerNet is generally used after school access, and the IP allocation of the Internet is very limited, only need to achieve access to Internet resources through IP address conversion.
