Distributed Campus Network Billing System

With the campus network applications increasingly more complex and expanding the size of the network, the network's management has put forward higher requirements. On the one hand, campus network users on the network increasing network performance requirements; on the other hand, the campus network security threats (such as DDoS, worms, malicious code, etc.) are more and more. Network management is a significant element of the operation of campus networks, and one of the network accounting is an important field of network management. Based on the account strategy which made by network management apartment, according to the user on the use of network resources by charging fees for the network to share the cost of running and maintaining the campus network construction and maintenance. Accounting Management as one of the five network management domain features is an important domain. The research and improvement of the campus network accounting technology and management strategy plays an important role in which the campus network to improve operating efficiency and safety conditions, and to protect all types of network applications to carry out the smooth.The distributed accounting management system can not only billing the network usage for a person or an organization, but also log and audit the network access in detail. So the accounting management can be used for performance management, configure management and security management. New system gathers the network flow by the distributed way, a distributed network accounting system which solved the inconveniences brought by adopting concentrated flow gathering, gathers network flow at each gathering point. At the same time, it uses concentrated monitoring, which controls and manages the running situations of flow gathering and analyzing other parts in real-time way, and makes it more manageable, which effectively resolves the choke point by the intensive way and reduces the errors and mistakes of accounting to make it more accurate.This paper is about the distributed accounting problem of campus network, as the question carries on the thorough analysis completely which can be solved by many kinds of method through the research of network accounting system .According to the character of campus network, accounting system adding the functions of user management and service management, it can expediently run users and service management. By using directory server, the system achieves centralized user management and uniform users ID attestation.
