Design And Implement Of Data Analysis And Summary In Network Flow Menegement System

Now, network operators face a big challenge in traffic analysis, security and billing of IP network. The system based on Net Flow protocol can help operators to collect and analyze network flow easily, it can help administrator know the distribution of network traffic and find out the malicious attack.Based on the practice of China SINOPAC management network system, the document describes the system design and implement of Network Flow management based Network Flow protocol. It mainly carries on the following aspects.1. Introduce related technologies of IP Network Flow Analysis. And it analyzes Network Flow protocol in detail.2. Analyze the function requirements of business needs from user's view.3. Come out the system design solution, including the architecture design and the function design. It also describes the problems found and gives out the solution of these problems.4. Describe the realization of data analysis and summary subsystem. Especially database design, data store and summary program design.
