The fast-developing Internet brings convenience to the network and rapildly expands the network scale. It puts for-ward higher requirements for the measurement and analysis of network behavior characteristics. The Internet planning design and management work cannot be separated from the support of network behavior characteristics analysis. To meet the monito-ring requirements of network behavior, this paper mainly studies and designs the net work monitoring process of network behavior characteristics analysis. Based on the analysis of the status quo of network behavior characteristics analysis, based on the requirements of network behavior characteristics analysis, the network is completed. The design of the monitoring system and the construction of the IP network behavior evaluation index system are organically combined with the network monitoring technology and data analysis technology. The functional architecture and implementation path of the system are introduced in detail, which has good scalability and enables real-time monitoring of network behavior. The requirements are effectively met.
