Problems solved by technology
[0003] The network management system mainly uses SNMP, RMON, Netflow, Sflow and other protocols to collect the traffic conditions of each interface from routers and switches, so as to provide users with the traffic conditions of each device and link in the network, but it cannot analyze network behavior and find the cause of performance degradation
[0004] Network performance measurement and analysis system mainly measures the connectivity, delay, delay change, bottleneck bandwidth, loss rate, etc. behavior and find the point of failure or bottleneck link
[0005] The network security system mainly finds the intrusion behavior in the network through the in-depth analysis of the group, and sends out an alarm message, but cannot find the degradation of the network performance or find the source of the attack traffic

The present invention provides a network behavior analysis system, which collects application, protocol, connection, flow, content, performance and other information in the network from links, routers and switches in the network through one or more data collection systems, and Preprocess the collected information; the communication system transmits the preprocessed data of each data collection system to the data analysis system; the data analysis system performs real-time, historical and selective network behavior analysis and analysis on the collected data. Future network behavior prediction; the display system displays the network behavior analysis results to users. The present invention is an internal network management, performance analysis, and network security detection system, which can be used for capacity planning, troubleshooting, problem prevention, service level management, application layer analysis, application monitoring based on application identification, and network monitoring based on data sources , Discover unknown applications, locate network attacks, etc.
Description
technical field [0001] The invention belongs to the technical fields of network management, network performance analysis and network security, and in particular relates to a network behavior analysis system. technical background [0002] Existing technologies on network management, network performance analysis and network security all have certain limitations. [0003] The network management system mainly uses SNMP, RMON, Netflow, Sflow and other protocols to collect the traffic conditions of each interface from routers and switches, so as to provide users with the traffic conditions of each device and link in the network, but it cannot analyze network behavior and find the cause of performance degradation. [0004] Network performance measurement and analysis system mainly measures the connectivity, delay, delay change, bottleneck bandwidth, loss rate, etc. Behavior and find the point of failure or bottleneck link. [0005] The network security system mainly finds the in...
