Whole network flow analysis method of computer network

Abstract

The invention provides a whole network flow analysis method of a computer network. Real-time network flow data are collected from a network element management system of a flow monitoring device (flow probe), by adoption of the method, a monitoring function of real-time flow, flow topology, business flow, abnormal flow and other flow is realized, a flow statistic analysis function according to unit, business type, topological structure and other dimensions is realized, and a function of generating an alarm event when the flow exceeds a regulated threshold or when abnormal flow is detected is realized, therefore the flow monitoring of the computer network is accomplished; and the flow of the computer network is limited and controlled by regulating global and local flow control strategies and releasing the global and local flow control strategies to the network element management system of the flow monitoring device for implementation, therefore regular, efficient and orderly operation of the computer network is achieved.

Description

technical field [0001] The present invention relates to the technical field of network monitoring, and more specifically, to a method for analyzing the flow of the entire computer network. Background technique [0002] At present, with the development of network technology, the expansion of network scale, and the deepening of customer management work, it is necessary to accurately, comprehensively and automatically grasp the use of IP network services by user units at all levels in the entire network, and implement traffic monitoring on the entire network and control; capable of centralized traffic management with rights and domains; capable of customizing and dividing IP network user groups; capable of automatic identification of various types of business traffic on IP networks; capable of comprehensive statistical analysis of IP network traffic from multiple angles ability. Manage the bandwidth of important egress links; ensure the bandwidth needs of key users and service...

Problems solved by technology

[0004] In the prior art, the network traffic analysis method based on SNMP, because the data granularity is too low, so can not accurately carry out the statistics of the micro traffic; the network traffic analysis method based on the real-time packet capture technology is not suitable for collecting at the backbone network switch port The amount of data is too large, and the effect is not good; the network traffic analysis method based on network flow technology cannot collect complete user business traffic
