Method for carrying out data flow analysis and management on network appliance

Abstract

The invention discloses a method for carrying out data flow analysis management on network equipment. The method overcomes the technical limitations of the current network management system to network flow and flow direction analyzing function, can not only carry out statistics to network bandwidth utilization rate with high efficiency, but also carry out analysis and statistics to the flow and the flow direction of businesses of different types. Therefore, after being adopted, the method of the invention can not only provide a solving proposal for IP charging, but also provide a network security detection tool for enterprises and network administrators; in addition, a plurality of specific convergence manners are allocated in a router or an exchanger terminal, thus greatly reducing flow coarseness sent to the administration server of a network management center and ensuring that the processing capability of a management system can adapt to the increase of network scale in the future.

Description

Technical field: [0001] The invention relates to the field of computer data communication, and mainly relates to a method for analyzing and managing data flow on network equipment. Background technique: [0002] In recent years, China's Internet business has developed rapidly, especially the rapid growth of multimedia services such as video and voice. The IP network has also changed from a single data network to a multi-service integrated digital network, resulting in complex and diverse network data. sex. Under this trend, in order to ensure a stable, safe and efficient network operation environment, people hope to manage the network efficiently and reasonably. For network administrators, they are eager to monitor users' network application behavior in real time and effectively plan and deploy network resources; for network operators, they hope to be able to timely and accurately monitor the network and various services it carries. and flow analysis, timely grasp the load...

Problems solved by technology

However, the current network traffic analysis and management systems have significant technical limitations: for using the SNMP protocol to manage and monitor the network traffic of key links and network connection points in and out of the network, the data packet information it collects is very rough. , there are both customer service information at the network layer, frame header information at the data link layer, and the payload field of the data load. The most critical thing is that the different service flows in the network layer cannot be distinguished by using the SNMP protocol. The flow direction of data packets cannot be analyzed; for the analysis and management of traffic using the RMON protocol, although the technical limitations of using the SNMP protocol can be partially resolved, such as different service flows at the network layer can be distinguished, but because the RMON protocol must target each data The collection and analysis of frames consumes a lot of CPU resources, so it cannot be implemented in network devices. You can only purchase and install built-in or external RMON probes, and the network data collected by using the RMON protocol is analyzed every time. The amount of data is large and scattered, and the protocol itself lacks a built-in data aggregation mechanism. In addition, there will be no BGP AS number and next nexthop information in the data packet, so for large-scale network traffic Management and analytical capabilities are not available
