Embodiment Construction

[0022] The following describes in detail each embodiment of the service flow detection method and system of the present invention.

[0023] First, each embodiment of the service flow detection method is described.

[0024] See figure 1 , Is a schematic flow diagram of the service flow detection method of the present invention, including the steps:

[0025] Step S101: Collect flow data of each device.

[0026] Data collection is the foundation of all analysis services and the entrance to the data flow of the entire system. Data collection can be roughly divided into four methods: Netflow, sFlow, SPAN, and SNMP / RMON. These methods are device-related. That is, some devices can only support one or several collection methods. Each collection method has its inherent advantages and limitations.

[0027] In one of the embodiments, a composite collection scheme with self-adaptive flow and mirrored traffic is adopted to collect both mirrored data and flow data directly. The mirrored data is ...

Abstract

The invention discloses a service flow detection method and system. The method comprises the following steps of collecting the flow data of each piece of equipment; carrying out normalization processing on each piece of flow data to obtain an equipment data flow containing space information, time information and technical index information; on the basis of the space information, polymerizing the equipment data flow to obtain a service flow tree; according to the relationship between sub service data flow and the equipment data flow in the service flow tree as well as the equipment data flow, determining the sub service data flow; comparing the service data flow, the equipment data flow and a preset service behavior rule to obtain the abnormal state of the equipment data flow and the sub service data flow; according to the abnormal state of the equipment data flow, the abnormal state of the sub service data flow, the service flow tree, the abnormal weight of the preset equipment data flow and the abnormal weight of the preset sub service data flow, obtaining a main service health degree index; according to the main service health degree index, determining whether the main service data flow is abnormal or not. By adopting the scheme, the detection accuracy is improved.

Description

Technical field [0001] The present invention relates to the field of network communication technology, in particular to a method and system for detecting business flow. Background technique [0002] With the improvement of the level of power automation and the development of communication technology and network technology, the power system is increasingly dependent on the power information network to ensure its safe, reliable and efficient operation. The safety of the information network is directly related to the safety of the power system, so it is guaranteed Power system information security is particularly important. [0003] With the in-depth development of integrated intelligent operation system research and development and application, the interaction between various applications based on OSB bus is growing rapidly, and security problems are gradually becoming prominent. Traditional power secondary system security protection faces huge new challenges. Different from traditi...
