Method and device for statistic of layering flow

Abstract

The invention discloses a hierarchical flow statistic method and device which belongs to the data communication field. The method includes steps: processing flow statistic to current layer in flow statistic layer divided in advance, and recording statistic data in current layer; when flow statistic satisfied with next layer of current layer starting strategy, processing flow statistic to next layer of current layer, and recording statistic data of next layer of current layer. The device includes: a first statistic module, a first trigger module and a second statistic module. The method provided by the invention divides flow statistic layer according with standard from coarse to fine, sets flow statistic strategy to flow statistic layer respectively, processes flow statistic layer-by-layeraccording with set flow statistic strategy, realizes processing flow statistic according with need, and preferable ensures balance between equipment cost and flow precise statistic.

Description

Method and device for hierarchical traffic statistics technical field The present invention relates to the field of data communication, in particular to a method and device for hierarchical traffic statistics. Background technique As the network is more and more integrated into people's work and life, the network capacity is getting larger and the connection complexity is getting higher and higher, based on the needs of business and security, operators and network management designers are paying more and more attention to the equipment For detailed traffic conditions, the interface-based traffic information statistics technology for data communication products came into being. In addition, in order to reasonably adjust and optimize the existing network and optimize the performance of the network, detailed network traffic information must also be used as the basis. Especially in recent years, the outbreak of viruses and network security incidents has also put forward highe...

Problems solved by technology

After researching the existing technology, the inventor found that: On the one hand, the traffic statistics in the prior art can only be performed manually. For example, if you want to perform traffic statistics on a sub-interface, you need to manually input the enable command to start. If you want to stop Traffic statistics on sub-interfaces also need to be manually input to disable the command to stop, and the labor cost is high.

If you want to capture the sudden abnormal network traffic of sub-interfaces, you need to count the traffic of all sub-interfaces of the main interface to avoid omissions. At this time, you need a large amount of storage devices such as memory or chip registers, so as to greatly improve equipment cost

On the other hand, with the continuous development of the network, traffic statistics are no longer limited to fixed physical interfaces, nor are they limited to several types of packets. Statistics for a large number of interfaces and statistical categories also require a large amount of memory or chip registers, etc. Storage equipment, which also makes the cost of the equipment significantly increased
