Embodiment Construction

[0016] The present invention will be described in detail below with reference to the drawings.

[0017] The bypass flow detection model based on the shunt orientation of the present invention is aimed at network flow detection and content identification, and designs a structure model for a high-performance parallel detection processing system. The model includes a shunt, a flow directional distributor, and a flow Detectors, anomaly alarms, and anomaly aggregators implement multi-detector parallel detection by classifying and pre-processing traffic and divert orienting them. If anomalies are found, they will send out alarm messages and process abnormal traffic or data packets together. The detailed working principle is as follows (see figure 1 .):

[0018] 1) The splitter is responsible for copying out the exact same flow to be checked from the flow to be checked;

[0019] 2) The flow directional distributor divides the flow into a series of types according to the external character...

Abstract

The invention provides a bypass type flow detection model based on split-flow direction, mainly comprising a flow splitter, a flow directional distributor, flow detectors, an abnormality alarm and an abnormality collector. On the basis of flow classifying and splitting directional treatment, the invention realizes multi-detector parallel detection, sends out alarm information when finding abnormalities, and intensively treats abnormal flows or data packets. Because the detection part of the model has a tree-shaped structure, the model can realize larger-scale parallel treatment through carrying out cascading iteration after the treatment of a flow director. The invention can be widely applied to various network flow detection systems and effectively realizes and improves the properties of parallel high-speed detection on the flows, ideal linear expansion and updating and the like.

Description

Technical field [0001] The present invention relates to the field of network monitoring, in particular to a network flow detection, in particular a bypass flow detection model based on shunt orientation based on in-depth detection and content identification technology. Background technique [0002] Network traffic detection is the basis of Internet security monitoring and network traffic control. Over the years, the industry has proposed various algorithms and solutions. These technologies are mainly aimed at the network traffic itself, and determine its type by identifying the external characteristics and composition characteristics of the traffic itself. , And there is relatively little research on the workflow and architecture technology of the network traffic detection system. At present, various popular fireproof walls, intrusion detection systems, security gateways and other equipment mainly work through direct detection and analysis of network traffic, and then make the pr...
