Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Please refer to figure 1 , the present invention provides a measurement system based on mimic defense and Sketch algorithm, comprising an input agent, a micro-execution unit, an output arbiter and a feedback controller; the input agent, a micro-execution unit, an output arbiter connected in sequence; the feedback controller is respectively connected to the micro-execution unit and the output arbiter.

[0027] In this embodiment, the micro-execution body set unit includes several mimetic micro-execution body sets and bucket structures; preferably, the data structure of the Sketch algorithm is divided into micro-execution bodies according to the principle of the same function and different principles. Multiple micro-executive bodies are further combined into a micro-executive body set, and the insertion algorithm, extraction algorithm, and query a...

Abstract

The invention relates to a measurement system based on mimic defense and Sketch algorithm, comprising an input agent, a micro-execution unit, an output arbiter and a feedback controller; the input agent, the micro-execution unit, and the output arbitrator connected; the feedback controller is respectively connected with the micro-executive unit and the output arbiter. While improving the robustness of network measurement, the present invention reduces the serial computing overhead of multi-execution bodies brought about by the mimicry structure of coarse-grained Sketch algorithm, increases the degree of heterogeneity while reducing the granularity of execution bodies, and greatly improves the Measure the efficiency of the system.

Description

technical field [0001] The invention relates to the fields of mimic defense and network measurement, and specifically relates to a measurement system based on mimic defense and Sketch algorithm and an abnormal traffic detection method. Background technique [0002] With the popularization and development of the Internet, the network environment has become increasingly complex and diverse, followed by the emergence of network attack methods, and the security situation in cyberspace is very severe. In order to avoid the huge loss caused by the failure of network defense, it is necessary to discover potential security threats in time. The network measurement technology represented by the Sketch algorithm can monitor the network in real time, collect traffic information, and accurately feed back the network status, and provide network administrators with real-time network information and potential abnormal traffic information, so it has attracted more and more attention. In add...
