Network background generation system and network background generation method based on multi-node traffic playback

Abstract

The invention provides a network background generation method based on multi-node traffic playback. A multi-node network traffic playback work is completed by mutually calling a traffic file pre-processing module, a playback network generation module and a multi-node traffic playback module together; the traffic file pre-processing module provides input information for the playback network generation module; the traffic file pre-processing module divides a traffic file, generates a data stream file, and performs statistical analysis on the data stream file so as to form statistical information; the statistical information of the traffic file pre-processing module is used for outputting configuration files, required for construction of playback network topology, by means of playback networkmapping; a playback network is generated according to the configuration files, and the analyzed and processed data stream files are distributed to all nodes; under the premise that a user only uploads the traffic files and a small number of parameters, virtual network topology is generated by analyzing the traffic files and utilizing the statistical information; background traffic generation is completed by using a way of multi-node traffic playback.

Description

technical field [0001] The invention relates to the field of scheme selection, in particular to a network background generation system and method based on multi-node flow playback. Background technique [0002] In the process of network scene construction, traffic playback is a common method, which is to use the experimental platform to generate a network and nodes with the ability to interact between hosts, and inject the pre-captured data packet files into the nodes after cleaning, and follow the data packet files. Replay them sequentially to realize the technology of simulating traffic interaction in specific network scenarios. At present, traffic playback methods are mainly divided into the following two categories according to the playback method: one is to generate specific traffic based on a mathematical model and play it back between hosts or between multiple network cards in the host; the other is to capture real traffic and How to replay. For the model-based traf...

AI Technical Summary

Problems solved by technology

For the model-based traffic generation and playback scheme, only the basic characteristics of traffic, such as packet size, duration, etc., are simply considered, and a single type of network traffic is generated, which cannot satisfy the self-similarity and long-term correlation characteristics of traffic

In addition, for the existing playback method based on real traffic, although the self-similarity and long-term correlation characteristics of the traffic can be guaranteed, the playback scenarios are mostly between multiple network cards of a single host or between two hosts, which cannot Meet the scale of the range environment background flow simulation
