Embodiment Construction

[0021] The invention provides a realistic generation method of multi-fractal Web logs based on steady-state process, such as figure 1 shown, including the following steps:

[0022] Step 1: Generate attributes for each user and form a collection of users U ={ u 1 , u 2 , ……, u n}, n represents the number of users, un Indicates the first n users;

[0023] Step 2: Generate properties of each web file and form a collection of web files I ={ i 1 , i 2 , ……, i m}, m Indicates the number of web files, u m Indicates the first m a web file;

[0024] Step 3: Associating users and web files to form the original request sequence R ={ r 1 , r 2 , ……, r q}, q Indicates the number of web logs in the original request sequence, r q Indicates the first q Web logs;

[0025] Step 4: Use the alpha steady-state process to fit the user arrival model, and calculate the user arrival time interval ∆ T , as the passive OFF time of the improved ON / OFF model, the arrival ti...

Abstract

The invention relates to a realistic generation method of a multi-fractal Web log on the basis of a steady-state process. The method comprises steps as follows: a user set and a Web file set are generated, users and Web files are associated to form original request sequences R, a user arrival model is fitted by adopting an alpha steady state, the arrival time interval delta T between two times of arrival of the users is calculated and taken as passive OFF time of an improved ON / OFF model, the original request sequences R are changed into a user set composed of multiple user request sequences, one user request sequence Ru is formed for each user, each user u is traversed, binomial fractal is performed with the adoption of a binomial b model, the access time interval delta t between two times of file transmission is calculated and taken as active OFF time of the improved ON / OFF model, and the user request sequences Ru are combined again to form new sequences Ru'. By means of the method, the self-similarity and the multi-fractal can be combined, so that the real Web log can be accurately simulated.

Description

technical field [0001] The invention relates to the technical field of simulation generation of large data sets, in particular to a realistic generation method of a multi-fractal Web log based on a steady-state process, which can be effectively applied to Web Simulation Generation of Log Large-Scale Datasets. Background technique [0002] exist Web In server performance testing, analysis Web Log features are of great significance for server performance evaluation and decision-making. However Web The log contains user privacy information, and organizations such as enterprises and governments are rarely willing to disclose the log for researchers to use; the existing public Web The log data is old, and its characteristics do not conform to the characteristics of the current big data era. As the scale of data increases, it is difficult to generate representative but general large-scale data sets, and it is difficult for a single traditional simulation model to represent mu...
