Abstract: This paper presents a generating technology of self-similar test traffic. By comparing typical self-similar traffic models, it analyzes the multifractal wavelet model, brings out an algorithm to generate self-similar test traffic, and applies it on the network testing system based on IXP2400 programming multi-core processor. With the network testing system, it presents the test results of the self-similar test traffic according to the value of Hurst (0.5, 1.0) and proves the correctness and validity of the paper’s technology.

Key words: self-similar, multifractal wavelet, multi-core, test traffic
