Abstract：Analysis on Optical Burst Switching(OBS)network performance based on the Poisson model would not be exactly. In this paper, the distribution of data burst length is researched, and it is simulated that the self-similarity of data burst traffic assembled by time-based mechanism, moreover, the performance of LAUC and LAUC-VF are shown in the simulations. Simulation and theoretical results show that the assembly mechanism based on time threshold can decrease the traffic’s self-similarity, on the other hand, the influence of self-similarity on LAUC is small, but much greater on LAUC-VF whose burst drop probability will be decreased by 3 percent than Poisson stream.
