Abstract：Real-time application is an increasing application, but there are many application traffic should be transferred by Internet. The performance of real time applications such as video and voice streams relies on packet delay jitter. Large delay jitter causes buffer overflow and the user encounters interrupts. The delay jitter is mainly due to the perturbation of background traffic in the router. The jitter analysis has been made are all based on poisson process and recent study has proved its inaccurate. In this focus, a theoretical analysis of packet jitter of CBR stream was provided and different influence on CBR stream by self-similar and poisson back-ground traffic was validated by simulation result.
