Summary: 
The effectiveness of traffic shaping for VBR traffic is analyzed. Evaluation results prove that traffic shaping can improve link efficiency for most forms of bursty VBR traffic and that link efficiency gains of more than 250% can be expected without the shaping delay imposing any significant QOS deterioration. Traffic shaping increases the link efficiency to about 80% for traffic with short burst repetition periods. The traffic shaping techniques and analytical results described herein can be employed in the traffic management of future B-ISDN/ATM networks.
