Recent work has demonstrated that network traffic has self-similar properties. These properties make short-term control of traffic very difficult. Heavy tailed distributions of burst sizes contribute to traffic self-similarity. In this paper, the effects of heavy-tailed file transfer traffic on queueing behavior are demonstrated using a simulated traffic source based on empirical Unix file size data. A method of application-level traffic shaping, whereby selected large traffic bursts are shaped, is developed. This shaping method is shown to dramatically decrease ATM cell loss at a bottleneck queue. At the expense of a few large file transfers being increased in time duration, many smaller file transfers are decreased in time duration and cell loss is decreased for all file transfers.
