Simulation-based Demonstration

In [8], Park, Kim, and Crovella shows that in a ``realistic'' client/server network environment, the transfer of files or messages whose size is drawn from a heavy­tailed distribution, can directly determine the degree of traffic self­similarity at the link level, which is shown in Figure 2.
