The network users at the Bonn site consider order administration, e-mail and calendar access to be the most important uses of the network. The order administration system uses HTTP to transfer data. The actual usage pattern is shown in Figure 3-10.

Using the data on network use and the user input, the network administrator designed the class hierarchy shown in Figure 3-11 and assigned the priorities and percentages of bandwidth shown in Table 3-2.
