Figure 3-10 Actual Network Use for Bonn Site

The network users at the Bonn site consider order administration, email 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.
