324 Chapter 10: Managing Network Performance with Queuing and Compression
Scenarios
The following case studies and questions are designed to draw together the content of the
chapter and exercise your understanding of the concepts. There is not necessarily a right answer
to each scenario. The thought process and practice in manipulating the related concepts is the
goal of this section.
Figure 10-9 provides the topology for all scenarios in this chapter.
