Application Models and Performance Issues
In Chapter 2 we provided an understanding of the issues and techniques involved in carrying bit streams over wireless channels. The resources required to carry a bit stream depend on the characteristics of the stream (e.g., the average rate, peak rate, and rate variability), and the performance required by the application generating the bit stream (e.g., an interactive voice call requires end-to-end delay bounds, but can tolerate some data loss). In this chapter we will discuss the major types of applications that telecommunication networks are used for, and the performance issues related to these applications, particularly when wireless networks are involved.
