In order to illustrate the different validation algorithms that are examined in this chapter, I will use a simple example that commonly arises in the enterprise environment. Assume that this is an enterprise that wants to support application-level SLAs for its customers. These SLAs are specified in terms of the application response time that occurs when a specific client accesses an application. The high-level policies that will be specified by a user will map each usage scenario, a client accessing an application on a server, to a service class.
