   \subsection{Perspective}

   \begin{sitem}
      \item Network users: services that their applications need
      e.g., guarantee that each message it sends will be delivered
      without error within a certain amount of time

      \bigskip\bigskip
      \item Network designers: cost-effective design
      e.g., that network resources are efficiently utilized and fairly
      allocated to different users

      \bigskip\bigskip
      \item Network providers: system that is easy to administer and 
      manage e.g., that faults can be easily isolated and it is easy 
      to account for usage
