Service Degradation in FAN

In this chapter, it is shown that the admission control routine in Flow-Aware Networks may lead to severe fair rate degradation, which negatively impacts the performance of streaming applications. The chapter starts by showing the problem and its effects on transmission performance in detail. Next, several ways of solving it are presented. Since admitting too many flows is the problem, all the solutions presented in the chapter revolve around limiting the number of flows that a router can admit in a certain amount of time. These solutions improve QoS assurance capabilities of FAN and enhance its scalability.
