Abstract

In this paper we present PLF (Promotion of Long Flows). PLF tries to promote web traffic using the Token Bucket Model in a DiffServ framework. This algorithm preserves the high priority for short flows but tries to allocate some long flows in the high priority class level, in order to improve some performance parameters of the long ones. Finally, we present PLFwp (Promotion of Long Flows with Penalization) in order to detect (and cancel) the effect of these extremely long flows over the global performance. We analyze the results for packet loss and web transmission latency.
