Abstract

In UNLP’s network, like in most of thepresent networks, a great percentage of thetraffic network demand is that of HTTPprotocol. At the moment it is around 60%. Tobe more precise, we would have to claim thatmost of the traffic is transported by TCP port80. Although port 80 TCP is used by default byprotocol HTTP, any other application can useit, taking advantage of the fact that usually thisport is not filtered and that it is even assigned agreater priority over the others. This workproposes a way to classify traffic at the top levelof the application. The objective consists ofapplying effective techniques of QoS, thatdistinguish HTTP from other protocols as wellas different uses which the users generally give,like being navigation, streaming anddownloading
