Resumen
As Internet is rapidly growing and receiving traffic from multimedia applications that are sensitive to available
bandwidth and delay experienced in the network, there is a strong need for quality of service (QoS) support. The
Integrated and Differentiated Service models are two approaches for adding QoS to Internet. The Assured Service is an
end-to-end service based on the Differentiated Service architecture. In this paper, we study and compare the
performance of three profiler mechanisms to provide the guaranties of an Internet Assured Service. Two of them, TSW
and Leaky Bucket are the most commonly used, and the third is a new Counter Based profiler, which is proposed in this
paper. The study is done by simulation employing TCP RENO sources.
