Abstract

An application layer based QoS mechanism is proposed so that QoS to IP Traffic is provided solely based on the individual requirements of the applications. The mechanism of communication between application layer and IP layer to provide information of the QoS requests, the marking model of IP packets, and the evaluation of end to end performance in terms of standard QoS parameters are addressed. We have proposed 5 categories of Internet traffic based on their QoS requirements. We also have carefully studied the accommodation of popular TCP based applications like FTP and have minimized its interaction with other UDP applications. Finally, mapping is presented for proposed Internet traffic categories in a way that each of them achieves its QoS requirements.
