Abstract

The implementation of successful Assured
Forwarding (AF) services according to the DiffServ
framework remains a challenging problem today,
despite the numerous proposals for AF PHB
mechanisms and AF-based service implementations. In this work, we propose two modules, the TCP-Window
Aware Marker (TWAM) and the Dynamic WRED
(DWRED) mechanism for implementing the DiffServ
AF PHB. We provide analytical models and an
experimental evaluation in order to demonstrate how
they succeed in enhancing the quality, increasing
fairness, improving the performance and easing the
deployment of a production- level AF-based service.
