Abstract
This paper describes a flow-aware QoS model for implicit service differentiation in the Internet to maintain end user best effort interface while differentiating services within the core network. The edge router architecture and functionalities are described and algorithms are proposed for QoS provisioning without the need of explicit on line signaling. The feasibility of the approach is proved with reference to two different service classes (i.e. best effort and real time) and their implementation in a modular software environment on a PC-based test bed. The sensitivity of the system to the main design parameters and the effectiveness of the QoS algorithms in terms of bandwidth usage efficiency and congestion limitation are obtained by practical measurements.
