Mapping an internet assured service on the GFR ATM service

Abstract

As Internet is rapidly growing and receiving traffic from multimedia applications which 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. Since ATM is widely deployed in Internet backbones, traffic management for Internet traffic over ATM is becoming an important issue. In this paper we present a simulation analysis of an Assured service mapped on the ATM GFR service category. We study the problem of guarantying individual target rates to an aggregated IP stream. Aggregated streams are mapped with a MCR according to the QoS requested. © 2000 Springer-Verlag Berlin Heidelberg.
