Abstract

This chapter gives an overview of the Internet activities in the COST-257 project. Section 4.2 presents a short overview of the analysis of Internet traffic. Section 4.3 describes the different aspects of Quality of Service (QoS) in the context of traffic streams. The section starts by defining traffic aggregates such as stream based or elastic traffic. First the traffic aggregates themselves are investigated, followed by the consequences of their integration for network and resource dimensioning. The impact of different pricing schemes for the QoS of different traffic classes is studied in Section 4.4, followed by a detailed investigation of the differentiated services (DiffServ) concept of the IETF in Section 4.5. Switching and routing with all the important aspects such as DWDM, MPLS and QoS routing is addressed in Section 4.6. The Chapter ends with an overview of the COST-257 contribution to the integration of IP and ATM networks and some comments on server dimensioning.
