Description of the Flow-to-VC Mapping Control Module in DIANA ́s RSVP over ATM Architecture

This paper describes the Flow to VC mapping control module that is embedded in the RSVP over ATM implementation of the ACTS project DIANA. As part of an edge router at the ingress to the ATM network, this module provides signalling translation from RSVP to ATM, handles the admission of flows to ATM VCs and controls an IP over ATM queueing discipline. It is thus an example of a traffic descripto...

ELISA: European Linkage between Internet Integrated and Differentiated Services over ATM

Nowadays we are witnessing the growth of Internet at an unprecedented rate. However, the current Internet does not guarantee Quality of Service for user flows, which prevents the provision of good quality for multimedia streaming applications over long distance. This led to the development of the Integrated Services architecture and recently to the Differentiated Services architectures. On the ...

Design and Implementation of a Flexible, QoS-Aware IP/ATM Adaptation Module

The overlaying of IP-based networks onto ATM subnetworks is a network configuration pattern found increasingly often. While IP networks traditionally only offer plain "best-effort" service they are now evolving to offer more sophisticated services. Nevertheless, the exact mechanisms for providing QoS in IP networks are not yet settled and essentially non-existing in today’s production-level net...

Advanced Mechanisms for Available Rate Usage in ATM and Differentiated Services Networks

The Available Bit Rate (ABR) service category was defined for ATM networks in order to provide a minimal guaranteed rate while letting a user exploit additional unused capacity from other service categories. In this paper experiences with an implementation of a driver enabling ABR support and the steps needed to integrate it in an end system are described. Furthermore, the deployment of ABR in ...
