“ An Architecture for Providing End - to - End QoS - based Advanced Services in the Internet ”
The following paper is focussed on the CM Toolset distributed measurement toolkit and its use in AQUILA European IST project for scalable end-to-end QoS based networking. CM Toolset is integrated in AQUILA intra-domain QoS measurement architecture including QoS database and distributed measurement agents, traffic flow generation and active probing tools as well as router performance monitoring. QoS analysis for single and aggregated traffic flows as well as measurement based admission control strategies using CM Toolset are discussed. Intra-domain QoS monitoring scenarios including CM Toolset as measurement architecture for AQUILA DiffServ core network environment are overviewed. CM Toolset measurement concepts are compared with current measurement architectures and research. Perspectives for extension of CM Toolset measurement architecture for inter-domain QoS monitoring are outlined.
