Supporting QoS Monitoring in Virtual Organisations

摘要

There are methods proposed for managing various aspects of quality of service (QoS) in service oriented computing environments, but existing effort tends to adopt a provider-centric perspective, aiming largely at optimising and guaranteeing QoS for service delivery. In this paper, we consider QoS monitoring from a service user's perspective. We describe an approach in which monitoring requirements are expressed as queries in a simple language and are processed against continuously arriving QoS data streams.
