A Path Supervision Framework A Key for Service Monitoring in Infrastructure as a Service (IaaS) Platforms

Current service platforms, e.g. Cloud solutions, do not adequately address the requirements exposed from certain kind of services like real-time services. Infrastructure as a Service Platform (IaaS) supporting these service requirements, such as quality of service of the resources provided, heavily depend on measurements in order to be able to verify that the quality of service as contracted in a service level agreement (SLA) towards the IaaS platform is kept on service layer. This paper presents the concept of a path supervision framework in the context of virtualized service infrastructures, such as IaaS platforms, spanning over use cases for service monitoring and measurement methodology. Moreover, the overall monitoring framework supporting the guaranteed execution of real-time services in such an execution environment is presented.
