Abstract

Monitoring of Service Level Objectives (SLOs)
determines an essential part of Service Level Agreement (SLA)
management, since customers are to be reimbursed, if a provider
fails to fulfil them. By automating this process, a timely detection
of a violation is possible. The compliance approach must be
flexible to adapt to potential changes, must be scalable with
respect to the amount of data, and has to support multi-domain
environments. This paper determines a Hosted Streaming
Services scenario and defines relevant SLOs. Key requirements
are derived, the respective architecture is designed, and the
approach is implemented prototypically based on a generic
auditing framework. Further-more, a new scheme is proposed
that considers the degree and duration of SLO violations in
calculating reimbursements.
