Service Level AgreementMonitoring for Resilience in Computer Networks

Today’s communication networks are migrating from resource based networks to service based network. These services could include, for example, financial, trading and other corporate services. Failing of such services would have significant impact, therefore it is important to ensure the resilience of a service as attributed in Service Level Agreements. In this paper we propose design of a test suite for stakeholders to investigate resilience and security requirements that have been defined in a Service Level Agreement. Also, the service providers can use this design to check compliance before delivering service and thus increase their performance. This paper will also stimulate the discussion of need of categorizing resilience parameters in existing SLAs and integration of SLA with policy based control for better management.
