Abstract [en]

Functions Virtualisation (NFV) and Software Driven Networks (SDN) aggregate resources across multiple domains. This puts requirements on understanding the overall alarm status across these domains and dependencies between them. Current practice of low-quality alarm documentation and confusion around fundamental concepts like alarm states, alarm-types and the underlying protocols like syslog and SNMP traps makes it hard to create one unified alarm interface as part of the SDN API.If alarm interfaces for the various components were expressed in a more formal manner including dependencies and propagation between the alarms the NFV/SDN interface could automatically present an integrated alarm API as well as a synthesized alarm state across the virtualized functions.We present a novel approach to alarm interfaces by providing a formal alarm model together with a domain-specific language that allows us to specify both the alarm models and the constraints placed on the alarm models in a consistent manner. This means that we can verify the consistency of an alarm interfaces and automatically generate interfaces, multi-domain correlation and aggregated states.
