This slideshow presents the fundamentals of a groundbreaking concept called "Orchestrated Assurance", developed as a ETSI NFV PoC #36. For service providers, Orchestrated Assurance dramatically changes the way to deliver, operate and troubleshoot new services. Orchestrated Assurance is based around a model-driven service orchestrator that uses software-based active test agents in NFV to enable automated, agile and assured service deliveries. The PoC was carried out by Netrounds, with participation from Cisco, Intel and Telco Systems, with support for Orange.
