dc.description.abstract Autonomous management and orchestration (MANO) of virtualized resources and services, especially in large-scale NFV environments, is a big challenge owing to the stringent delay and performance requirements expected of a variety of network services. The quality of decision (QoD) of a MANO system depends on the quality and timeliness of the information that it receives from the underlying monitoring system. The data generated by monitoring systems is a significant contributor to the network and processing load of MANO systems, impacting thus their performance. This raises a unique challenge: how to jointly optimize the QoD of MANO systems while at the same minimizing their monitoring loads at runtime? This is the main focus of this paper. In this context we propose a novel automated NFV orchestration solution called z-TORCH (zero Touch Orchestration) that jointly optimizes the orchestration and monitoring processes by exploiting machine learning techniques. The objective is to enhance the QoD of MANO systems achieving a near-optimal placement of VNFs at minimum monitoring costs.
