Maestro is proposed: an NFV orchestrator for wireless environments that is able to decide among several possible VNF compositions which are more suitable for each situation, and it is shown how fronthaul bandwidth consumption can be reduced threefold considering different V NF compositions against atomic VNF placement.
Improving IT Change Management Processes with Automated Risk Assessment
A solution for automating the risk assessment process, which combines historical data from previous changes and analyzes impact of changes over affected elements is presented, which is capable of raising the quality of changes, therefore reducing service disruption caused by changes.
