Joint resource management and action scheduling for carrier-grade NFV

Software upgrades, reconfiguration, and deployment of new services happen so frequently in the carrier-grade VNF-based networks that operators need automated orchestration and change management systems. The current approaches deal independently with each service and concentrate mainly on resource allocation or optimization of the change execution processes. We propose a new Joint Resource Allocation and Scheduling (JRAS) approach, where the orchestrator manages changes, addressing the diverse requirements and dependencies of all services together. These features result in significant gain achieved by JRAS compared to other approaches, as shown by the performed numerical analysis.
