Towards Failure Resiliency in 5G: Service Shifting

  title={Towards Failure Resiliency in 5G: Service Shifting},
  author={Francesco Malandrino and Carla-Fabiana Chiasserini and Giada Landi},
Many real-world services can be provided through multiple VNF graphs, corresponding, e.g., to high- and low-quality variants of the service itself. Based on this observation, we extend the concept of service scaling in network orchestration to service shifting, i.e., switching between the VNF graphs implementing the same service. Service shifting can serve multiple goals, from reducing operational costs to reacting to infrastructure problems. Furthermore, it enhances the flexibility of service…
