Abstract
Network Function Virtualization (NFV) has changed the face of telecom industry by replacing the hardware network services with software-based Virtual Network Functions (VNFs) that offer greater scalability and flexibility of services. On the other hand, virtualization problems with dependability are caused by infrastructure failure, software bugs and resource contention. An NFV based IP Multimedia Subsystem (IMS) is tested in an experiment and experience is gained in this paper to understand the robustness of the NFV-IMS via controlled fault injection. A quantitative assessment of service availability, latency, throughput and recovery time is complemented by a qualitative assessment of fault detection, isolation and recovery behavior. The results show how effective virtualization management techniques are at not only maintaining the continuity of service, but at also determining where the limits of resilience lie when operating in adverse conditions. The study provides concrete recommendations for robust telecom infrastructure design for NFV.
