摘要: Network function virtualization (NFV) and software-defined networking (SDN) are two recent paradigms that strive to increase manageability, scalability, programmability dynamism. The former decouples network functions hosting devices, while the latter data control planes. However, as more operators adopt these new paradigms, there is a growing need address multi-failure conditions, particularly those arising from large-scale disaster events. Hence this study proposes enhanced “risk-aware” virtual mapping traffic routing schemes improve reliability of user services well reduce deployment costs.
