Incorporating smart software-defined networks to enhance resilience and survivability in the cloud : survey of current challenges and future research scopes

Abstract

With increased dependence on grids and the cloud, resilience and survivability become pre-requisites of backbone network infrastructure. Due to the unprecedented migration of data centers to both public and private cloud services; the need of an environment that provides agility combined with security and scalability becomes mandatory. The changing network scenario requires a standardized separation of data and control planes that will allow transparency and increase network resilience as metrics to improve security. Software-defined networks are being considered by many vendors to provide the ultimate solution to meet the increasing demands and serve the elastic growth of cloud services while providing sufficient flow monitoring, fault detection, and network management properties in highly-complex backbone infrastructure networks.
