Adaptive Recovery Mechanism for SDN Controllers in Edge-Cloud supported FinTech Applications

Ren, Xiaodong and Aujla, Gagangeet Singh and Jindal, Anish and Batth, Ranbir Singh and Zhang, Peiying (2021) 'Adaptive Recovery Mechanism for SDN Controllers in Edge-Cloud supported FinTech Applications.', IEEE Internet of Things Journal .


Financial Technology have revolutionized the delivery and usage of the autonomous operations and processes to improve the financial services. However, the massive amount of data (often called as big data) generated seamlessly across different geographic locations can end end up as a bottleneck for the underlying network infrastructure. To mitigate this challenge, software-defined network (SDN) has been leveraged in the proposed approach to provide scalability and resilience in multi-controller environment. However, in case if one of these controllers fail or cannot work as per desired requirements, then either the network load of that controller has to be migrated to another suitable controller or it has to be divided or balanced among other available controllers. For this purpose, the proposed approach provides an adaptive recovery mechanism in a multi-controller SDN setup using support vector machine-based classification approach. The proposed work defines a recovery pool based on the three vital parameters, reliability, energy, and latency. A utility matrix is then computed based on these parameters, on the basis of which the recovery controllers are selected. The results obtained prove that it is able to perform well in terms of considered evaluation parameters.
