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

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 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 multicontroller 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 multicontroller 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.

Automated summary

Financial Technology has transformed financial services by enhancing the efficiency and effectiveness of operations and processes. However, the abundance of big data generated across different locations can strain the network infrastructure. To address this challenge, the proposed approach leverages software-defined networks (SDN) to provide scalability and resilience. In case of controller failure, the approach includes an adaptive recovery mechanism in a multicontroller SDN setup using support vector machine-based classification approach. The results demonstrate its favorable performance based on the considered evaluation parameters.
