Enhanced Network Stability and Reliability using Software-Defined Technology

One of the most important qualities that a reliable network should have is the ability to withstand errors without being disrupted, as this is one of the most important aspects of the network. It is necessary for systems to have fault-tolerance solutions in order for such systems to have high availability and dependability. The proliferation of software-defined networking has led to the emergence of both new possibilities and new challenges for the development of novel fault-tolerance solutions, topologies, and standards. This has resulted in the emergence of both new possibilities and new challenges for the development of software-defined networking (SDN). In this research, we talk about the fault-tolerance that is offered by SDN as well as the assistance that OpenFlow offers for failure recovery and how it is related to the fault-tolerance that is supplied by SDN. During the process of failure recovery, the stages of detection and recovery that are used by carrier-grade networks are where the major focus of our attention is placed. In addition, we focus on the fault-tolerance challenges that are unique to SDNs and provide a complete account of the research that is presently being done on fault tolerance in SDNs. This research is being carried out in the United States. After that, discussing fault tolerance in SDN research organised according to the three unique levels of SDN. This follows the previous step (i.e., application,data and control). In conclusion, we will review the conversation by outlining some potential next steps for the development of fault-tolerant SDNs within the context of the research community.
