The advancement of Computer Networks revolutionized the communication technology and paves a better and efficient way for sharing data. Traditional network device, design and deployment were remarkable, but in this era, it is not sufficient. A software defined networking is an emerging technology that is best suited and seems to be satisfied and further development is on the way to meet up the requirements such as high availability, programmability, and cost efficiency of the increased networking devices, and that is what people also waiting for. Because of its flexibility and availability, SDN is under deployment in a carrier grade network. High availability requires faster recovery of failed links. Hence, several methods were proposed and implemented by research scholars. One of the basic link failure recoveries is providing an alternate path for a source to reach its destination. In this paper a rerouting i.e. Providing a dynamic, alternate path to alleviate link failure is implemented in mininet version 2.2.2 which is installed on an Ubuntu 18.04 Bionic host. SDN usually comprises devices with a separated data plane and control plane and a special device called controller act as a brain. In this experiment, Pox controller is used, and the experimental topology is viewed via miniedit-a python program which acts as a GUI for creating topology and the interrupts less flow of ping is also shown. For the improved mechanisms of failure recovery, this implementation serves as the base.
Keywords- software defined networks, mininet, recovery of link failure.
