The inflexibility and rigidity of the current networking systems in light of the growing number of computing devices that connected to the Internet has led to the need of a new generation of computer networks. In this context, software-defined network has recently emerged as one of the most recognisable solutions to facilitate the network management and decrease the complexity through detaching the control layer from network appliances. Since, each new technology accompanied with new issues and concerns, one of the main challenges that facing the SDNs is the fault tolerance and resilience. Although there are a numerous of studies that have discussed this issue, the after failure repair scenario is remained unclear and have not addressed well yet. For this reason, we specify this paper as a step forward to address the issue of routing changes, which is important for utilising the optimal paths after failure repair. We produced a new network model as well as a compatible framework with SDN architecture to fulfil the routing changes activity. The consequence is estimated based on an analytical model and finally, a case study example is provided in order to conceptualise the concept.
