Finding most reliable paths for software defined networks

In this paper, we introduce a new approach that computes the shortest-reliable end-to-end paths for centrally controlled networks like software-defined networks (SDNs). The proposed method aims to find the correlation between the routing mechanism and reliability with the purpose of decreasing the required time of backup path installation through reducing the number of required rules at the moment of failure towards guarantee the fast restoration of the affected path, hence leading to the reduction of the overhead on SDN network controller and the probability of the loss of packets. We also investigate the correlation between the network topology and its reliability and demonstrate the benefits from this relation through experiments using well-known SDN network simulation tools.
