Design and analysis of hybrid software defined network system for stability enhancement

Software-defined networks (SDNs) facilitate more efficient routing when traffic flows using centralized network view. On the other hand, traditional distributed routing still has the advantage of better scalability, robustness, and swift reaction to events such as failure. Therefore significant potential benefits to adopt a hybrid operation where both distributed and centralized routing mechanisms co-exist. This hybrid operation however imposes a new challenge to network stability since a poor and inconsistent design can lead to repeated route switching when the two control mechanisms take turns to adjust the routes. In this paper, we discuss the ways of solving the stability problem. To develop the stable networking environment three tire routing architecture is proposed. The router stability is enhanced and speed of data transfer is high in this proposed system. The router will analyze the network traffic that occurs during the data transfer and redirect to the other router. The algorithms used in this proposed systems are Support vector machine algorithm and Multilayer perception algorithm. The stability of a hybrid-software defined network involves the consistency between the centralized routing performed by the centralized controller and the distributed routing performed by the individual local routers. If these two control units are not consistent with each other, the routing decision may be overturned repeatedly as they take turns to modify the routes.
