RETRACTED ARTICLE: Design of an effectual node balancing cluster with partitioner algorithm using Markov decision process

Abstract

In recent times, the foremost challenging task in implementing software defined networking is to choose appropriate locations for controllers to reduce latency amongst switches and controllers in wide area networks. Based on the existing investigations, most of the studies concentrate on reduction of packet propagation latency, however propagation latency is an essential contributor of overall latency amongst switches and associated controllers. In this research work, investigation is carried out on most significant contributor of latency, such as end-to-end latency and queuing based latency of controllers. So as to reduce end-to-end delay, the network partitioning idea is anticipated and an efficient node balancing cluster with partitioner algorithm using Markov decision process (NB-PAMDP) is modeled for network partitioning. NB-PAMDP can ensure that every partition is competent to reduce maximum amount of end-to-end delay amongst switches and controllers. In order to diminish queuing delay of controllers, an appropriate multiple controller placement are then designed for sub networks. Extensive simulation was carried out in NS-3 simulator under a network topology from Internet topology. Results demonstrate that the anticipated model can resourcefully diminish maximum latency or delay amongst switches and corresponding controllers.
