Design of Fuzzy-Based Traffic Provisioning in Software Defined Network

This Software defined networks helps to realize extraordinary services that can be easily embedded in network operations of switch. It provokes the decomposition of the control and data planes. The control plane is more extensible, as it is unproblematic to change or introduce any new functionality into the network. It is studied that any new integration can be easily added up with a very low line of code (LOC). The work proposes a fuzzy based approach for traffic provisioning in SDN. Fu zzy Logic Control System (FLCS) is a controller co mp rising of two fuzzy systems - Label Switched Path setup System (LsS) and Traffic Splitting System (TSS). The co mputation of dynamic status of Load and Delay is utilized by LsS to arrange the paths in preference order. The attained Link Capacity and Utilizat ion Rate are emp loying by TSS for maintain ing congestion free path. Created three different topologies and performed ping reachability test and executed iperf testing tool for performance analysis on Mininet framework.The impact of this is to facilitate better decision making for splitting the traffic for different capable paths. Simulat ion setup is deployed using OpenFlow Switches and Controllers to study their performance. The packet delivery rat io remained above 98% , showing rare chances of congestion and delay was below than 2.6 seconds with TTL in range of 60-80 milliseconds.
