Simulation Of Jellyfish Topology Link Failure Handling Using Floyd Warshall and Johnson Algorithm in Software Defined Network Architecture

There are several types of network topologies in the data center, one of which is the Jellyfish Topology. The main problem in Jellyfish is a link failure. Link failure causing connectivity between devices to go down. To solve that problem, necessary to design and simulate a backup path for the net- works. The emerging technology in networks is called Software Defined Networks (SDN). Using SDN, the administrator can easily program the network via a controller. SDN can solve the problem by configuring the controller in order to create a backup path on-the-fly. In order to find the optimum backup path when a link failure occurs in Jellyfish topology, floyd-warshall and johnson algorithm used in this paper. Simulations are carried out with parameters convergence time, packet loss, and throughput. Based on our experiments, Floyd Warshall outperforms the Johnson algorithm in all parameters.
