Enhancement of Network Throughput in SDN Using Shortest Path Routing Algorithms

Software-Defined Network has bought a massive change in traditional networks, which has enabled dynamic adaption and configuration. In data centers, SDN helps to create a virtual network where the controller forms centralized control for the entire network, but the network topology used in data centers needs to be more scalable and flexible to avoid network congestion. Thus, in this project, the fat-tree network topology is created to find the shortest paths between the source node and the destination node. Open flow protocol is used for the transmission of messages. The experiments are performed for a specific time interval to evaluate the TCP and UDP network bandwidth. Also, a comparison is made between the two parameters i.e., hop count and delay based on the shortest path. To simulate the entire network Mininet emulator tool is used to design the network topology, and the RYU controller is used for packet routing. This research shows that the network throughput can be improved when the packets transmitted from source to destination have low hop count and delay(weight).
