Fairness Enhanced Dynamic Routing Protocol in Software-Defined Networking

Abstract

Software Defined Networking (SDN) with flexible control has a high potential and applicability in modern networks. SDN has outstanding advantages in actively and centrally controlling network functions such as dynamic-routing, load balancing, and preventing congestion for data flows to ensure the stability, fairness, and quality of the network system. For stability, response speed and fairness are required in modern networks. This paper proposes a new routing protocol called Fairness Enhanced Dynamic Routing Protocol (SDN-FERDP) to reduce the network congestion and optimize the load balancing of the network. The emulation result on Mininet shows that SDN-FERDP can effectively reduce network congestion and better balance the load of the network compared to the OSPF in the traditional network (simply refer to as OSPF) and Modified OSPF in the SDN network (refer to as SDN-OSPF).
