Dynamic metric OSPF-based routing protocol for Software Defined Networks - 2019

Dynamic metric OSPF-based routing protocol for Software Defined Networks

Research Area:  Software Defined Networks

Abstract:

Routing protocols are needed in networking to find the optimal path to reach the destination. However, networks are changing both their use finality and their technology. Paradigms like Software Defined Networks (SDNs) introduce the possibility and the necessity to improve the routing protocols. In this paper, a modification of the Open Shortest Path First (OSPF) routing protocol is proposed in order to allow the protocol to change the metric calculation dynamically according to the network requirements. Experiments, which compare our proposal against the OSPF protocol, are performed in five different scenarios. In these scenarios, the performance of the multimedia traffic has been increased 33% in terms of bandwidth utilization, 80% of loss rate reduction and delay reduction on VoIP communications.
