IMPROVING TRAFFIC CONTROL USING SOFTWARE DEFINED NETWORKING FOR INTER-DOMAIN ROUTING

Abstract

Software Defined Networking (SDN) is becoming a de facto paradigm in data networks. While smaller campuses and enterprises are not yet widely deploying SDN, larger campuses and data centers are already utilizing the advantages of SDN, primarily taking advantage of easier network management, better resource utilization, better load and traffic balance on network devices and routes. Denial of service has been another concern for the last decades, and in the current internet it has not been fully addressed. The present paper analyzes and tests possible applications of Software Defined Internet Exchange Point (SDX) for inter-domain routing. The results from simulated implementation showed that SDX as a platform offers a greater flexibility and allows for better traffic engineering than conventional techniques. In addition, it gives a possibility to fight denial of service attacks.
