71Network Resource Management for Various Services Using Flowvisor in SDN Architecture Maryam Tabaiyan Ms tabaiyan@ec iut ac ir Date of Submission 2015 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor MasoudReza Hashemi mhashemi@cc iut ac irAbstractGrowing needs of large organizations and end users have made the traditional structure of networksinsufficient to address the needs of the users As a result the network industry has been forced to reconsiderthe traditional structure Software Defined Networks SDN is a new architecture for networks that offerssolutions to the needs of the new generation of networks The virtualization feature in SDN enables thenetwork operators to share the same physical medium among a number of different virtual networks Thisresults in better and simpler control of these networks In SDN networks the data plane and the control planeare separated It provides the ability to perform centralized control over the entire network In this thesis byusing tools such as SDN OpenFlow switches controllers and Flowvisor a new solution to achieve the goal ofsharing a common physical network for two different services with different resources requirements isprovided The major characteristic of this solution is ease of the network management to isolate two servicessuch as video and data which have quite different quality of service requirements In this thesis it is shownthat in addition to the data transmission network on same transmission medium VOIP and TV traffic can berouted simultaneously without mutual interference In this implementation application of Flowvisor to reachthe desired goal is introduced and it is shown that the virtual networks can be managed to share resourceswhile achieving traffic separation with the aim of providing quality of service appropriate to the type ofnetwork traffic It is concluded that this aim can be achieved in SDN architecture using tools like Flowvisormuch easier than doing so on the older methods Keywords Software Defined Network SDN Virtualization OpenFlow Flowvisor
