摘要：Now-a-days a huge increase of mobile traffic needs and increasing cloud data centers demands, the network managers requires some new approaches to handle the situations. The Software Defined Networks (SDN) has raised as a promising solution providing more effective, programmable and granular configurations in order to isolate all the dynamic traffic requirements and spiky changes in the physical topological status of the networks from the network management. In this paper, we propose a novel SDN Controller which classifies the network traffic types according tothe heterogeneous Quality of Service requirements that the network data is separated into the Constant Bit Rate (CBR) based real-time traffic and File Transfer Protocol (FTP) based non-real time traffic. Some pivotal activity stream parameters, for example, parcel conveyance proportion; steering overhead and postponement are additionally considered in this characterization. A novel convention header is additionally created by the proposed SDN controller keeping in mind the end goal to spread the fundamental data through the L2/L3 switches in the Data Plane. This header is made out of the Parameter, Rule, Controller Action subfields. The proposed SDN controller chooses the best system organization technique, i.e. turning into an impromptu or being concentrated, utilizing the activity sorts, system parameters furthermore, the header data. An itemized execution assessment is given which shows the effectiveness of the proposed SDN controller while choosing important arrangement considering the heterogeneous movement sorts and in addition the expanded number of clients in the topology. Apart from the present system, we additionally include the security enhancements by means of crypto methodologies such as RSA and SHA, with this we can achieve high security and data rates without any attack possibilities over Software Defined Network.
