Network resource provisioning in cloud data center across manifold SDN controllers

Software Defined Networking (SDN) is an emerging technology to abstract the physical hardware which provides the large amount of data storage in the Software Defined Data Center (SDDC). In our proposed work, the Virtual Tenant Network (VTN) improves the scalability of network and provides the multi tenancy in it. The individual SDN controller runs in each virtual bridge in the VTN and either the same or different traffic policy routing algorithm is implemented in every controller. Thus the complexity of the network is simplified as well as to minimize the infrastructure expenditure. In our proposed work, the VTN Based Energy Efficient Traffic Policy (VTNBEETP) algorithm is implemented to minimize the energy consumption of Open Virtual Switches (OVS). Thus, we simplify the network dependency as well as improvise the energy conservation in the proposed system compared to the traditional networking system.
