Research work provides efficient security which protects network resources from internal and external threats. Network virtualization is used to provide users with well-organized, controlled, and safe sharing of the networking resources. It also ensures privacy of data and integrity in Software-defined data center (SDDC) whose infrastructures is virtualized and distributed as a service. SDDC helps to broaden the virtualization concept which makes it more secure. The complete infrastructure is distracted from hardware and implemented via software. One of the core components of SDDC is SDN (Software defined networking) that includes network virtualization. SDN requires the method named Open Flow for the Control plane to communicate with data plane (forwards those incoming packets to the destination). SDN and Open Flow with Virtual LAN are used to concentrate on security issues in data centers. An integration of Software Defined Networking and Open Flow (SDNOF) with VLAN Virtual Server Security (VVSS) architecture is presented to address distinct security issues in virtualized network. The Software defined networking and open flow with VVSS is introduced for more secured protection and to maintain compliance integrity of servers in DCN.

Existing IP routing algorithms have been developed mainly for non-VLAN networks. For these routing algorithms to work, an end station must be attached to its associated network. The introduction of VLAN has, however, allowed the physical location of the end station to be changed from time to time. Therefore, some extra mechanism is required to support routing in VLAN environment. Existing approaches have some drawbacks in terms of inefficiency in traffic forwarding and switch software complexity. In this paper, a simple and efficient method for routing over IP subnet VLAN in Ethernet is proposed. This method has been implemented in hardware and found to work correctly. Various measurements and analyses have been performed to verify the efficiency of this protocol.
