Centralization of Network using Openflow Protocol


Traditional network is used have distributed nature which face complexities while modifying, monitoring, securing the network. The centralization of network is proving very effective in terms for management, implementation of new applications, monitoring the network. The programmable network using programmable devices helps to implement centralization of network successfully. To reduce the latency in the network the control parameters of control plane are used for making the forwarding decision by the centralized controller. Software Defined Network (SDN) is emerging technology having the centralized policy to design cloud network topology. The abstraction of control plane from data plane is isolating the control parameters from the flow of packets for making an efficient forwarding decision by programmable device. This device is known to be controller; it also reduces the complexities to process the data overhead. The OpenFlow protocol is used for abstraction and transferring the control parameters over secure channel. The protocol enables the enterprise to design well managed and secure cloud. In this paper, the experimental test bed is built which provides the centralized System Center Virtual Machine Manager (SCVMM) controller in the private cloud. The cloud provides its virtual Platform as a Service (PaaS) to the client by creating multiple Virtual Machine instances on single machine. The Virtual Private Network is created by using the Network Virtualization Generic Routing (NVGRE) tunnelling Protocol for the client to reach up to the hosted platform.
