Research Of Virtual Switching Based On Openflow

In recent years, with the rapid development of Internet, traditional network architectures become more complex, more and more bloated agreement, the traditional network urgent needs new network architectures and more efficient network management. However, the traditional network equipment is relatively closed, there is no uniform open interfaces, and developing their own protocols often require long development cycles and high development costs, so innovation of the new agreement is often difficult. In order to accelerate the development of network technology in recent years proposed concept SDN(Software Defined Network), the upcoming network separation of control and forwarding and provide development interface for developers. The SDN openflow agreement is the most mature of the south to the agreement, in openflow, the controller focused on decision-making control, and switch entirely focused on forwarding, making the network is highly flexible and powerful programmability.OpenFlow technology can use to exchange data in a virtual environment, in order to simplify management and cost savings.This paper describes the architecture and openflow SDN technologies and network environment by building openflow virtual switching technology research.
