Dynamic Virtual Switch Protocol Using Openflow

STP Spanning Tree Protocol as an important method to prevent broadcast storms since the 1985 proposed by Radia Perlem, has been widely used. This paper presents anew technology named DVSP-open flow. Compare STP and the STP improved version, this technology can be can be forward data packets dynamic by using Open Flow support switches. This method separates the forward rules and control rules and the network with this method will be able to collect real-time network information and create a virtual switch pool to manager Data forward path, achieve the ability to forward the packet to reach the network to dynamically control Open Flow switch. The technology can effectively suppress network storms, and be able to reduce the packet forwarding delay.
