Programmable virtual router implementation method based on SDN architecture and Ryu controller technology

Abstract

The invention discloses a programmable virtual router implementation method based on an SDN architecture and a Ryu controller technology, and the method comprises the following steps: S1, obtaining a virtual router: obtaining the virtual router based on the SDN architecture and the Ryu controller technology; s2, virtual router communication is completed, wherein virtual Ethernet network cards veth of which the number is the same as that of bottom hardware network interfaces are created in each virtual router; s3, virtual router data packet parallel processing: establishing a multi-protocol type data packet parallel processing system to complete data packet parallel processing; s4, data packet shunting and forwarding of the virtual router: shunting and forwarding the data packets according to different types of forwarding granularities; and S5, carrying out accelerated forwarding processing on the data packet of the virtual router. According to the invention, by establishing the accelerated forwarding system, the programmable virtual router can shorten the searching process of the data packet in the processing process of the data packet, reduce the searching times of the routing table, reduce the routing searching burden, and achieve the purpose of accelerating the forwarding of the data packet.
