With the introductions of the development and further applications of SDN network, this paper describes a new architecture based on the OpenFlow protocol which is consist of four virtual levels: the application layer, the virtual platform, the control layer and the physical layer. And by studying the features of SDN and the OpenFlow protocol, it makes a theoretical foundation and an effective solution...
Innovation networking technology led to the traditional TCP / IP network towards a more high-speed, open, intelligent direction. Based on the theory of SDN and the open-source controller, developed a four-tier structure SDN control platform, respectively, to achieve and maintain the connection is established, the message adaptation, application interface and other functions. Design and implement adaptation...
According to the communication structure of CAN BUS network on EV, this paper works out a SAE J1939 application layer protocol meet the system functional requirements, and designs the software and hardware for the system. First, design the CAN BUS work nod for EV, including the master node, the light node, air conditioning node, doors and instrument node, etc, and the draw the CAN BUS topology diagram...
