碩士 === 東海大學 === 資訊工程學系 === 101 === OpenFlow mechanism is a next generation networking protocol. It speeds up network performance by separating the control layer and the data layer. It can implement the real QoS function. Users who really need network speed can get their resources, or decided by the priority which system defined. To implement OpenFlow mechanism, we need two elements, the switch which supports OpenFlow, whatever it is physical switch or virtual switch, and a controller to send flow setting packet, to control the switch flow table. When you start using OpenFlow, the switch or router provide function, like RIP, OSPF, EGP routing protocol, or firewall, QoS, Anti Virus, NAT, is not important. Because OpenFlow focus on provide a standard Application Programming Interface, let users can design function which they want, and do not use the manufacturers good proprietary operating system and functions. OpenFlow allows users to freely choose vendors, not limited by specific vendors and specific functions. The main goal of this thesis is to create a OpenFlow switch monitor system. It can find out all host and traffic pass through switched under controller, and provide a simple web page which the network administrator can modify each flow priority. Allow network administrator to manage the whole network more easily.
