OpenFlow Configuration Point: OF-Config spots OF-Config commands related issues. OpenFlow Capable Switch: It is a switching device that composed of numerous ports and queues, which can be physical or logical. OpenFlow Logical Switch: It consists under OpenFlow capable switch itself, which assigns a part of ports and queues that make up an OpenFlow capable switch, see Figure 6. According to OF-Config version 1.1, it separates itself from any presumptions that an operator would run Flow Visor to attain numerous logical switch abstractions inside physical switch. The OF-Config Point can be positioned in the same server like OpenFlow controller or within conventional network management products. This point is capable of managing more than one OpenFlow-capable physical or virtual switches. The OF-Config Point can handle many OpenFlow capable switches and vice-versa see Figure 6. It can communicate with OF Logical switches. The control point provide IP addresses and port numbers of OpenFlow controller to every single OF logical switches for controlling packet flows through the switches.
