  17. 17. Competence Center NGNI Fraunhofer FOKUSOpenFlow – An Overview Definition of OpenFlow “OpenFlow: a way for researchers to run experimental protocols in the networks they use every day.  OpenFlow is based on an Ethernet switch, with an internal flow-table, and a standardized interface to add and remove flow entries.” [OFKe08]  Open Flow virtualizes networks through separating control and switching functionality by extracting the routing decision point from the switch into the controller. OpenFlow consists mainly of five elements  OpenFlow Switches: Separation between OpenFlow Network Architecture OFP Switch and Routing/Forwarding functionality. OpenFlow Controller  OpenFlow Controller: Routing decision point. Data  OpenFlow Protocol (OFP): Securely (SSL/TCP) FlowVisor connects OpenFlow Controller and OFSwitch OpenFlow Switches OFSwitch OFSwitch  FlowVisor: Transparent network slicing. OFSwitch  Hosts: User endpoints or attached devices. Host Host
