1 Software Defined ing Seminar Introduction - Summer Term 2014 Net Jeremias Blendin jblendin@ps.tu-darmstadt.de Prof. Dr. David Hausheer hausheer@ps.tu-darmstadt.de PS Peer-to-Peer Systems Engineering Prof Dr. David Hausheer Dept. of Electrical Engineering and Information Technology TUD Technische Universität Darmstadt Rundeturmstr. 10, D Darmstadt, Germany Tel , Fax author(s) of these slides including research results of the research network PS and TU Darmstadt otherwise as specified at the respective slide 1

2 Software-Defined ing hardware often considered as black box Closed-source, vendor specific solutions Hard to deploy and test new network protocols and routing mechanisms? OpenFlow as idea to overcome this problem Provide standard interface to interact with flow tables of network switches Still allow vendors to keep proprietary routing instructions secret that differentiate one company's hardware from another 2014 author(s) of these slides including research results of the research network PS and TU Darmstadt otherwise as specified at the respective Source: slide [2]

3 Software-Defined ing Abstract concept: Separation of control and data plane Logically central control of the network infrastructure Two planes, different objectives Control plane: topology discovery -wide traffic management Data plane: Control Protocol Control Plane Line-speed data forwarding/ switching/routing Switch data Switch Do as much in hardware as possible Data Plane 2014 author(s) of these slides including research results of the research network PS and TU Darmstadt otherwise as specified at the respective slide 3

4 SDN: General Architecture Northbound Southbound East-Westbound 2014 author(s) of these slides including research results of the research network PS and TU Darmstadt otherwise as specified at the respective slide 4

5 OpenFlow Overview OpenFlow defines the standard communication protocol between network switch and controller Control Plane A number of vendors already sell OpenFlow-enabled network switches (e.g. Cisco, HP, IBM, NEC) Protocol specification: Numerous controller frameworks available: OpenDaylight, Ryu, NOX, Trema, Floodlight, etc. Data Plane Picture source: [1] 2014 author(s) of these slides including research results of the research network PS and TU Darmstadt otherwise as specified at the respective slide

6 Steps of Interaction uses the OpenFlow protocol to install rules at the switch Rules are defined over a set of packet header fields Flows are installed at flow table of switch according to the rules If a packet does not match any rule, the controller is contacted to decide what to do Picture source: [1] 2014 author(s) of these slides including research results of the research network PS and TU Darmstadt otherwise as specified at the respective slide
