Introduction To Openflow Presentation Transcript

  • 1. Introduction to OpenFlow MEULLE Michael, DAAR Waqas CORE-TPN-RIV 23 July 2010 recherche & développement
  • 2. Outline  Background  Motivation  OpenFlow overview  OpenFlow Concept  OpenFlow protocol  OpenFlow Messages  How OpenFlow works?  Conclusion 2 recherche & développement
  • 3. Background  Internet is closed for Innovations  We like to do new experiments  Mobility management  New naming/address schemes  Network access control  …… 3 recherche & développement
  • 4. What is OpenFlow?  Put an open platform in hands of researchers/students to test new ideas at scale through production networks.  An open development environment for all researchers  Give access to flow tables in switches  lookup tables, access control list, etc..  Control packet forwarding in routers and switches. 4 recherche & développement
  • 5. OpenFlow Architecture Figure 1: OpenFlow Architecute [1] 5 recherche & développement
  • 6. OpenFlow Protocol Support three message types Controller   Controller-to-switch messages OpenFlow protocol • Configuring the switch • Exchanging switch capabilities • Managing the Flow table  Symmetric messages OpenFlow switch • Send in either direction • Diagnose problems in switch controller connection  Asynchronous messages • From switch to the controller • Announce change in network state, swtich state etc. 6 recherche & développement
  • 7. OpenFlow Controller  Openflow controller is a centralized entity for the entire OpenFlow network.  NOX [4] is an open source OpenFlow controller.  simplified platform for writing network control software in C++/ Python.  Researchers can write a software and plugin to NOX for testing their idea. 7 recherche & développement
  • 8. Packet processing in OpenFlow Network Figure 2: Processing of a packet in Openflow network [1] 8 recherche & développement
  • 9. OpenFlow Table Entry Figure 3: OpenFlow Table Entry [2] 9 recherche & développement
  • 10. OpenFlow switching mechanism Figure 4: Switching of packets in OpenFlow network [3] 10 recherche & développement
  • 11. Conclusion  Test environment for future Internet technologies  Setup experiments at the flow level  Setup experiments at the packet level 11 recherche & développement
