FlowVisor

FlowVisor is a specialized OpenFlow controller that creates slices within an OpenFlow network, allowing the same physical deployment to support multiple controllers. Here we describe the setup/installation FlowVisor 6.0 on Ubuntu 9.10.

prereqs

The latest FlowVisor (which supports OpenFlow 1.0 at this time) is based on java, requiring the following packages:

  • ant
  • sun-java6-jdk

It is assumed that you have OpenFlow installed and in working condition.

installation

  1. install above-mentioned packages
  2. pull from git repository:
     git checkout -b flowvisor-0.6 origin/flowvisor-0.6
    
    we need to take this step to make sure we have the right package.
  3. choose the proper version of java with update-alternatives --config java
     root@internal2:/opt/flowvisor# update-alternatives --config java
    There are 2 choices for the alternative java (providing /usr/bin/java).
    
      Selection    Path                                      Priority   Status
    ------------------------------------------------------------
      0            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      auto mode
      1            /usr/lib/jvm/java-6-openjdk/jre/bin/java   1061      manual mode
    * 2            /usr/lib/jvm/java-6-sun/jre/bin/java       63        manual mode
    
    make sure to have java-6-sun version of java chosen as the alternative as shown above.
  4. cd to flowvisor directory; if ./configure doesn't exist, run ./boot.sh
    sh ./boot.sh
    
  5. run ./configure
  6. run make:
    sudo make CFLAGS="-I/usr/lib/jvm/java-6-sun-1.6.0.20/include -I/usr/lib/jvm/java-6-sun-1.6.0.20/include/linux"
    
    The paths for CFLAGS should be based on what you get if you do a locate jni.h:
    $ locate jni.h
    /usr/lib/jvm/java-6-sun-1.6.0.20/include/jni.h
    
  7. run make testsand make install

configuration

Configuration files should be placed in a directory called "flowvisor-conf.d".

FlowVisor reads any files ending in .guest and .switch in the directory. The first describes policies, and the latter, the datapaths associated with the policies.
