Enterprise GENI Evaluation

The Enterprise-GENI solution is composed of four main entities:

• OpenFlow-based Substrate Version ??: Switches that communicate using the OpenFlow protocol to the OpenFlow controller. Software version available include
  • ​Indigo
  • Pica8
• FlowVisor Version 0.8.1.2 : Custom-build OpenFlow controller that isolates experiment control traffic.
• Opt In Manager Version 0.2.5 : Administrative application for OpenFlow-based network.
• Expedient Version 4.0.2: Portal for defining experiment resources.

• NOX Zaku branch: An OpenFlow Controller providing flow level control of network traffic.
• SNAC (​http://www.openflowhub.org/display/Snac/SNAC+OpenFlow+Controller+Packages) An OpenFlow Controller which is a NOX module.

Note: * FOAM Version 0.2.2 will replace the Expedient Aggregate Manager and Opt In Manager. Version? Location? Evaluation Time Frame: September 26, 2011

Enterprise GENI How-to

Install and Configure FlowVisor

Using instructions from ​https://openflow.stanford.edu/display/flowvisor/fv_deploy, installed the ubuntu package FlowVisor Version 0.8.1.2. First, add the following to /etc/apt/sources.list file:

deb http://updates.flowvisor.org/openflow/downloads/GENI/DEB unstable/binary-$(ARCH)/

Install package: sudo apt-get update && sudo apt-get install flowvisor

Before proceeding to configuration step, should modify the SSL_KEYPASSWD in the file /usr/etc/flowvisor/envs.sh to define the password to be used by the fv-admin profile:

You can now start the FlowVisor, note if this is a new FlowVisor installation, the SSL keystor must be generated, below is a capture of the process:

  $ sudo /usr/sbin/flowvisor /usr/etc/flowvisor/config.xml 
  Starting FlowVisor
  Running with FV_JVM_ARGS=-server -Xms100M -Xmx1000M -XX:OnError=flowvisor-crash-logger -XX:+UseConcMarkSweepGC
  --- Setting logging level to NOTE

The FlowVisor configuration that is delivered includes sample slices that should be deleted:

  fvctl --passwd-file=/root/.fvp  deleteSlice alice
  fvctl --passwd-file=/root/.fvp  deleteSlice bob

Minor issues found, with setting password and paths. (expand)
