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
  • FlowVisor Version : 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 An OpenFlow Controller which is a NOX module. Not covered here.
  • 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 Findings

Initial review of the FlowVisor deployment page and FlowVisor found the following issues.

Enterprise GENI How-to

Install and Configure FlowVisor

Using instructions from, installed the Ubuntu package FlowVisor Version First, add the following to /etc/apt/sources.list file:

   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/ 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
  java.lang.RuntimeException: SSL Key Store file not found: '/usr/etc/flowvisor/mySSLKeyStore'
  Please generate with `fvconfig generateCert`
        at org.flowvisor.api.APIServer.spawn(
        at org.flowvisor.FlowVisor.main(

  $ sudo fvconfig generateCert
  Trying to generate SSL Server Key with passwd from scripts/

  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

Issues found, captured in email. (and bugs?)

Install NOX

Followed the NOX Installation instructions from the web site. only evaluated Ubuntu instructions. Install dependencies:

$ cd /etc/apt/sources.list.d
$ sudo wget
$ sudo apt-get update
$ sudo apt-get install nox-dependencies

Downloaded the NOX source code, but had to install the following undocumented packages for the instruction to work:

$ sudo apt-get install git-core

NOX installation

$ git clone git://
$ cd nox
$ git checkout zaku 
$ ./ 
$ mkdir build/
$ cd build/
$ ../configure
$ make -j 5

Followed the Using NOX instructions from the web site.
