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 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 0.8.1.2 found the following issues.
Enterprise GENI How-to
FlowVIsor Installation and Configuration
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

--- 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?)
FOAM Installation and Configuration
Followed the install from package instruction found at the [ https://openflow.stanford.edu/display/FOAM/install FOAM install] page. Created a file foam.list in the directory /etc/apt/sources.list.d/ containing the following:
deb http://updates.flowvisor.org/openflow/downloads/GENI/DEB unstable/all/
Installed the foam package and initialize the FOAM database:
$ sudo apt-get update $ sudo apt-get install foam $ sudo -u www-data foamctl init-db Certificates Directory [/opt/foam/etc/gcf-ca-certs]: Site Tag [mallorea.gpolab.bbn.com]: FlowVisor Hostname: mallorea.gpolab.bbn.com FlowVisor XMLRPC Port [8080]: FlowVisor JSON RPC Port [8081]: fvadmin user password:
Set up the FOAM administrative account password:
sudo foamctl set-password
Removed the default nginx site:
sudo rm /etc/nginx/sites-enabled/default
Installed a trusted root certificate from pgeni.gpolab.bbn.com, bundled the certificate and started the FOAM services:
$ sudo wget http://www.pgeni.gpolab.bbn.com/ca-cert/pgeni.gpolab.bbn.com.pem -O /opt/foam/etc/gcf-ca-certs/pgeni.gpolab.bbn.com.pem $ sudo wget https://emulab.net/genica.bundle -O /opt/foam/etc/gcf-ca-certs/emulab.pem --no-check-certificate $ sudo foamctl bundle-certs $ sudo service nginx start $ sudo service foam start
Once the FOAM services are started generated a simple RSPEC using instructions from the Example RSPEC and Convert Expedient to FOAM RSPEC page:

NOX Installation
Followed the NOX Installation instructions from the noxrepo.org web site. only evaluated Ubuntu instructions. Install dependencies:
$ cd /etc/apt/sources.list.d $ sudo wget http://openflowswitch.org/downloads/debian/nox.list $ 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://noxrepo.org/nox $ cd nox $ git checkout zaku $ ./boot.sh $ mkdir build/ $ cd build/ $ ../configure $ make -j 5
Followed the Using NOX instructions from the noxrepo.org web site.
$ cd nox/build/src $ ./nox_core -v -i ptcp:6633
Installed the nox-gui pre-requisites and started nox-gui:
$ sudo apt-get install python-qt4 python-simplejson ???
Expedient Installation
Installed Expedient using the git repository instructions found in the Checkout Repository section of the Installing Expedient page, but first had to install pre-requisites:
$ sudo apt-get install python-2.6 $ sudo apt-get install xmlsec1 $ sudo apt-get install libxmlsec1-devel $ sudo apt-get install python-setuptools $ sudo apt-get install python-django $ sudo apt-get install python-django-registration $ sudo apt-get install python-decorator $ sudo apt-get install m2crypto $ sudo apt-get install python-imaging (PIL) $ sudo apt-get install python-dateutil $ sudo apt-get install python-crypto $ sudo apt-get install python-paramiko $ sudo apt-get install python-webob $ sudo apt-get install python-OpenSSL $ sudo apt-get install python-pyquery $ sudo apt-get install sphinxsearch $ sudo apt-get install python-pygments $ sudo apt-get install libxslt-dev $ sudo apt-get install python-zsi $ sudo apt-get install python-mysqldb $ sudo easy_install django-autoslug & sudo easy_install django-renderform
