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 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
  java.lang.RuntimeException: SSL Key Store file not found: '/usr/etc/flowvisor/mySSLKeyStore'
  Please generate with `fvconfig generateCert`
        at org.flowvisor.api.APIServer.spawn(APIServer.java:85)
        at org.flowvisor.FlowVisor.run(FlowVisor.java:143)
        at org.flowvisor.FlowVisor.main(FlowVisor.java:191)

  $ sudo fvconfig generateCert
  Trying to generate SSL Server Key with passwd from scripts/envs.sh
  Generating cert with common name == mallorea.gpolab.bbn.com

  $ 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

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:

</rspec>
