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.x 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.

Reviewed several versions of the foam package (0.2.9, 0.2.11). Ran into several issues:

  • Advertisement rspecs do not have the component_manager_id in the openflow:datapath element
  • Advertisement rspecs have dpid attribute in the datapath element.
  • Foam package was corrupted in re-install due to process not being stopped before uninstall.

The expedient review ran into to blocking issues that could not be resolved and evaluation was stopped.

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:
