    299299  - More information about "/tmp/postboot_script_exo.sh":
    300300   It is a "hook" to the !LabWiki interface. Experimenter run this so that !LabWiki knows the name of the slice and the hostname of the particular node that OML/OMF toolkits are running on.
    301   - More information about "/tmp/of-topo-setup/lb-setup":
    302    "lb-setup" is to setup the load balancing switch. The source code as well as explanation is as follows:
    303    {{{
    304    #!/bin/sh
    305 
    306    /tmp/of-topo-setup/prep-trema       # install all libraries for trema
    307    /tmp/of-topo-setup/ovs-start           # create ovs bridge
    308 
    309    cp /usr/bin/trace-oml2 /usr/bin/trace        # a hack to the current LabWiki --> needs to be fixed
    310    cp /usr/bin/nmetrics-oml2 /usr/bin/nmetrics       # a hack to the current LabWiki --> needs to be fixed
    311    # download the load balancing openflow controller source code to user directory
    312    wget http://www.gpolab.bbn.com/experiment-support/OpenFlowExampleExperiment/ExoGENI/load-balancer.rb -O /root/load-balancer.rb
    313 
    314    INTERFACES="192.168.1.1 192.168.2.1 192.168.3.1"
    315 
    316    # wait until all interfaces are up, then fetch the mapping from interface name to its ip/MAC address and save this info in a file /tmp/ifmap
    317    /tmp/of-topo-setup/writeifmap3
    318 
    319    # add port to the ovs bridge
    320    /tmp/of-topo-setup/find-interfaces $INTERFACES | while read iface; do
    321        ovs-vsctl add-port br0 $iface < /dev/null
    322    done
    323 
    324    # create port map save it to /tmp/portmap
    325    ovs-ofctl show tcp:127.0.0.1:6634 \
    326        | /tmp/of-topo-setup/ovs-id-ports 192.168.1.1=outside 192.168.2.1=left 192.168.3.1=right \
    327        > /tmp/portmap
    328    }}}
     301  - Take a look at the script for setting up the switch node, it is located at the node at "/tmp/of-topo-setup/lb-setup".
