  • 1.  Flow Measurement in mininet (One Ping Only)

    Posted Feb 13, 2015 03:31 PM

    Hello All

     

    If we want to build the one-ping-only application, how can we do that? Is the following command correct?

     

    ./gen-sdn-app --template one-ping-only --directory ~/HPVANEx1/ \
    --app onepingonlyex1 --company hp --subject OPOEx1 \

     

    Also, after building the application and importing into the controller and eclipse, how we can run it on the controller webpage and see the results when the controller interacts with the network emulated in mininet?

     

    I appreciate all your help in advance.

     

    Thanks

    Best

    Hello All

     

    I want to build the one-ping-only application and I have used the following command.

     

    ./gen-sdn-app --directory ~/HPVANOPOExnew/ --template one-ping-only \
    --app opoexnew --company hp --subject Switchoponewex --app-name "oponew" \
    --company-name "Hewlett Packard" --description "Application for Flow Measurement" \
    --rest-path switchesopoexnew

     

    Accordingly I have the following directory


    HPVANOPOExnew/opol-bl/

     

    where there are one "src" folder and two files including "opo.descriptor" and "pom.xml"

     

    After setting the proxy using export "http_proxy=http: ..." and "export https_proxy=https: ...", I am using "mvn clean install" command, but I am getting the following error. I was wondering what is the problem and how I can build the "one-ping-only" application?

    Hello All

     

    It seems that every time we have to: 1) Disable the App; 2) Run the Mininet and create the topology; 3) Enable the app 4) ping hosts one-by-one

     

    Thanks

    Best
