Anyway, unless required for a specific reason, you may just go with the easier and working option for your thesis.<br /><br />Good luck with your work.<br /><br />Regards,<br />Pradeeban.Pradeeban Kathiravelu, Ph.D.https://www.blogger.com/profile/02966629782470028375noreply@blogger.comtag:blogger.com,1999:blog-1478030848346376035.post-90327615543777499722015-12-01T13:07:23.845+00:002015-12-01T13:07:23.845+00:00Hi Pradeeban,

Few attempts on using Lithium (latest version), however fails to log on to web interface (http:127.0.0.1:8080). Until i download the Helium. Now, i can run Controller but got problem with the communication. I just found your blog today, and i will go through it. Thanks for sharing your knowledge. <br /><br /><br />Rgds,<br />Dianadeyanahttps://www.blogger.com/profile/11639098421957608859noreply@blogger.comtag:blogger.com,1999:blog-1478030848346376035.post-57344853584086731382015-12-01T12:49:41.207+00:002015-12-01T12:49:41.207+00:00Hi Diana,

If you are in a very early stage, you may instead give a try to Floodlight as well. Many of my friends (I have not used it extensively) reported that Floodlight is easier to begin with, compared to OpenDaylight. You may have a look at http://kkpradeeban.blogspot.com/2015/09/configuring-mininet-with-floodlight.html<br /><br />Just keep your options open.<br /><br />I may not be able to reply all the questions (I am just a second year PhD student).

But when i was trying to create topology on mininet by using this command sudo mn --controller=remote,ip=192.168.190.13,port=6633 or even sudo mn --controller=remote,ip=127.0.0.1,port=6633, nothing happen in GUI. <br />I am suspecting that the ODL controller doesn't communicate with mininet, however i am not sure how to trace the prob.
