Hi Soliman, The page you mentioned was written on OCTOBER 5, 2013 and the description might be old (e.g., the default OpenFlow version on Mininet has been changed).
Please refer to the Ryu-Book for running "Switching Hub" application. http://osrg.github.io/ryu-book/en/html/switching_hub.html#execution-of-ryu-application Thanks, Iwase On 2018年02月22日 00:15, Soliman Awad Alshra´a Abdullah TU Ilmenau wrote:
