OpenFlow Experimenter: Experimenter ID

Hi guys,

This is a pretty niche question that I couldn’t find an answer to online. Hoping someone here can share their expertise. For my SDN related masters thesis to work I need to make a substantial number of extensions to the southbound api protocol OpenFlow. These extensions are necessary to define new messages, actions etc sent between the controller and switches. In the OpenFlow documentation an “Experimenter ID” is needed which is either a vendors IEEE OUI or assigned by the ONF. As an MSc student I do not have a valid IEEE OUI to generate this ID from and am yet to receive a response from the ONF regarding assignment of my own ID. Would use of an “unofficial” Experimenter ID that I choose myself work or will a bad Experimenter error always be thrown? Should I try different ID’s until one works or is it better to cut my losses and change the focus of my masters? I need to find out if a work around is possible so I do not waste any more time on this. Thank you for any responses.
