Hi Lisa,

For the way using the Deep Packet Inspection, I guess you can use "Snort
Integration".
http://ryu.readthedocs.io/en/latest/snort_integrate.html

Snort provides the DPI using the OpenAppID, you can detect which communications
are e-mail, video or other services.

But please note that the implementation of this integration might be too old and
has issues on it. When you got some issues, feel free to report them!

Thanks,
Iwase

Dear all, I am new to Ryu-Controller.

In my project, I would like to implement a multipath routing for different applications (services) based on SDN (mininet and ryu-controller). The highest priority application will go through the best path, the second highest priority will go through the second best path, and so on.

To realize this idea, I would like to implement the application-awareness of every single service. So by recognizing the specific application, this application can be directed to a specific path. To do the application-awareness, I found there are two methods, they are: Deep Packet Inspection and Machine Learning methods.

By this email, would you mind to give me some hints or share your experience how to implement the application-awareness in Ryu-Controller? thank you very much


best regards,

lisa
