Hello Lisa If by routing applications you mean, routing different applications traffic through different paths or multipaths, then you need to start to think in a way to identify the different applications network traffic. Ryu can surely implement FlowMods in Openflow switches to filter different types of IP traffic, based on their port use.
Deep Packet Inspection and Machine Learning are two different ways to achieve the traffic identification, but you must be aware that to have a controller performing such analysis, it means that the controller needs to receive a big amount of data. So, you will also have to think in how to scale the controller, in order for it to handle the amount of data to perform both types of traffic analysis, since an OpenFlow Switch is only intended for filter and switching traffic, not for deep packet analysis or machine learning processing. The controller will have to do most of the analysis work. Search for academic papers related to this subject in order to learn the current state of art. Good luck!
