Dears,

It is my first time to Ryu.
I want to run an application that depends on:
1- openflow events (like simple switch app you provide in the tutorial) and
also
2- external events (provided by an external Data Base - DB).
In fact, I have a python scirpt that periodacally check my data base to get
new modification. I am wondering how can I integrate it in my Ryu
application in order to be updated from my data base and consequently
change the behaviour of my ovs switch ?
I want to run only one application (one source file) because there some
variables to be shared and I want to know how to integrate my source code
(that gets the DB update) into my Ryu application (that is very closed to
simple_switch.py) ?
If you recommand using two separte file please tell me how to change my DB
script in order to be a Ryu application ?

Thanks in advance.
Regards
