# Project Description:
# This project is created by Li Jian for his master degree dissertation project, 
# which is an OpenFlow Implementation over Named-Data Networking. In this project, 
# a new designed OpenFlow SDN is designed to run over NDN and to offer control-plane
# for NDN nodes. 

# In this application, there are several main components, and all of these components
# can run on NDN nodes, specifically on the nodes of Minindn simulator. All of these 
# components are written in Python3.6. 
# Controller.py  is the main component used as a OF-SDN controller, which needs only  
# one node to run it.
# Node.py is the other main component which should be running on all other NDN nodes. 
# It is used to monitor the status of NDN nodes and to communicate with the controller.
# It also has the ability to configure the nodes.

# There are other two components used for test, testproducer.py and testconsumer.py. 
# They are just used to send 'Interest' and response it with 'Data'.  

# This application is also based on adjusted Minindn simulator, which means that if 
# if you want to the full function of this application, the Minindn simulator environment
# needs to adjust.  The modification has been described in Li Jian's dissertation paper 
# in detail. 

# Because of the limitation of time, this application may include some imperfections or errors,
# The author will be very grateful to you for pointing out of these mistakes. The author's 
# email address has been listed in the front of this page.
