  # Constructor of the class 
 def __init__(self, connection, transparent):
     # track the connection to the switch to send messages
    self.connection = connection
    self.transparent = transparent

    # Add listener events to handle connection events from OpenFlow switch 
    connection.addListeners(self)
    log.debug("Initializing VideoCache, transparent=%s", str(self.transparent))

    # Turn on Nicira packet_ins. 
    # Nicira extensions to support openFlow 1.0
    msg = nx.nx_packet_in_format()
