Ryu: convert datapath to switch IP address

Currently, I'm writing an application on top of Ryu, the Open-source OpenFlow Controller.

To create an OF-Config connection (or OVSDB connection), I think I have to get the IP address of each switch connected to the Ryu controller. However, I cannot find the API that converts the Datapath object or datapath id to the IP address of the switch.

So, if there is such an API, I want to know about it. If not, I'm looking forward to receiving some comments about the way to make the connections without the IP addresses.

Solution

@set_ev_cls(event.EventSwitchEnter)
def switch_features_handler(self, ev):
    address = ev.switch.dp.address
    dpid = ev.switch.dp.id

"address" is a tuple of (ip_address, port) and "dpid" is the datapath id.
