I have a added import ryu.topology.api to my simple_switch.py and I am
running it as
bin/ryu-manager ryu/app/simple_switch.py
According to my understanding,
It runs ryu.topology.switches.Switches because Switches is the class in
that python module (ryu.topology) that inherits app_manager.RyuApp.
Is my understanding correct?
Does this also mean that once the Switches is loaded as an RyuApp
when the framework sends ofp_event.EventOFPPortStatus to an application
program that is in the MAIN_DISPATCHER phase.
it calls the port_status_handler() inside Switches.
https://github.com/karthik82/ryu/blob/master/ryu/topology/switches.py#L611
when the framework sends ofp_event.EventOFPPacketIn to an application
program that is in the MAIN_DISPATCHER phase
it calls the packet_in_handler() inside Switches.
https://github.com/karthik82/ryu/blob/master/ryu/topology/switches.py#L683
If the above understanding is correct, then what about the order in which
packet_in_handlers are called?
is it Switches packet_in_handler followed by simple_switch.py
packet_in_handler()
Any help is greatly appreciated.
Thanks & Regards,
Karthik.
