Re: [Ryu-devel] Host Discovery Implementation in RYU

[Iwase Y. <iwa...@gm...>]

Hi Jara,

First, "ryu/app/gui_topology/gui_topology.py" does not install flows for forwarding
packets as "ryu/app/simple_switch_13.py" doing, and the Mininet hosts can not
communicate each other.
If you want to do ping between hosts, how about includeing "simple_switch_13.py"?
  e.g.) PYTHONPATH=. ryu-manager --observe-links ryu/app/simple_switch_13.py ryu/app/gui_topology/gui_topology.py

Also, IIRC, "gui_topology.py" can not show the hosts and links between them, only
switches and links between those switches on its view.

Thanks
