Hi!
I use ryu (especially 'ryu/ryu/app/gui_topology') to visualize switch
topology.
My use case is to detect failure of a switch and define new
bypass-route(flow).
To emulate a switch failure, I use 'switch stop/start' mininet GUI
commands and watch topology by 'gui_topology.'
Unfortunately,'gui_topology' often miss-track right dpid.
It seems 'dpid' values do not treat as d3 data primary-key.
Hope this patch helps!
Thank you in advance,
N. Arakawa
