Sorry, I don't have any idea...

But do you have any rough idea, how many links should a topology have to not hit
performance limit?
This is my systems specs.
I need EventLinkAdd and EventLinkDelete to work properly as I am planning to
introduce multiple link failures from mininet.
I started with 62 nodes, 107 links and trimmed my topology to 30 Nodes and 43
Links(86 bi-directional) and found, I was able to discover the full topology but
EventLinkDelete wasn't triggering when I tried with mininet (link down command).
Now I have 30 Nodes, 32 Links and still EventLinkDelte is not getting triggered
though I see the full topology information in my structures storing their
information in RYU controller.
Thanks!

Hi Taha,
IIRC, the similar problems had reported before on this mailing list.
I think you hit the performance limit of "single" controller in order to use
topology discovery feature against such many switches.
For handling such large topology, how about splitting your topology into
some
sub-topology and having multiple controllers?
Thanks,

Hi
I am using RYU-4.23 and Mininet OVS.
I have a 62 Node topology. When I run my RYU application I noticed that
RYU is not able to discover all the datapaths and links everytime I run
my code. And also when I run (link down command ) in mininet CLI,
EventLinkDelete is not getting triggered everytime I did it. Few times I
was actually able to discover the full topology and EventLinkDelete was
also getting triggered.
Can you please suggest why is this so. I have attached codes below.
Thanks!
Taha
