Hi Taha,
Hmmm... I haven't tried yet though, the following parameters seems to be
configured. But sorry I don't know those parameters meanings further...

Thanks,
Iwase

Well, What I observed is - Number of Nodes: 13, Number of Edges:21.
Is there a way this could be increased in terms of number of edges and nodes?
Thanks!

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,
Iwase

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
