Thanks for the reply.
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,
Hi everyone;
How i can disable/enable a specific swicth port with ryu?
Thanks.

Hey Iwase,
Split means really divide the flow I dont know if would be like a load
balancing (I think it is)
For example the image below
But I dont know if this would be possible using the group table.

Hi PA,
Thanks for the response.
Regarding use case1 (1.- Have an SDN domain look like a BGP router, for
example, a central office that grooms end-users and interacts with the

Hi Alvaro
The best way, if you are in OF1.3 is to split up things. Look at the
documentation regarding VLAN traffic. When I have VLAN traffic, I create a
specific table where I differentiate between non-tagged and tagged VLAN
traffic and if I need to get down to IP in VLAN traffic, I add an
additi
Hi Suresh,
I see two use cases:
1.- Have an SDN domain look like a BGP router, for example, a central
office that grooms end-users and interacts with the ISP's infrastructure
2.- Researchy kind of things like using BGP-4 for a possible East-West
interface between SDN domains,

Hi,
Thank you for the information!
In my environment, the simulation completed successfully.
I think your problem is lack of resource, especially CPU performance.
While Monitoring resource, CPU usage eventually reached 100%, but Memory
usage has hardly changed.
My CPU is : Intel(R) Core(TM) i
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-topo
Hi Soliman,
"ryu.topology" provides such feature, I guess.
How about the following APIs and events?

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 everyti
Hi Carlos,
What does "split flows" exactly mean?

If you specify OFPGT_SELECT, switch will execute "one" bucket in the group and
