[Ryu-devel] All the links of the topology not getting discovered.

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

[Ryu-devel] Unique Flow_ID on datapath

Hi, Is there any unique (flow-name or id) to differentiate between flows on a particular datapath ? In my application I need to take actions on particular flow entries and not all of them, it would be helpful if there is something like this. I looked up at RYU documentation but was unable to find

Hi Every One, I am trying to write an application that does topology discovery. I added the a function def get_topology_data at the end of my application I ran the controller with the command: "ryu-manager ryu.app.myswitch --observe-links" and then the mininet with my custom. However, the event Ev

[Ryu-devel] STP- Blocking - Static Routing

[Ryu-devel] Setting Default Routes in custom topology.

Hi, I am trying to set default routes in routers in my custom topology. My topology has loops, so to start the controller in using the command "ryu-manager ryu.app.simple_switch_stp_13 ryu.app.rest_router ryu.app.ofctl_rest" I am using python requests to make REST requests, specifying the destinat
