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

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,

Re: [Ryu-devel] Spliting flows through two ports

Hi Carlos, What does "split flows" exactly mean? > req = parser.OFPGroupMod(datapath, ofp.OFPFC_ADD, ofp.OFPGT_SELECT, > group_id, buckets) If you specify OFPGT_SELECT, switch will execute "one" bucket in the group and not copied like the port mirroring. If you intend

Re: [Ryu-devel] Informing the controller about the first switch Datapath and port number which connected to the host.

Hi Soliman, "ryu.topology" provides such feature, I guess. How about the following APIs and events? https://github.com/osrg/ryu/blob/master/ryu/topology/api.py#L38-L44 https://github.com/osrg/ryu/blob/e6773539b546576c13f7397769d2001c46bbfdaa/ryu/topology/event.py#L169-L186 If you want to

Re: [Ryu-devel] Running multiple controllers

Hi, I think this issue is a problem of Mininet not Ryu. I found the similar script on Mininet's GitHub, but I don't know further. https://github.com/mininet/mininet/blob/master/examples/controllers2.py Thanks, Iwase On 2018年03月21日 00:05, Soliman Awad Alshra´a Abdullah TU Ilmenau wrote: Hello

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

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

Re: [Ryu-devel] Simulation for flow-table attack using ryu

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)

[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

Re: [Ryu-devel] BGP Usecase

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, /PA On 23 March

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 ISP's infrastructure), SDN controller(app) is act as a BGP router, establishes the neighbor relation ships with one

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. 2018-03-23 4:04 GMT-03:00 Iwase Yusuke : > Hi Carlos, > > What
