Hi Muthukrishnan, there is no golden standard behind this value. Setting it to 100ms or even lower value will result into low latency system but this also decreases throughput of system. If you have few switches and little no big requirement on flows per second throughput then 100ms might sui

[openflowplugin-dev] Problems with load-balancing of OVSs in a cluster?

2017-02-16 Thread Sela, Guy
Hi, I have a 3-node cluster which I connect 200 OVSs to. Each OVS is configured with all the 3 ODLs as managers. When checking which ODL took ownership on which OVS, I expected something equally distributed but got: ODL 1: 14 switches ODL 2: 46 switches ODL 3: 140 switches Is this normal? Than

Hi again Luis, I managed to get single layer serialization to pretty stable state, but I have 1 quick question, and hopefully you will know the answer. According to test result from flow-services CSIT here: https://logs.opendaylight.org/releng/jenkins092/openflowplugin-csit-1node-flow-services-

Adding Anil since I asked him about this last week. I think the default behavior for ownership is simply which ODL receives the incoming connection first becomes the owner. I might have that confused with the ovsdb side though. On Thu, Feb 16, 2017 at 9:25 AM, Sela, Guy wrote: > Hi, > > > > I h

Hi Tomas, The reconciliation test does the following: 0) Enable stale-flow entry feature (otherwise step 5 will not work) 1) add 2000 groups + 1000 flows (+10 table-miss) 2) Disconnect network 3) Remove 20 groups + 10 flows 4) Reconnect network 5) Check groups and flows are deleted from switch (

Hello openflowplugin developers , I have been using lithium release of opendaylight. We are seeing ODL crashes with error mentioned in the subject line , when we test the scenario of frequent connection flap . If this issue has been already addressed as part of the latest release , could anyo

Hi Santosh, Looks like your controller crashed while spawning a new native JVM thread, because your JVM Is out of native heap space. Can you increase your native heap space and see if you still hit the issue (it might take longer to recreate the issue). Meanwhile if you have the heapdump, please

Hi Anil , Thanks for your response .. We are running with following memory option , I think which is sufficient for ODL instance having 150 OF connection. -Xms128M -Xmx31393m -XX:MaxPermSize=15696m Any thoughts on this ?? We would be trying to recreate this issue in order to get heap dump ...

Hi Santosh, Couple of questions - a) Does crash happen instantaneously – I mean within shorter intervals or degradation is progressive over time ? b) since you emulate the flaps, is it possible to control the frequency of flapping with your emulation ? If (a) holds true or (b) is po

Thank you for explanation Luis. I missed step 3 when I was going through test report. At least now I know where to search for issue and after this last one will be fixed, single layer model implementation will be finally finished, because other than this it is not causing any more regressions bo
