The working set of flows is going to be dependent on your environment. There are lots of ways to generate traffic, but you should be tuning OVS for your workload. I'm not clear on your interest in ovs-controller. It's really just meant to test OVS's ability to be remotely configured--it's jus

Thank you Justin, Could you please tell me how can i regenerate these many number of flows for testing so that i can configure threshold based on that,when i tried iperf with 1B and udp flow didn't increase and there were no packet loss.Is ovs-controller generate flow based

I'm guessing the traffic is bursty or ovs-vswitchd was busing doing other work and the queues overflowed. --Justin On May 27, 2013, at 9:34 AM, kevin parker wrote: > Justin, > Even at 85-90% CPU usage i am seeing increased lost count,initially > i faced high lost count when ovs-vswi

Justin, Even at 85-90% CPU usage i am seeing increased lost count,initially i faced high lost count when ovs-vswitchd was at 100%.So what can be the reason for dropped packet even with 10% free cpu available. regards, kevin On Mon, May 27, 2013 at 9:40 PM, Justin Pettit wrote: > We've

We've made a lot of improvements in flow set up rate since version 1.4, so upgrading to a more current version (we're on 1.10 now) will likely help. We're currently working on multithreading the OVS userspace and adding support for wildcarded flows in the kernel, which should substantially impr
