Re: [ovs-dev] Query regarding active flows in kernel space

The userspace polls the kernel about every second to check counters and activity for each flow. The userspace determines when a flow should be deleted and tells the kernel to do it (ie, the kernel doesn't decide when flows should be deleted). --Justin On Oct 15, 2012, at 8:38 AM, ankur dwive
