[ovs-discuss] Unexpected behavior of counters when installing new flow

2013-04-29 Thread Tmusic
Hi, I'm experiencing some unexpected behavior from the flow counters when using wildcarded flow entries (with OpenFlow). Steps to reproduce: - Start a udp flow ex. 10.1.4.1=>10.1.6.1 - Install wildcarded entry 10.1.4.0/30 => 10.1.6.0/30 ==>After some time counters (ovs-ofctl dump-flows) indicate

I checked it multiple times and it seems to be 2.5-2.6s on average openvswitch is polled for its counters using the openflow protocol Is this interval determined by openvswitch or by the linux kernel? Thanks! 2013/3/15 Ben Pfaff > On Fri, Mar 15, 2013 at 09:24:05PM +0100, Tmusic wr

Hi, I'm using ovs with openflow and have noticed that flow stats seem to update about every second. So first question: Is this correct? Is it possible to have it update more often? (command line arg, or does it have to be changed in the source) I suppose this will imply heavier load (more commun

Hi, I'm running ovs on Ubuntu 11.04 and noticed that it can process max. 200Mbps (NIC's are gigabit). It's used as an openflow switch with POX as controller and about 10 flows are installed. ovs is running with kernel module. The CPU is a quadcore Intel Xeon running at 2.2Ghz and one of the cores
