Geza,
Thanks for your insight.
- What is the packet size you see these bandwidth values?
A: I've tried various packet sizes with iperf, no significant differences.
- What endpoints do you use for traffic generation?
A: The bandwidth in question was measured from host to host, no VMs
involved.

Hello Justin,
I would like to find delay between two OVS switches that have been
connected. So, I need to have the timestamp of the packets that have been
entering the switch. I would like to store the timestamp of the packets in
a file by uniquely representing the packets. Could I do this by alte
I'd like to change the value of miss_send_len.
I use trema as Openflow v1.0 controller and trema ｉｓ not implemented SetConfig
messege.
So I can't send SetConfig messege from Openflow v1.0 controller.
Please tell me the other way.

Hello Justin,
I would like to uniquely identify a packet that is being going through the
switch and store it in a file with the timestamp when it reaches an OVS.
This is what I mentioned as capturing timestamps initially. Could I do this
by altering the code in datapath module?
Thank you,
Ajeeth
As I mentioned before, please don't drop the mailing list.
It's open source, so you're free to modify the datapath. Once again, I don't
know what you're storing or where you'd store it, but you can modify the code
on your system as much as you'd like. It's not clear whether the patches would
Please don't drop the list.
The dataplane is just forwarding packets through it, so I'm not sure what it
would store. For a particular datapath flow, we keep the last time that a
packet hit it, but that's about it. As I mentioned, if you want to send copies
of packets to a collector, you coul

OVS can't really influence whether a VM sends a reply.

More strangeness: when pinging from within VM behind port 13 I observe
even the reply coming back into VM yet ping reports no reply 100%
loss. This is with dl_dst:so:me:ma:cc flow. Why would that flow cause
that, how is that even possible if I'm seeing ICMP replies inside VM?
Again, all works fine
Hello All,
I am currently using OVS for Vxlan tunneling, and it works fine. I am
planning to try out OVS with DPDK to do the same Vxlan tunneling, and was
wondering if OVS supports such Vxlan tunneling with DPDK.
Thanks!

That's the requirement, that's why I started this topic. I've
demonstrated that port 13 works perfectly fine with no-flood as long
as the mac-table of openvswitch is populated with its MAC, I still
don't understand why we can't adding a static entry here, seems silly.
But I've pretty much accomplis

Yes of course I've opened up the switch again after flushing ;]
Basically I have:

Hi, all:
I have met a core dump issue when I ifconfig down vxlan-port durning
sending vxlan packets.
We know that when ifconfig down vxlan port, the udp socket will be
freed, but vxlan_xmit_one will still using the socket to do the send action,
and then a NULL is read.
Hello,
I don’t know where I can ask my question, so I did it here.
In our infrastructure we would like to build VXLAN tunnel between our
datacenters and we use Openvswitch for that. The main issue we are now facing
is the High Availability.
We’ve already try a solution with keepalived to do ac
