Hi all. I'm read some docs (mainly from openstack) that says how
create network isolation.
Does it possible to isolate one network from another by adding mpls
label (for example user id) and on recieve side accept packets only
with specific label?

Thanks I will give it a go. I was hoping to collect all traffic which has a
corresponding rule in the ofctl table but your comment on "not all packets
appearing in the datapath" has cast doubts over that.
CISCO Netflow samples the traffic, which is not good enough for me but I'll

Please don't drop the list.
Your flow_mod specifies an out_group other than OFPG_ANY with a command
other than OFPFC_DELETE or OFPFC_DELETE_STRICT. OVS responded with an
error.
However, I see that the OpenFlow spec says to just ignore out_group in
this case. I'll send out a patch in a minute.
Please don't drop the list.
I don't use POX, so you can list stuff that doesn't work with POX all
day and I won't be able to help. But if you provide a hex dump of the
OpenFlow message, then I can tell you what it's doing.

Hey All,
I am trying to add nw_proto with nicira extensions from pox.
I have been really struggling with this.
I want to add, nw_proto field on a table which is not the default one.
Eg: table_id=2 , dl_type =0x0800 , nw_proto=6
The only way is to go about nicira extensions since thats the only w
Hi All,
I have written a small pox as follows but in the OVS 2.0 it does not add the
nw_proto in the flow table.
The pox code is as follows:
# Turn on Nicira packet_ins
msg = nx.nx_packet_in_format()
event.connection.send(msg)
# Turn on ability to specify table in flow_mods

Have you considered using NetFlow?
There's no description of what goes into the kernel flow table because
that is an implementation detail subject to change. It's not an API of
any kind, certainly not a stable one.

I'm glad to hear that you worked around the problem.
By the way, I thought that you made a good point earlier that nothing
was logged when packet-ins were dropped, so I sent out a patch to fix
that. I credited and CCed you on it.

Thank you for response!
The problem was with MTU on Lo iface, after increasing it the TCP window
increased up to the limit specified by socket on controller's side and
packet drops stopped.

Hi,
In an OVS 2.0.0 setup, where the data path is loaded with artificially
generated traffic by the clients, we observe the effect of different
routing algorithms on packet latency. The problem is, despite there exists
manually introduced hotspots (that is, switches under excessive traffic
load) i
