Thank you Ben,
I did try enqueue action of the OpenFlow and used the
ofp_queue_stats_request. I got this in the reply.
DEBUG:misc.of_tutorial:QueueStatsReceived from 00-00-00-00-00-01:
[{'tx_bytes': 42, 'queue_id': 0, 'tx_packets': 1, 'port_no': 1,
'tx_errors': 0}]
Now i am looking for some more

I do not think you read the answer. Please read it again. "But, if you
set up OpenFlow flows on your own, through a controller or using
ovs-ofc
ofp_stats_request will return stats of queues in the OVS database.

Hi Ben,
I want to get the "stats" of queues created in the OVS-database in the POX
controller.
Is it possible with the *ofp_stats_request* mentioned in the POX wiki? Or
do i need to use "tc" to add queues.

Geetha

I think the best option for me would be to do what I believe the reference
implementation and NEC's switch do: by default, when you set multiple
controllers, the switch connects to the first controller and uses the other
controllers in the list as backup controllers, trying them in round-robin o
Hi Aaron,
thanks for you quick response.
So the whole L2 separation of the tenants is done via flow
configuration. And the gre tunnel are merely there to connect the br-tun
on the compute nodes with the br-tun on the L2 Node?
Unfortunately I do not have a running Quantum installation, yet,
there

Hi List,
I hope this is ok to ask here. I looked through the Code of Quantum and
I don't understand how the gre tunneling is working.
I have two bridges br-int and br-tun, both are connected via a patch
port. But on the br-tun I do have several tunnel, for each tenant one?
How do I direct the traf
I don't know of any function by that name. I think you have a
vocabulary problem.
What do you want to do to the queues?

Sure Ben, but my question was how to access the queues of the OVS DB from
the POX controller. I happen to look at the OpenFlow switch spec and found
ofp_queue_get_config_request.
Even i am not sure if that function is relevant and i can use it.
Thanks,
Geetha

ofp_queue_get_config_request() appears to be part of NOX. The OVS
mailing lists are not a good place to ask questions about NOX.

Hello.
I read that GSO technology is used to reduce CPU overhead. So NIC recieves
big packet from CPU and splits them into small packets. Or, conversely, NIC
receives a set of small packets and then combines it into one large packet
to process on CPU.
But in queue_gso_packets function we receives

skb_push function extends the used data area of the buffer at the buffer
start.
It substracts skb->data by len - this is right, because we extends data
space at the start. But why this function adds skb->len by len, not
skb->data_len?
I think that total size of our buffer is the same - he

I have created some queues in mininet 2.0 using OVS-VSCTL and want to get
these statistics into my controller.
I am using POX.
