You mean;

right?
*Yes that's exactly what is happening.*
I will check the specification of Open V Switch
and I will let you know any thing.
Thanks

Hi Carlos,
You mean;

right?
If group and flow entries are installed as expected, it means this problem is
not on Ryu (Controller) side, but I guess it is on your switch spec. Please
confirm your
Hey Iwase,
Good news it's working although I couldn't really divide the flow.
Here's what happened.
The flow went to two ports of the switch but the flow is replicated on the
port 2 and 3.
in that case making the same bandwidth go on the port 2 and 3.
I used both *weight* variable as *0* an
Hi Carlos,

This rule does not follow "7.2.3.6 Flow Match Field Prerequisite" in the
OpenFlow Spec 1.3.5, I guess. See the OpenFlow Spec for more details.
Then, please confirm your flow entries are installed on your swi
Hey Iwase,
Right now my code looks like this OFPActionGroup is in Red

*queue_1 = _parser_.OFPActionSetQueue(0)*
*actions_1 = [queue_1, _parser_.OFPActionOutput(4)]*
*port_2 = 2*

*actions_2 = [
Hi Carlos,
H... have you installed any "flow" entry which contained OFPActionGroup?
Also, in your code, you uses "group_id = 50" in OFPGroupMod message. Is
OFPActionGroup using the same "group_id = 50"?
Thanks,
Iwase

Hi Iwase,
Sorry for the late answer
well... I checked the group stats as you said and it's not being looked up

Hi Carlos,
The group entries are looked up (or specified) by OFPActionGroup in flow
entries.
If looked up, ref_count, packet_count and byte_count should be incremented.

Hi Iwase,
The group entry is added...
but I don't understand how can be looked up.
I don't know how to do this
Is there any other thing that I am missing
thanks in advanced

"Does not work" means
- no group entry added
- group entry exists, but
Hey Iwase,
"*using the group table with openflow 1.3 with no sucess*" means that I am
using the group table as i said before and it is not working, means that I
am using the group specification and it doens't work.
and about your topology: It has only 2 switches or 4???
i don't know if my code
Hi Carlos,
For such purpose, OFPGT_SELECT is appropriate, I guess.
With the topology;

Hey Iwase,
Split means really divide the flow I dont know if would be like a load
balancing (I think it is)
For example the image below
But I dont know if this would be possible using the group table.

What does "split flows" exactly mean?

If you specify OFPGT_SELECT, switch will execute "one" bucket in the group and
not copied like the port mirroring. If you intend t
Hi there,
I know this topic was discussed before but I would like just a simple
explanation about it.
Because I am using the group table with openflow 1.3 with no sucess.
My purpose is to split one flow in two flows and forward on port 3 and 4
using the group table.
My code is as follows:
