Hi haider,
Let me explain,
Does Ryu work with python 3.x or compatible with python 3.x?
Yes. It is.
Ryu is started 6-7 years back ,I guess that time python 3 is not matured.
2.7 was best fit.
When python 3 evolves, Ryu team made Ryu project compatible to work with
python 3 using adapter
Use ovs 2.9.x

Hi,
It's a strange question.
In ofctl rest application, packet-in/packet-in msg are not handled
1) . Is there any possibility by technically/logically pass the packetin

2) similaly packetout rest API can be added for sending packet out.

14.04 OVS version is 2.0.2, and the same code could not talk

In OVS 2.0.2 version, Is the port number different?

I referred earlier mailing list, and it was mentioned as,

But this gives only payload for TCP or UDP Protocols.

Hi Iwase,
When i configure route_reflector, RYU BGP Speaker couldnt establish the
comminication with traditional bird router.
My code snippet is as below,
# code snippet
self.bgp_speaker = BGPSpeaker(64511, router_id,
ssh_console=True,
Can we run multiple BGP Speakers in the RYU application?

And I am setting up two queues in Port 2. The queue number would be 3, 4.
So overall 5 queues.
I should use correct queue number (respect to port number), to apply Queue
OFPActionSetQueue(queue_id).
Is this correct?

I need to handle the RYU application exit signal (could be CTRL+C) /event

I need to some clean up (on third party application such as DB, Zookeeper,

Hi,
Just want to know more about, how the "packet in" messages are handled by
RYU controller.
I mean, code / file name. And some docs to understand that.
Thanks
Suresh

Hi,
I see couple of mail threads related to BGP stuff.I couldn't understand
the use case of the BGP with SDN. Can some one point that reference links
/ use case details for BGP in SDN Controllers.
Thanks

All,
I just released the SDN Beginners (with RYU exercises) course in udemy.
This course is primarily for beginners to learn RYU, and Mininet.
Course Link:

ackages/ryu/app/simple_switch_stp.py", line
85, in packet_in_handler
dst, src, _eth_type = struct.unpack_from('!6s6sH', buffer(msg.data), 0)
NameError: name 'buffer' is not defined
But in 2.7, it works perfectly.

Can we have multiple controllers in the Ryu application.

Each application consists of app.py, controller.py(REST handler) and
application files.
All the
