William Fisher pointed out that Ryu on Python 3 will raise exception when
failed negotiate the OpenFlow version. The following patches include the fix
for this issue.
Also, the following patches add a new option to close socket connecting to a
switch after sending a specified message.

method and this option enables to close the socket after sending the
given message. This patch is convenient to close the socket after
sending OFPT_ERROR message to the switch.

Hi Taha,
I couldn't investigate why, but on your attached log messages,
"EventSwitchLeave" are shown. Datapath might be disconnected for some reason,
then "EventLinkDelete" occurred.
Thanks,

Hi Ricardo,
I guess you caught a TCP SYN (or SYN+ACK or ACK) packet leading the BGP
handshake, so the received packet has no TCP payload.
I could get the BGP packets with the following modification of simple_switch_13.
diff --git a/ryu/app/simple_switch_13.py b/ryu/app/simple_switch_13.py
Hi Jade,
Just guessing, you enables IPv6 on your Mininet node? If so, IPv6 Neighbor
Discovery packets might be counted.
If you need to avoid these packets, please disable IPv6 settings on your
machine.
Thanks,
Iwase

Hi,
I'm using the newer version of OVS though, I guess OVS does not supports the
OpenFlow 1.5 structured FlowStats message.
the FlowStats message was restructured in the OpenFlow 1.5 according to
introduction of the FlowDesc message, but OVS does not implement the new
structure of the FlowStats
1.4 parsers for these messages.

Thank you for the response.

Hi Soliman,
The page you mentioned was written on OCTOBER 5, 2013 and the description might
be old (e.g., the default OpenFlow version on Mininet has been changed).
Please refer to the Ryu-Book for running "Switching Hub" application.
Hi Suresh and Thanks Yi!
FYI, Ryu provides "OpenFlow Switch Test Tool" for testing whether your switch
support the features of OpenFlow including the Meter.
This tool is one of the built-in application of Ryu and easy to start using.

Hmmm... I think it is depending on the switch implementation.
The OpenFlow Spec 1.3.5 says the recipient of OFPT_HELLO
Hi Reza,
How about getting the PortStats periodically?
This message contains "rx_dropped", "rx_errors" and so on.

Hi Tomas,
Because the contained "data" in the PACKET_IN message is an Ethernet frame
message, I guess it is difficult to implement such feature...
For example, you need to open another socket on tap interface for example, then
open "data" in PACKET_IN messages -> extract TCP payload -> forward
ny dpids as shown in
the attached image. Please let me know if I am following the correct steps.**
Thanks & Regards,

The following document is helpful for you?

Hi,
You are talking about "ryu.app.ofctl_rest", right?
http://ryu.readthedocs.io/en/latest/app/ofctl_rest.html
This application is an example application which provides the APIs related to
the OpenFlow protocol and none to other protocols.
If you mean the OVSDB protocol, I guess you need to use
