Hi,
This problem seems to be caused by Python syntax.
You are running Ryu on Python 2, right? But your application seems to
include Python 3’s syntax.
I recommend you to re-install Ryu into your Python 3’s environment and try
again.
Regards,
Iwase

Hi,
I need to handle the RYU application exit signal (could be CTRL+C) /event
in the program?
I need to some clean up (on third party application such as DB, Zookeeper,
etc) when RYU crashes or RYU Closed(CTRL+C) purposefully.
Any suggestions?

Yes i have to do even the message because the switch in mininet emulated by OVS
had to send to the controller a message that says to it that there's too
traffic in it so the controller have to say to others ignore it..i don't know
if a similar message exist i mean it's implemented yet do you kno

Hi,
Mininet uses Open vSwitch(OVS) as the default software switch to emulate
the OpenFlow network.
So OVS (NOT Mininet) generates the messages to send the controller.
If your OVS already has the implementation for sending your own messages,
you need to implement parser class in Ryu.
If not yet, yo
Hi,
simple_switch or (simple_switch_13) does not depend on stplib.
https://github.com/osrg/ryu/blob/master/ryu/app/simple_switch_13.py
Please investigate why "your" simple_switch requires stplib, first.
simple_switch_stp or (simple_switch_stp_13 on Ryu-Book) depends on stplib,
do you mean this?

Hi,
To implement a custom OpenFlow message in Ryu,
please add the definitions for your own messages into
ryu.ofproto.ofproto_v1_*_parser.
If you need to receive and parse messages, parser() method is required
and if you need to send messages, _serialize_body() method is required.

I am new to RYU and deciding to use it as my controller, i am currently

Dear All:
I tried with the newest udp parser and "dhcpPacket =
pkt.get_protocol(dhcp.dhcp)" worked well.
Please find the attached pach and give comments.**

As you pointed out, this application parses all PACKET-IN to handle DHCP

Bit this is a "simple" dhcp server.

Hi Shuoling Deng:
It is necessary to parse every packet-in message if you want controller be
a simple dhcp server.
Hi alyosha:
That's strange, because udp parser will check if it's a dhcp packet and
parser it..
maybe it is a bug for parsing udp packet.

Hello
Maybe you can try
dhcp_packet = pkt.get_protocol(dhcp.dhcp)
if not dhcp_packet:
# not dhcp packet

Nice to e-meet you. My name is Okano Yuu.
I created a new ryu application, simple_dhcp_server for DHCPServer.
I tested this application with 2 VMs, and this application worked well.
VM1... DHCPClient
VM2... DHCPServer(Ryu & OpenVSwitch)
I set one flowentry on OpenVSwitch "ovs-ofctl add-flow br
this solve my problem, thanks for your help

You can use DPSet application as follows.

Hello,
I have written some very basic and simple OF 1.2 applications for Ryu which
I am running against LINC (www.flowforwarding.org). Once I run the
application (ex. add flow), I have to CNTRL+C to get out of the same -
which means I get out of controller connectivity to switch (not my desire).
