We are using p4_16 and are interested in adding open flow support.

Hi, Antonin @antoninbas and other seniors :).

Thanks for your help. My process goes well. But I still have some problem about adding openflow controller to my mininet demo based on bmv2.

I refered the message on P4-dev:

• Error on building soft switch with openflow agent

• connect own target with openflow to ryu

• From bmv1 to bmv2?

I learned a lot from your words. Then I started my work.

First I overrided the method "start" of the "OpenFlowEnabledP4Switch" class in the topo.py. Sencond, I installed the repo p4ofagent and p4-build successfully, generated and compiled the PD library for my P4 program named 'sw' using p4-build:

./configure --with-bmv2 P4_NAME=switch_bmv2 P4_PATH=/home/wasdns/sw/p4src/switch_bmv2.p4

Then I write a main.c file. Based on my understanding about p4ofagent, I have to open p4ofagent process for each switch in my topo. I referenced the main.c here: main.c bmv2_init.c
, and my idea is, call the function p4_pd_switch_bmv2_assign_device in pd.h with right notification socket for each switch in my topo, like this:

p4_pd_switch_bmv2_assign_device(0, "ipc:///tmp/bmv2-0-notifications.ipc", 22222);
p4_pd_switch_bmv2_assign_device(1, "ipc:///tmp/bmv2-1-notifications.ipc", 22223);
···

Is it right?

By the way, could you give me some advice about my next step? I have a little confused with the Makefile writing because of lacking experience. I refered the Makefile of 'switch' repo. I'm not sure if I should link the libs(eg. simple_switch.lo) of bmv2/targets/simple_switch in Makefile.

Thank you very much!

Best regards,
Chen.

Hello,
When I follow the steps to make p4ofagent, it show me the following error:
src/state.h:26:23: fatal error: p4_sim/pd.h: No such file or directory
#include "p4_sim/pd.h"
Could anyone tell me where I can find the correct header files or how to generate them?
Thank you.

Hello,
I am trying to build the p4ofagent repository. Unfortunately, I run into build errors.

bmv2

./autogen
./configure --with-pdfixed
make
sudo make install

p4ofagent

./autogen.sh
./configure
make p4ofagent CPPFLAGS=-D_BMV2_

The p4ofagent make fails with the following message:

make -f indigo-lib.mk indigo-lib

I tried to build it using gcc 4, 5, 6, and 7, it fails at any version. Any idea what could cause this build failure?

Hi @antoninbas and other seniors

I get the following error when installing p4ofagent. I have installed bmv2 with pdfixed and p4c-bm.

Need some urgent help

hello guy,
It's exciting to find this p4ofagent repository while doing some SDN,P4 and openflow research. I'm pretty appretiate your works. When I try to learn/use p4ofagent, I found that the tutorials is quit rare and the recommend live demo is also deprecated( p4facotry). So It would be very nice if you guys could do some toturials about uage of p4ofagent.
Jhon
